Writing a science fair project report may seem like a challenging task, but it is not as difficult as it first appears. This is a format that you may use to write a science project report. If your project included animals, humans, hazardous materials, or regulated substances, you can attach an appendix that describes any special activities your project required. Also, some reports may benefit from additional sections, such as abstracts and bibliographies. You may find it helpful to fill out the science fair lab report template to prepare your report.

Important: Some science fairs have guidelines put forth by the science fair committee or an instructor. If your science fair has these guidelines, be sure to follow them.

Title: For a science fair, you probably want a catchy, clever title. Otherwise, try to make it an accurate description of the project. For example, I could entitle a project, "Determining Minimum NaCl Concentration That Can Be Tasted in Water." Avoid unnecessary words, while covering the essential purpose of the project. Whatever title you come up with, get it critiqued by friends, family, or teachers.
Introduction and Purpose: Sometimes this section is called "background." Whatever its name, this section introduces the topic of the project, notes any information already available, explains why you are interested in the project, and states the purpose of the project. If you are going to state references in your report, this is where most of the citations are likely to be, with the actual references listed at the end of the entire report in the form of a bibliography or reference section.
The Hypothesis or Question: Explicitly state your hypothesis or question.
Materials and Methods: List the materials you used in your project and describe the procedure that you used to perform the project. If you have a photo or diagram of your project, this is a good place to include it.
Data and Results: Data and results are not the same things. Some reports will require that they be in separate sections, so make sure you understand the difference between the concepts. Data refers to the actual numbers or other information you obtained in your project. Data can be presented in tables or charts, if appropriate. The results section is where the data is manipulated or the hypothesis is tested. Sometimes this analysis will yield tables, graphs, or charts, too. For example, a table listing the minimum concentration of salt that I can taste in water, with each line in the table being a separate test or trial, would be data. If I average the data or perform a statistical test of a null hypothesis , the information would be the results of the project.
Conclusion: The conclusion focuses on the hypothesis or question as it compares to the data and results. What was the answer to the question? Was the hypothesis supported (keep in mind a hypothesis cannot be proved, only disproved)? What did you find out from the experiment? Answer these questions first. Then, depending on your answers, you may wish to explain the ways in which the project might be improved or introduce new questions that have come up as a result of the project. This section is judged not only by what you were able to conclude but also by your recognition of areas where you could not draw valid conclusions based on your data.

Appearances Matter

Neatness counts, spelling counts, grammar counts. Take the time to make the report look nice. Pay attention to margins, avoid fonts that are difficult to read or are too small or too large, use clean paper, and make print the report cleanly on as good a printer or copier as you can.

Writing a Science Report

With science fair season coming up as well as many end of the year projects, students are often required to write a research paper or a report on their project. Use this guide to help you in the process from finding a topic to revising and editing your final paper.

Brainstorming Topics

Sometimes one of the largest barriers to writing a research paper is trying to figure out what to write about. Many times the topic is supplied by the teacher, or the curriculum tells what the student should research and write about. However, this is not always the case. Sometimes the student is given a very broad concept to write a research paper on, for example, water. Within the category of water, there are many topics and subtopics that would be appropriate. Topics about water can include anything from the three states of water, different water sources, minerals found in water, how water is used by living organisms, the water cycle, or how to find water in the desert. The point is that “water” is a very large topic and would be too broad to be adequately covered in a typical 3-5 page research paper.

When given a broad category to write about, it is important to narrow it down to a topic that is much more manageable. Sometimes research needs to be done in order to find the best topic to write about. (Look for searching tips in “Finding and Gathering Information.”) Listed below are some tips and guidelines for picking a suitable research topic:

Pick a topic within the category that you find interesting. It makes it that much easier to research and write about a topic if it interests you.
You may find while researching a topic that the details of the topic are very boring to you. If this is the case, and you have the option to do this, change your topic.
Pick a topic that you are already familiar with and research further into that area to build on your current knowledge.
When researching topics to do your paper on, look at how much information you are finding. If you are finding very little information on your topic or you are finding an overwhelming amount, you may need to rethink your topic.
If permissible, always leave yourself open to changing your topic. While researching for topics, you may come across one that you find really interesting and can use just as well as the previous topics you were searching for.
Most importantly, does your research topic fit the guidelines set forth by your teacher or curriculum?

Finding and Gathering Information

There are numerous resources out there to help you find information on the topic selected for your research paper. One of the first places to begin research is at your local library. Use the Dewey Decimal System or ask the librarian to help you find books related to your topic. There are also a variety of reference materials, such as encyclopedias, available at the library.

A relatively new reference resource has become available with the power of technology – the Internet. While the Internet allows the user to access a wealth of information that is often more up-to-date than printed materials such as books and encyclopedias, there are certainly drawbacks to using it. It can be hard to tell whether or not a site contains factual information or just someone’s opinion. A site can also be dangerous or inappropriate for students to use.

You may find that certain science concepts and science terminology are not easy to find in regular dictionaries and encyclopedias. A science dictionary or science encyclopedia can help you find more in-depth and relevant information for your science report. If your topic is very technical or specific, reference materials such as medical dictionaries and chemistry encyclopedias may also be good resources to use.

If you are writing a report for your science fair project, not only will you be finding information from published sources, you will also be generating your own data, results, and conclusions. Keep a journal that tracks and records your experiments and results. When writing your report, you can either write out your findings from your experiments or display them using graphs or charts .

*As you are gathering information, keep a working bibliography of where you found your sources. Look under “Citing Sources” for more information. This will save you a lot of time in the long run!

Organizing Information

Most people find it hard to just take all the information they have gathered from their research and write it out in paper form. It is hard to get a starting point and go from the beginning to the end. You probably have several ideas you know you want to put in your paper, but you may be having trouble deciding where these ideas should go. Organizing your information in a way where new thoughts can be added to a subtopic at any time is a great way to organize the information you have about your topic. Here are two of the more popular ways to organize information so it can be used in a research paper:

Graphic organizers such as a web or mind map . Mind maps are basically stating the main topic of your paper, then branching off into as many subtopics as possible about the main topic. Enchanted Learning has a list of several different types of mind maps as well as information on how to use them and what topics fit best for each type of mind map and graphic organizer.
Sub-Subtopic: Low temperatures and adequate amounts of snow are needed to form glaciers.
Sub-Subtopic: Glaciers move large amounts of earth and debris.
Sub-Subtopic: Two basic types of glaciers: valley and continental.
Subtopic: Icebergs – large masses of ice floating on liquid water

Different Formats For Your Paper

Depending on your topic and your writing preference, the layout of your paper can greatly enhance how well the information on your topic is displayed.

1. Process . This method is used to explain how something is done or how it works by listing the steps of the process. For most science fair projects and science experiments, this is the best format. Reports for science fairs need the entire project written out from start to finish. Your report should include a title page, statement of purpose, hypothesis, materials and procedures, results and conclusions, discussion, and credits and bibliography. If applicable, graphs, tables, or charts should be included with the results portion of your report.

2. Cause and effect . This is another common science experiment research paper format. The basic premise is that because event X happened, event Y happened.

3. Specific to general . This method works best when trying to draw conclusions about how little topics and details are connected to support one main topic or idea.

4. Climatic order . Similar to the “specific to general” category, here details are listed in order from least important to most important.

5. General to specific . Works in a similar fashion as the method for organizing your information. The main topic or subtopic is stated first, followed by supporting details that give more information about the topic.

6. Compare and contrast . This method works best when you wish to show the similarities and/or differences between two or more topics. A block pattern is used when you first write about one topic and all its details and then write about the second topic and all its details. An alternating pattern can be used to describe a detail about the first topic and then compare that to the related detail of the second topic. The block pattern and alternating pattern can also be combined to make a format that better fits your research paper.

Citing Sources

When writing a research paper, you must cite your sources! Otherwise you are plagiarizing (claiming someone else’s ideas as your own) which can cause severe penalties from failing your research paper assignment in primary and secondary grades to failing the entire course (most colleges and universities have this policy). To help you avoid plagiarism, follow these simple steps:

Find out what format for citing your paper your teacher or curriculum wishes you to use. One of the most widely used and widely accepted citation formats by scholars and schools is the Modern Language Association (MLA) format. We recommended that you do an Internet search for the most recent format of the citation style you will be using in your paper.
Keep a working bibliography when researching your topic. Have a document in your computer files or a page in your notebook where you write down every source that you found and may use in your paper. (You probably will not use every resource you find, but it is much easier to delete unused sources later rather than try to find them four weeks down the road.) To make this process even easier, write the source down in the citation format that will be used in your paper. No matter what citation format you use, you should always write down title, author, publisher, published date, page numbers used, and if applicable, the volume and issue number.
When collecting ideas and information from your sources, write the author’s last name at the end of the idea. When revising and formatting your paper, keep the author’s last name attached to the end of the idea, no matter where you move that idea. This way, you won’t have to go back and try to remember where the ideas in your paper came from.
There are two ways to use the information in your paper: paraphrasing and quotes. The majority of your paper will be paraphrasing the information you found. Paraphrasing is basically restating the idea being used in your own words. As a general rule of thumb, no more than two of the original words should be used in sequence when paraphrasing information, and similes should be used for as many of the words as possible in the original passage without changing the meaning of the main point. Sometimes, you may find something stated so well by the original author that it would be best to use the author’s original words in your paper. When using the author’s original words, use quotation marks only around the words being directly quoted and work the quote into the body of your paper so that it makes sense grammatically. Search the Internet for more rules on paraphrasing and quoting information.

Revising and Editing Your Paper

Revising your paper basically means you are fixing grammatical errors or changing the meaning of what you wrote. After you have written the rough draft of your paper, read through it again to make sure the ideas in your paper flow and are cohesive. You may need to add in information, delete extra information, use a thesaurus to find a better word to better express a concept, reword a sentence, or just make sure your ideas are stated in a logical and progressive order.

After revising your paper, go back and edit it, correcting the capitalization, punctuation, and spelling errors – the mechanics of writing. If you are not 100% positive a word is spelled correctly, look it up in a dictionary. Ask a parent or teacher for help on the proper usage of commas, hyphens, capitalization, and numbers. You may also be able to find the answers to these questions by doing an Internet search on writing mechanics or by checking you local library for a book on writing mechanics.

It is also always a good idea to have someone else read your paper. Because this person did not write the paper and is not familiar with the topic, he or she is more likely to catch mistakes or ideas that do not quite make sense. This person can also give you insights or suggestions on how to reword or format your paper to make it flow better or convey your ideas better.

How to Write a Convincing Science Fair Research Proposal

Do you have a plan for applying to college?

With our free chancing engine, admissions timeline, and personalized recommendations, our free guidance platform gives you a clear idea of what you need to be doing right now and in the future.

For students interested in the STEM fields, there are many extracurriculars to choose from. You might join the Math or Science Olympiad team, you could join the Computer Science Club, or you could even volunteer as a naturalist at a local conservation area.

If you are interested in scientific research, you might pursue the opportunity to secure a research assistant position or shadow various scientific researchers. But if you truly want to take the helm and guide your own research, your path may lead you to participating in the science fair.

The science fair is a traditional component of many high school science programs, with participation ranging widely from school to school and science fair to science fair. At some schools, the science fair might be a rite of passage expected of every student. At others, it attracts a handful of dedicated science die-hards.

Regardless, most science fairs feature presentations by students who have completed experiments, demonstrated scientific principles, or undertaken an engineering challenge. Participants are judged by a panel of experts who score each presentation according to a rubric. Traditionally, awards are presented for the top-scoring projects.

There are many science fairs beyond school-sponsored fairs, too. Regional, state, national, and even international fairs are open to students who qualify through their schools and work their way up through the science fair circuit. Others, like the Regeneron Science Talent Search, are open through an intensive application process.

If you are considering entering a project in the science fair, you will need to think carefully about your subject matter, your experimental design, and the relevance of your work before committing to a project. Many science fairs will even require that you complete a formal research proposal to demonstrate the level of thinking you’ve put into your experiment before beginning it.

In this post, we will outline the purpose of a research proposal for the science fair, the common elements of such a proposal, and how you can go about writing a comprehensive research proposal that is sure to impress.

What is the Purpose of a Research Proposal?

A research proposal has three primary purposes. The first purpose is to explain what you intend to do. This is essentially what you will do in your experiment or project, summarized into a basic overview.

The second function of a research proposal is to explain how you intend to accomplish this. You will give a brief summary of the methods and techniques that you intend to employ, and list the materials that you will need to do so.

The final point of a research proposal is to explain why this project should be done. Here, you will discuss the important or relevance of this study. Basically, in this portion of your proposal you’ll answer the question, “so what?”

Now that you know the aim of a research proposal, you can begin to prepare to write one. -->

Step-By-Step Guide to Creating a Research Proposal

1. narrow down the subject area..

Before you go into your project in any sort of depth, you’ll need a fairly good idea of what your project’s focus will be. In order to narrow this down, you should consider a few different angles.

First, ask yourself what you’re interested in. You will be more likely to feel engaged and passionate about a project that is genuinely interesting to you, so take some time to carefully consider the areas of science that you find the most fascinating. Even if they don’t seem particularly well-suited to a science fair project at first, you never know what you might be able to come up with through some collaboration with mentors or through some background research. Keep a running list of areas of science that sincerely fascinate you.

Next, consider any specialized labs or equipment to which you might have access. Does your best friend’s mother work in a lab with highly specialized tools? Does your school have a state-of-the-art wind tunnel or fully equipped greenhouse? These are all possible resources you can utilize if you want your project to truly stand out. Of course, it’s completely possible to choose a project that shines on its own without any specialized equipment, but if you’re looking for every boost you might get, having access to specialized technology can be a great advantage to make your project truly unique.

Finally, consider if you know a teacher or other professional who might be willing to mentor you. You can also seek out a mentor specifically if you can’t think of anyone obvious. Having a mentor in your field will provide you with invaluable insight into practice and past research in the field.

In the ideal world, you would find a project that maximizes all of your resources, including your interests, access to equipment, and an enthusiastic mentor. Don’t worry if you can’t secure all three, though. Plenty of science fair participants go on to do quite well relying on only their own dogged determination and commitment to their subject matter.

2 . Decide How Your Experiment Will Be Done

If you have a mentor, teacher, or adviser willing to consult with you, schedule a time to sit down with them and discuss what you’d like to do. If you can’t find someone more experienced than you, even discussing your ideas with a trusted classmate, parent, or older sibling is a good idea. Sometimes the outside perspective will help to fine-tune your design or identify areas for improvement.

You should also begin some research at this stage to learn how similar projects have been conducted in the past. Use the results and limitations from these experiments to help guide your own experimental design.

As you do so, keep in mind any limiting factors. Remember to consider what equipment you have at your disposal, the time commitment you’re able to make, and the materials that you’ll need to acquire.

In addition, be sure to check the rules of the specific science fairs you’ll be attending. Some have strict regulations designed to keep you safe, like limiting the ways in which potentially hazardous chemicals can be used. Other rules are designed to keep the environment safe, like placing restrictions on how you dispose of foreign substances or non-native species. There are also ethical rules that govern the use of human participants or vertebrate animals in your studies. Make sure to check which rules govern the fair in which you’re participating and how they might impact your ideas before you put any more thought into your project.

Discover your chances at hundreds of schools

Our free chancing engine takes into account your history, background, test scores, and extracurricular activities to show you your real chances of admission—and how to improve them.

3. Background Research

Your background research should be fairly comprehensive at this point and will be the single largest component of your research proposal. You should focus on your research on relevant past studies that inform your work either by identifying areas for future research or by identifying limiting factors in their own research. You should also research past experiments that support or attempt to disprove your working theory.

Finally, your research should clearly show why the project is relevant. What is important about it? What does it add to the field? Why should we care? Make sure that you can communicate the scientific value of the project you’re proposing.

4. Write Your Proposal

Once you’ve chosen a project, decided how you’ll undertake it, and done the relevant background research, you are finally able to begin drafting your research proposal. Check with your school or science fair to see if there is a specific format or form that you’re required to adhere to. If not, and you are producing a general research proposal, follow this format:

This should be a one-paragraph description of the project, your hypothesis, and the goals of your experiment. Here, you provide a brief overview of your project for anyone who is skimming your work.

Introduction/Literature Review:

This is the bulk of your proposal. In your literature review, you present what is currently known about your project’s focus and summarize relevant research that has been done in the field. You will discuss previous discoveries in your field, including how they were made and what they lend to your current work.

You will also show what is interesting and ground-breaking about your research idea. In this section you will need to summarize why your project is relevant, what makes it important, and how the field or current base of knowledge could change or be improved due to your project’s results.

As you write your literature review, you’ll need to be sure that you’re using high-quality, accurate sources. It’s best to rely on scholarly journal articles or reference books. Be wary of using the Internet, as many sources are unverified. If you are using online resources, be sure to verify their source. Published, peer-reviewed scholarly articles are best.

It’s also important to include proper citations for every source cited. You’ll need to list all your sources in the appropriate format in your bibliography along with citing them in the text of your proposal when you quote directly or reference specific data. If you aren’t sure how to cite properly, check out the Scientific Style and Format page.

Hypothesis:

This is the working theory that you are testing and what you expect the results will be, based off what you have learned through your background research.

Materials and Methods:

In this section you’ll provide a precise, in depth description of how you plan to test your hypothesis and what tools or materials you’ll need to do so. Summarize your experimental design, specifically referring to how you will control and replicate the experiment. Also list the equipment and materials that you will need for undertaking your experiment.

Conclusion:

Here, you will reiterate how your proposed research will advance knowledge in the scientific field and outline any potential longterm impact that your work could have on theory or practice within the field.

Bibliography:

List all sources used in appropriate format. Refer to the Scientific Style and Format page if you aren’t sure how to do so.

What Happens After I Submit a Research Proposal?

After you submit the research proposal, it will be reviewed by your teacher or a science fair administrator or adviser. It will be approved, rejected, or returned for revisions based on its feasibility, value to the scientific field, and adherence to the science fair rules and regulations.

While larger, more selective science fairs will have to select only a limited number of candidates based on the merits of their research proposals, it is fairly uncommon for a science fair research proposal to get completely denied at the school level. Usually, in these cases, your proposal will be returned to you with requests for edits or further clarification. You have most likely consulted with your teacher or adviser throughout the process of developing your proposal, so nothing should come as a complete surprise when you receive feedback.

If your proposal is rejected and you don’t receive constructive feedback, don’t be shy about respectfully requesting some feedback to help you shape a better, more effective proposal in the future.

If your proposal is returned for revisions, you should feel encouraged. While you still have some work to do, this is generally a sign that with a few tweaks, your proposal will be accepted. Meet with a teacher, mentor, or adviser to review the revisions requested and address each thoroughly before returning the proposal for another round of review.

If your proposal is accepted, congratulations! It’s time to get to work. While your proposal itself was probably a time-consuming endeavor, your research will ultimately be easier for having taken the time and care to craft a precise proposal. Your research will be more focused and likely a smoother process due to all your careful planning, and you will be able to use large chunks of your written work in your final scientific report.

Don’t be intimidated if you’re getting ready to write a science fair research proposal. It can be a long process to fine-tune your project and focus your proposed research, but the work that you put in now ultimately makes your job easier in the long run.

What Is a Science Essay?

A science essay is an academic paper focusing on a scientific topic from physics, chemistry, biology, or any other scientific field.

Science essays are mostly expository. That is, they require you to explain your chosen topic in detail. However, they can also be descriptive and exploratory.

A descriptive science essay aims to describe a certain scientific phenomenon according to established knowledge.

On the other hand, the exploratory science essay requires you to go beyond the current theories and explore new interpretations.

So before you set out to write your essay, always check out the instructions given by your instructor. Whether a science essay is expository or exploratory must be clear from the start. Or, if you face any difficulty, you can take help from a science essay writer as well.

Moreover, check out this video to understand scientific writing in detail.

Now that you know what it is, let's look at the steps you need to take to write a science essay.

Paper Due? Why Suffer? That's our Job!

How To Write a Science Essay?

Writing a science essay is not as complex as it may seem. All you need to do is follow the right steps to create an impressive piece of work that meets the assigned criteria.

Here's what you need to do:

Choose Your Topic

A good topic forms the foundation for an engaging and well-written essay. Therefore, you should ensure that you pick something interesting or relevant to your field of study.

To choose a good topic, you can brainstorm ideas relating to the subject matter. You may also find inspiration from other science essays or articles about the same topic.

Conduct Research

Once you have chosen your topic, start researching it thoroughly to develop a strong argument or discussion in your essay.

Make sure you use reliable sources and cite them properly . You should also make notes while conducting your research so that you can reference them easily when writing the essay. Or, you can get expert assistance from an essay writing service to manage your citations.

Create an Outline

A good essay outline helps to organize the ideas in your paper. It serves as a guide throughout the writing process and ensures you don’t miss out on important points.

An outline makes it easier to write a well-structured paper that flows logically. It should be detailed enough to guide you through the entire writing process.

However, your outline should be flexible, and it's sometimes better to change it along the way to improve your structure.

Start Writing

Once you have a good outline, start writing the essay by following your plan.

The first step in writing any essay is to draft it. This means putting your thoughts down on paper in a rough form without worrying about grammar or spelling mistakes.

So begin your essay by introducing the topic, then carefully explain it using evidence and examples to support your argument.

Don't worry if your first draft isn't perfect - it's just the starting point!

Proofread & Edit

After finishing your first draft, take time to proofread and edit it for grammar and spelling mistakes.

Proofreading is the process of checking for grammatical mistakes. It should be done after you have finished writing your essay.

Editing, on the other hand, involves reviewing the structure and organization of your essay and its content. It should be done before you submit your final work.

Both proofreading and editing are essential for producing a high-quality essay. Make sure to give yourself enough time to do them properly!

After revising the essay, you should format it according to the guidelines given by your instructor. This could involve using a specific font size, page margins, or citation style.

Most science essays are written in Times New Roman font with 12-point size and double spacing. The margins should be 1 inch on all sides, and the text should be justified.

In addition, you must cite your sources properly using a recognized citation style such as APA , Chicago , or Harvard . Make sure to follow the guidelines closely so that your essay looks professional.

Following these steps will help you create an informative and well-structured science essay that meets the given criteria.

How to Structure a Science Essay?

A basic science essay structure includes an introduction, body, and conclusion.

Let's look at each of these briefly.

Introduction

Your essay introduction should introduce your topic and provide a brief overview of what you will discuss in the essay. It should also state your thesis or main argument.

For instance, a thesis statement for a science essay could be,

"The human body is capable of incredible feats, as evidenced by the many athletes who have competed in the Olympic games."

The body of your essay will contain the bulk of your argument or discussion. It should be divided into paragraphs, each discussing a different point.

For instance, imagine you were writing about sports and the human body.

Your first paragraph can discuss the physical capabilities of the human body.

The second paragraph may be about the physical benefits of competing in sports.

Similarly, in the third paragraph, you can present one or two case studies of specific athletes to support your point.

Once you have explained all your points in the body, it’s time to conclude the essay.

This article presents a detailed guide for high school through graduate level instructors that leads students to write effective and well-organized scientific papers. Interesting research emerges from the ability to ask questions, define problems, design experiments, analyze and interpret data, and make critical connections. This process is incomplete, unless new results are communicated to others because science fundamentally requires peer review and criticism to validate or discard proposed new knowledge. Thus, a concise and clearly written research paper is a critical step in the scientific process and is important for young researchers as they are mastering how to express scientific concepts and understanding. Moreover, learning to write a research paper provides a tool to improve science literacy as indicated in the National Research Council's National Science Education Standards (1996), and A Framework for K–12 Science Education (2011), the underlying foundation for the Next Generation Science Standards currently being developed. Background information explains the importance of peer review and communicating results, along with details of each critical component, the Abstract, Introduction, Methods, Results , and Discussion . Specific steps essential to helping students write clear and coherent research papers that follow a logical format, use effective communication, and develop scientific inquiry are described.

Introduction

A key part of the scientific process is communication of original results to others so that one's discoveries are passed along to the scientific community and the public for awareness and scrutiny. 1 – 3 Communication to other scientists ensures that new findings become part of a growing body of publicly available knowledge that informs how we understand the world around us. 2 It is also what fuels further research as other scientists incorporate novel findings into their thinking and experiments.

Depending upon the researcher's position, intent, and needs, communication can take different forms. The gold standard is writing scientific papers that describe original research in such a way that other scientists will be able to repeat it or to use it as a basis for their studies. 1 For some, it is expected that such articles will be published in scientific journals after they have been peer reviewed and accepted for publication. Scientists must submit their articles for examination by other scientists familiar with the area of research, who decide whether the work was conducted properly and whether the results add to the knowledge base and are conveyed well enough to merit publication. 2 If a manuscript passes the scrutiny of peer-review, it has the potential to be published. 1 For others, such as for high school or undergraduate students, publishing a research paper may not be the ultimate goal. However, regardless of whether an article is to be submitted for publication, peer review is an important step in this process. For student researchers, writing a well-organized research paper is a key step in learning how to express understanding, make critical connections, summarize data, and effectively communicate results, which are important goals for improving science literacy of the National Research Council's National Science Education Standards, 4 and A Framework for K–12 Science Education, 5 and the Next Generation Science Standards 6 currently being developed and described in The NSTA Reader's Guide to A Framework for K–12 Science Education. 7 Table 1 depicts the key skills students should develop as part of the Science as Inquiry Content Standard. Table 2 illustrates the central goals of A Framework for K–12 Science Education Scientific and Engineering Practices Dimension.

Scientific papers based on experimentation typically include five predominant sections: Abstract, Introduction, Methods, Results, and Discussion . This structure is a widely accepted approach to writing a research paper, and has specific sections that parallel the scientific method. Following this structure allows the scientist to tell a clear, coherent story in a logical format, essential to effective communication. 1 , 2 In addition, using a standardized format allows the reader to find specific information quickly and easily. While readers may not have time to read the entire research paper, the predictable format allows them to focus on specific sections such as the Abstract , Introduction , and Discussion sections. Therefore, it is critical that information be placed in the appropriate and logical section of the report. 3

Guidelines for Writing a Primary Research Article

The Title sends an important message to the reader about the purpose of the paper. For example, Ethanol Effects on the Developing Zebrafish: Neurobehavior and Skeletal Morphogenesis 8 tells the reader key information about the content of the research paper. Also, an appropriate and descriptive title captures the attention of the reader. When composing the Title , students should include either the aim or conclusion of the research, the subject, and possibly the independent or dependent variables. Often, the title is created after the body of the article has been written, so that it accurately reflects the purpose and content of the article. 1 , 3

The Abstract provides a short, concise summary of the research described in the body of the article and should be able to stand alone. It provides readers with a quick overview that helps them decide whether the article may be interesting to read. Included in the Abstract are the purpose or primary objectives of the experiment and why they are important, a brief description of the methods and approach used, key findings and the significance of the results, and how this work is different from the work of others. It is important to note that the Abstract briefly explains the implications of the findings, but does not evaluate the conclusions. 1 , 3 Just as with the Title , this section needs to be written carefully and succinctly. Often this section is written last to ensure it accurately reflects the content of the paper. Generally, the optimal length of the Abstract is one paragraph between 200 and 300 words, and does not contain references or abbreviations.

All new research can be categorized by field (e.g., biology, chemistry, physics, geology) and by area within the field (e.g., biology: evolution, ecology, cell biology, anatomy, environmental health). Many areas already contain a large volume of published research. The role of the Introduction is to place the new research within the context of previous studies in the particular field and area, thereby introducing the audience to the research and motivating the audience to continue reading. 1

Usually, the writer begins by describing what is known in the area that directly relates to the subject of the article's research. Clearly, this must be done judiciously; usually there is not room to describe every bit of information that is known. Each statement needs one or more references from the scientific literature that supports its validity. Students must be reminded to cite all references to eliminate the risk of plagiarism. 2 Out of this context, the author then explains what is not known and, therefore, what the article's research seeks to find out. In doing so, the scientist provides the rationale for the research and further develops why this research is important. The final statement in the Introduction should be a clearly worded hypothesis or thesis statement, as well as a brief summary of the findings as they relate to the stated hypothesis. Keep in mind that the details of the experimental findings are presented in the Results section and are aimed at filling the void in our knowledge base that has been pointed out in the Introduction .

Materials and Methods

Research utilizes various accepted methods to obtain the results that are to be shared with others in the scientific community. The quality of the results, therefore, depends completely upon the quality of the methods that are employed and the care with which they are applied. The reader will refer to the Methods section: (a) to become confident that the experiments have been properly done, (b) as the guide for repeating the experiments, and (c) to learn how to do new methods.

It is particularly important to keep in mind item (b). Since science deals with the objective properties of the physical and biological world, it is a basic axiom that these properties are independent of the scientist who reported them. Everyone should be able to measure or observe the same properties within error, if they do the same experiment using the same materials and procedures. In science, one does the same experiment by exactly repeating the experiment that has been described in the Methods section. Therefore, someone can only repeat an experiment accurately if all the relevant details of the experimental methods are clearly described. 1 , 3

The following information is important to include under illustrative headings, and is generally presented in narrative form. A detailed list of all the materials used in the experiments and, if important, their source should be described. These include biological agents (e.g., zebrafish, brine shrimp), chemicals and their concentrations (e.g., 0.20 mg/mL nicotine), and physical equipment (e.g., four 10-gallon aquariums, one light timer, one 10-well falcon dish). The reader needs to know as much as necessary about each of the materials; however, it is important not to include extraneous information. For example, consider an experiment involving zebrafish. The type and characteristics of the zebrafish used must be clearly described so another scientist could accurately replicate the experiment, such as 4–6-month-old male and female zebrafish, the type of zebrafish used (e.g., Golden), and where they were obtained (e.g., the NIEHS Children's Environmental Health Sciences Core Center in the WATER Institute of the University of Wisconsin—Milwaukee). In addition to describing the physical set-up of the experiment, it may be helpful to include photographs or diagrams in the report to further illustrate the experimental design.

A thorough description of each procedure done in the reported experiment, and justification as to why a particular method was chosen to most effectively answer the research question should also be included. For example, if the scientist was using zebrafish to study developmental effects of nicotine, the reader needs to know details about how and when the zebrafish were exposed to the nicotine (e.g., maternal exposure, embryo injection of nicotine, exposure of developing embryo to nicotine in the water for a particular length of time during development), duration of the exposure (e.g., a certain concentration for 10 minutes at the two-cell stage, then the embryos were washed), how many were exposed, and why that method was chosen. The reader would also need to know the concentrations to which the zebrafish were exposed, how the scientist observed the effects of the chemical exposure (e.g., microscopic changes in structure, changes in swimming behavior), relevant safety and toxicity concerns, how outcomes were measured, and how the scientist determined whether the data/results were significantly different in experimental and unexposed control animals (statistical methods).

Students must take great care and effort to write a good Methods section because it is an essential component of the effective communication of scientific findings.

The Results section describes in detail the actual experiments that were undertaken in a clear and well-organized narrative. The information found in the Methods section serves as background for understanding these descriptions and does not need to be repeated. For each different experiment, the author may wish to provide a subtitle and, in addition, one or more introductory sentences that explains the reason for doing the experiment. In a sense, this information is an extension of the Introduction in that it makes the argument to the reader why it is important to do the experiment. The Introduction is more general; this text is more specific.

Once the reader understands the focus of the experiment, the writer should restate the hypothesis to be tested or the information sought in the experiment. For example, “Atrazine is routinely used as a crop pesticide. It is important to understand whether it affects organisms that are normally found in soil. We decided to use worms as a test organism because they are important members of the soil community. Because atrazine damages nerve cells, we hypothesized that exposure to atrazine will inhibit the ability of worms to do locomotor activities. In the first experiment, we tested the effect of the chemical on burrowing action.”

Then, the experiments to be done are described and the results entered. In reporting on experimental design, it is important to identify the dependent and independent variables clearly, as well as the controls. The results must be shown in a way that can be reproduced by the reader, but do not include more details than needed for an effective analysis. Generally, meaningful and significant data are gathered together into tables and figures that summarize relevant information, and appropriate statistical analyses are completed based on the data gathered. Besides presenting each of these data sources, the author also provides a written narrative of the contents of the figures and tables, as well as an analysis of the statistical significance. In the narrative, the writer also connects the results to the aims of the experiment as described above. Did the results support the initial hypothesis? Do they provide the information that was sought? Were there problems in the experiment that compromised the results? Be careful not to include an interpretation of the results; that is reserved for the Discussion section.

The writer then moves on to the next experiment. Again, the first paragraph is developed as above, except this experiment is seen in the context of the first experiment. In other words, a story is being developed. So, one commonly refers to the results of the first experiment as part of the basis for undertaking the second experiment. “In the first experiment we observed that atrazine altered burrowing activity. In order to understand how that might occur, we decided to study its impact on the basic biology of locomotion. Our hypothesis was that atrazine affected neuromuscular junctions. So, we did the following experiment..”

The Results section includes a focused critical analysis of each experiment undertaken. A hallmark of the scientist is a deep skepticism about results and conclusions. “Convince me! And then convince me again with even better experiments.” That is the constant challenge. Without this basic attitude of doubt and willingness to criticize one's own work, scientists do not get to the level of concern about experimental methods and results that is needed to ensure that the best experiments are being done and the most reproducible results are being acquired. Thus, it is important for students to state any limitations or weaknesses in their research approach and explain assumptions made upfront in this section so the validity of the research can be assessed.

The Discussion section is the where the author takes an overall view of the work presented in the article. First, the main results from the various experiments are gathered in one place to highlight the significant results so the reader can see how they fit together and successfully test the original hypotheses of the experiment. Logical connections and trends in the data are presented, as are discussions of error and other possible explanations for the findings, including an analysis of whether the experimental design was adequate. Remember, results should not be restated in the Discussion section, except insofar as it is absolutely necessary to make a point.

Second, the task is to help the reader link the present work with the larger body of knowledge that was portrayed in the Introduction . How do the results advance the field, and what are the implications? What does the research results mean? What is the relevance? 1 , 3

Lastly, the author may suggest further work that needs to be done based on the new knowledge gained from the research.

Supporting Documentation and Writing Skills

Tables and figures are included to support the content of the research paper. These provide the reader with a graphic display of information presented. Tables and figures must have illustrative and descriptive titles, legends, interval markers, and axis labels, as appropriate; should be numbered in the order that they appear in the report; and include explanations of any unusual abbreviations.

The final section of the scientific article is the Reference section. When citing sources, it is important to follow an accepted standardized format, such as CSE (Council of Science Editors), APA (American Psychological Association), MLA (Modern Language Association), or CMS (Chicago Manual of Style). References should be listed in alphabetical order and original authors cited. All sources cited in the text must be included in the Reference section. 1

When writing a scientific paper, the importance of writing concisely and accurately to clearly communicate the message should be emphasized to students. 1 – 3 Students should avoid slang and repetition, as well as abbreviations that may not be well known. 1 If an abbreviation must be used, identify the word with the abbreviation in parentheses the first time the term is used. Using appropriate and correct grammar and spelling throughout are essential elements of a well-written report. 1 , 3 Finally, when the article has been organized and formatted properly, students are encouraged to peer review to obtain constructive criticism and then to revise the manuscript appropriately. Good scientific writing, like any kind of writing, is a process that requires careful editing and revision. 1

A key dimension of NRC's A Framework for K–12 Science Education , Scientific and Engineering Practices, and the developing Next Generation Science Standards emphasizes the importance of students being able to ask questions, define problems, design experiments, analyze and interpret data, draw conclusions, and communicate results. 5 , 6 In the Science Education Partnership Award (SEPA) program at the University of Wisconsin—Milwaukee, we found the guidelines presented in this article useful for high school science students because this group of students (and probably most undergraduates) often lack in understanding of, and skills to develop and write, the various components of an effective scientific paper. Students routinely need to focus more on the data collected and analyze what the results indicated in relation to the research question/hypothesis, as well as develop a detailed discussion of what they learned. Consequently, teaching students how to effectively organize and write a research report is a critical component when engaging students in scientific inquiry.

Writing an Introduction for a Scientific Paper

Dr. michelle harris, dr. janet batzli, biocore.

This section provides guidelines on how to construct a solid introduction to a scientific paper including background information, study question , biological rationale, hypothesis , and general approach . If the Introduction is done well, there should be no question in the reader’s mind why and on what basis you have posed a specific hypothesis.

Broad Question : based on an initial observation (e.g., “I see a lot of guppies close to the shore. Do guppies like living in shallow water?”). This observation of the natural world may inspire you to investigate background literature or your observation could be based on previous research by others or your own pilot study. Broad questions are not always included in your written text, but are essential for establishing the direction of your research.

Background Information : key issues, concepts, terminology, and definitions needed to understand the biological rationale for the experiment. It often includes a summary of findings from previous, relevant studies. Remember to cite references, be concise, and only include relevant information given your audience and your experimental design. Concisely summarized background information leads to the identification of specific scientific knowledge gaps that still exist. (e.g., “No studies to date have examined whether guppies do indeed spend more time in shallow water.”)

Testable Question : these questions are much more focused than the initial broad question, are specific to the knowledge gap identified, and can be addressed with data. (e.g., “Do guppies spend different amounts of time in water <1 meter deep as compared to their time in water that is >1 meter deep?”)

Biological Rationale : describes the purpose of your experiment distilling what is known and what is not known that defines the knowledge gap that you are addressing. The “BR” provides the logic for your hypothesis and experimental approach, describing the biological mechanism and assumptions that explain why your hypothesis should be true.

The biological rationale is based on your interpretation of the scientific literature, your personal observations, and the underlying assumptions you are making about how you think the system works. If you have written your biological rationale, your reader should see your hypothesis in your introduction section and say to themselves, “Of course, this hypothesis seems very logical based on the rationale presented.”

A thorough rationale defines your assumptions about the system that have not been revealed in scientific literature or from previous systematic observation. These assumptions drive the direction of your specific hypothesis or general predictions.
Defining the rationale is probably the most critical task for a writer, as it tells your reader why your research is biologically meaningful. It may help to think about the rationale as an answer to the questions— how is this investigation related to what we know, what assumptions am I making about what we don’t yet know, AND how will this experiment add to our knowledge? *There may or may not be broader implications for your study; be careful not to overstate these (see note on social justifications below).
Expect to spend time and mental effort on this. You may have to do considerable digging into the scientific literature to define how your experiment fits into what is already known and why it is relevant to pursue.
Be open to the possibility that as you work with and think about your data, you may develop a deeper, more accurate understanding of the experimental system. You may find the original rationale needs to be revised to reflect your new, more sophisticated understanding.
As you progress through Biocore and upper level biology courses, your rationale should become more focused and matched with the level of study e ., cellular, biochemical, or physiological mechanisms that underlie the rationale. Achieving this type of understanding takes effort, but it will lead to better communication of your science.

***Special note on avoiding social justifications: You should not overemphasize the relevance of your experiment and the possible connections to large-scale processes. Be realistic and logical —do not overgeneralize or state grand implications that are not sensible given the structure of your experimental system. Not all science is easily applied to improving the human condition. Performing an investigation just for the sake of adding to our scientific knowledge (“pure or basic science”) is just as important as applied science. In fact, basic science often provides the foundation for applied studies.

Hypothesis / Predictions : specific prediction(s) that you will test during your experiment. For manipulative experiments, the hypothesis should include the independent variable (what you manipulate), the dependent variable(s) (what you measure), the organism or system , the direction of your results, and comparison to be made.

If you are doing a systematic observation , your hypothesis presents a variable or set of variables that you predict are important for helping you characterize the system as a whole, or predict differences between components/areas of the system that help you explain how the system functions or changes over time.

Experimental Approach : Briefly gives the reader a general sense of the experiment, the type of data it will yield, and the kind of conclusions you expect to obtain from the data. Do not confuse the experimental approach with the experimental protocol . The experimental protocol consists of the detailed step-by-step procedures and techniques used during the experiment that are to be reported in the Methods and Materials section.

Some Final Tips on Writing an Introduction

As you progress through the Biocore sequence, for instance, from organismal level of Biocore 301/302 to the cellular level in Biocore 303/304, we expect the contents of your “Introduction” paragraphs to reflect the level of your coursework and previous writing experience. For example, in Biocore 304 (Cell Biology Lab) biological rationale should draw upon assumptions we are making about cellular and biochemical processes.
Be Concise yet Specific: Remember to be concise and only include relevant information given your audience and your experimental design. As you write, keep asking, “Is this necessary information or is this irrelevant detail?” For example, if you are writing a paper claiming that a certain compound is a competitive inhibitor to the enzyme alkaline phosphatase and acts by binding to the active site, you need to explain (briefly) Michaelis-Menton kinetics and the meaning and significance of Km and Vmax. This explanation is not necessary if you are reporting the dependence of enzyme activity on pH because you do not need to measure Km and Vmax to get an estimate of enzyme activity.
Another example: if you are writing a paper reporting an increase in Daphnia magna heart rate upon exposure to caffeine you need not describe the reproductive cycle of magna unless it is germane to your results and discussion. Be specific and concrete, especially when making introductory or summary statements.

Where Do You Discuss Pilot Studies? Many times it is important to do pilot studies to help you get familiar with your experimental system or to improve your experimental design. If your pilot study influences your biological rationale or hypothesis, you need to describe it in your Introduction. If your pilot study simply informs the logistics or techniques, but does not influence your rationale, then the description of your pilot study belongs in the Materials and Methods section.

How will introductions be evaluated? The following is part of the rubric we will be using to evaluate your papers.

What is a scientific report?

A scientific report documents all aspects of an experimental investigation. This includes:

The aim of the experiment
The hypothesis
An introduction to the relevant background theory
The methods used
The results
A discussion of the results
The conclusion

Scientific reports allow their readers to understand the experiment without doing it themselves. In addition, scientific reports give others the opportunity to check the methodology of the experiment to ensure the validity of the results.

A scientific report is written in several stages. We write the introduction, aim, and hypothesis before performing the experiment, record the results during the experiment, and complete the discussion and conclusions after the experiment.

But, before we delve deeper into how to write a scientific report, we need to have a science experiment to write about! Read our 7 Simple Experiments You Can Do At Home article and see which one you want to do.

General rules about writing scientific reports

Learning how to write a scientific report is different from writing English essays or speeches!

You have to use:

Passive voice (which you should avoid when writing for other subjects like English!)
Past-tense language
Headings and subheadings
A pencil to draw scientific diagrams and graphs
Simple and clear lines for scientific diagrams
Tables and graphs where necessary

Structure of scientific reports:

Now that you know the general rules on how to write scientific reports, let’s look at the conventions for their structure!

The title should simply introduce what your experiment is about.

The Role of Light in Photosynthesis

2. Introduction/Background information

Write a paragraph that gives your readers background information to understand your experiment.

This includes explaining scientific theories, processes and other related knowledge.

Photosynthesis is a vital process for life. It occurs when plants intake carbon dioxide, water, and light, and results in the production of glucose and water. The light required for photosynthesis is absorbed by chlorophyll, the green pigment of plants, which is contained in the chloroplasts.

The glucose produced through photosynthesis is stored as starch, which is used as an energy source for the plant and its consumers.

The presence of starch in the leaves of a plant indicates that photosynthesis has occurred.

blog-how-to-write-a-scientific-report-photosynthesis

The aim identifies what is going to be tested in the experiment. This should be short, concise and clear.

The aim of the experiment is to test whether light is required for photosynthesis to occur.

4. Hypothesis

The hypothesis is a prediction of the outcome of the experiment. You have to use background information to make an educated prediction.

It is predicted that photosynthesis will occur only in leaves that are exposed to light and not in leaves that are not exposed to light. This will be indicated by the presence or absence of starch in the leaves.

5. Risk assessment

Identify the hazards associated with the experiment and provide a method to prevent or minimise the risks. A hazard is something that can cause harm, and the risk is the likelihood that harm will occur from the hazard.

A table is an excellent way to present your risk assessment.

Remember, you have to specify the type of harm that can occur because of the hazard. It is not enough to simply identify the hazard.

Do not write: “Scissors are sharp”
Instead, you have to write: “Scissors are sharp and can cause injury”

blog-how-to-write-a-scientific-report-photosynthesis-risk

The method has 3 parts:

A list of every material used
Steps of what you did in the experiment
A scientific diagram of the experimental apparatus

Let’s break down what you need to do for each section.

6a. Materials

This must list every piece of equipment and material you used in the experiment.

Remember, you need to also specify the amount of each material you used.

1 geranium plant
Aluminium foil
2 test tubes
1 test tube rack
1 pair of scissors
1 250 mL beaker
1 pair of forceps
1 10 mL measuring cylinder
Iodine solution (5 mL)
Methylated spirit (50ml)
Boiling water
2 Petri dishes

blog-how-to-write-a-scientific-report-photosynthesis-material

The rule of thumb is that you should write the method in a clear way so that readers are able to repeat the experiment and get similar results.

Using a numbered list for the steps of your experimental procedure is much clearer than writing a whole paragraph of text. The steps should:

Be written in a sequential order, based on when they were performed.
Specify any equipment that was used.
Specify the quantity of any materials that were used.

You also need to use past tense and passive voice when you are writing your method. Scientific reports are supposed to show the readers what you did in the experiment, not what you will do.

Aluminium foil was used to fully cover a leaf of the geranium plant. The plant was left in the sun for three days.
On the third day, the covered leaf and 1 non-covered leaf were collected from the plant. The foil was removed from the covered leaf, and a 1 cm square was cut from each leaf using a pair of scissors.
150 mL of water was boiled in a kettle and poured into a 250 mL beaker.
Using forceps, the 1 cm square of covered leaf was placed into the beaker of boiling water for 2 minutes. It was then placed in a test tube labelled “dark”.
The water in the beaker was discarded and replaced with 150 mL of freshly boiled water.
Using forceps, the 1 cm square non-covered leaf was placed into the beaker of boiling water for 2 minutes. It was then placed in a test tube labelled “light”
5 mL of methylated spirit was measured with a measuring cylinder and poured into each test tube so that the leaves were fully covered.
The water in the beaker was replaced with 150 mL of freshly boiled water and both the “light” and “dark” test tubes were immersed in the beaker of boiling water for 5 minutes.
The leaves were collected from each test tube with forceps, rinsed under cold running water, and placed onto separate labelled Petri dishes.
3 drops of iodine solution were added to each leaf.
Both Petri dishes were placed side by side and observations were recorded.
The experiment was repeated 5 times, and results were compared between different groups.

6c. Diagram

After you finish your steps, it is time to draw your scientific diagrams! Here are some rules for drawing scientific diagrams:

Always use a pencil to draw your scientific diagrams.
Use simple, sharp, 2D lines and shapes to draw your diagram. Don’t draw 3D shapes or use shading.
Label everything in your diagram.
Use thin, straight lines to label your diagram. Do not use arrows.
Ensure that the label lines touch the outline of the equipment you are labelling and not cross over it or stop short of it
The label lines should never cross over each other.
Use a ruler for any straight lines in your diagram.
Draw a sufficiently large diagram so all components can be seen clearly.

blog-how-to-write-a-scientific-report-scientific-diagram-photosynthesis

This is where you document the results of your experiment. The data that you record for your experiment will generally be qualitative and/or quantitative.

Qualitative data is data that relates to qualities and is based on observations (qualitative – quality). This type of data is descriptive and is recorded in words. For example, the colour changed from green to orange, or the liquid became hot.

Quantitative data refers to numerical data (quantitative – quantity). This type of data is recorded using numbers and is either measured or counted. For example, the plant grew 5.2 cm, or there were 5 frogs.

You also need to record your results in an appropriate way. Most of the time, a table is the best way to do this.

Here are some rules to using tables

Use a pencil and a ruler to draw your table
Draw neat and straight lines
Ensure that the table is closed (connect all your lines)
Don’t cross your lines (erase any lines that stick out of the table)
Use appropriate columns and rows
Properly name each column and row (including the units of measurement in brackets)
Do not write your units in the body of your table (units belong in the header)
Always include a title

Note : If your results require calculations, clearly write each step.

Observations of the effects of light on the amount of starch in plant leaves.

blog-how-to-write-a-scientific-report-photosynthesis-results

If quantitative data was recorded, the data is often also plotted on a graph.

8. Discussion

The discussion is where you analyse and interpret your results, and identify any experimental errors or possible areas of improvements.

You should divide your discussion as follows.

1. Trend in the results

Describe the ‘trend’ in your results. That is, the relationship you observed between your independent and dependent variables.

The independent variable is the variable that you are changing in the experiment. In this experiment, it is the amount of light that the leaves are exposed to.

The dependent variable is the variable that you are measuring in the experiment, In this experiment, it is the presence of starch in the leaves.

Explain how a particular result is achieved by referring to scientific knowledge, theories and any other scientific resources you find. 2. Scientific explanation:

The presence of starch is indicated when the addition of iodine causes the leaf to turn dark purple. The results show that starch was present in the leaves that were exposed to light, while the leaves that were not exposed to light did not contain starch.

2. Scientific explanation:

Provide an explanation of the results using scientific knowledge, theories and any other scientific resources you find.

As starch is produced during photosynthesis, these results show that light plays a key role in photosynthesis.

3. Validity

Validity refers to whether or not your results are valid. This can be done by examining your variables.

VA lidity = VA riables

Identify the independent, dependent, controlled variables and the control experiment (if you have one).

The controlled variables are the variables that you keep the same across all tests e.g. the size of the leaf sample.

The control experiment is where you don’t apply an independent variable. It is untouched for the whole experiment.

Ensure that you never change more than one variable at a time!

The independent variable of the experiment was amount of light that the leaves were exposed to (the covered and uncovered geranium leaf), while the dependent variable was the presence of starch. The controlled variables were the size of the leaf sample, the duration of the experiment, the amount of time the solutions were heated, and the amount of iodine solution used.

4. Reliability

Identify how you ensured the reliability of the results.

RE liability = RE petition

Show that you repeated your experiments, cross-checked your results with other groups or collated your results with the class.

The reliability of the results was ensured by repeating the experiment 5 times and comparing results with other groups. Since other groups obtained comparable results, the results are reliable.

5. Accuracy

Accuracy should be discussed if your results are in the form of quantitative data, and there is an accepted value for the result.

Accuracy would not be discussed for our example photosynthesis experiment as qualitative data was collected, however it would if we were measuring gravity using a pendulum:

The measured value of gravity was 9.8 m/s 2 , which is in agreement with the accepted value of 9.8 m/s 2 .

6. Possible improvements

Identify any errors or risks found in the experiment and provide a method to improve it.

If there are none, then suggest new ways to improve the experimental design, and/or minimise error and risks.

blog-how-to-write-a-scientific-report-improve

Possible improvements could be made by including control experiments. For example, testing whether the iodine solution turns dark purple when added to water or methylated spirits. This would help to ensure that the purple colour observed in the experiments is due to the presence of starch in the leaves rather than impurities.

9. Conclusion

State whether the aim was achieved, and if your hypothesis was supported.

The aim of the investigation was achieved, and it was found that light is required for photosynthesis to occur. This was evidenced by the presence of starch in leaves that had been exposed to light, and the absence of starch in leaves that had been unexposed. These results support the proposed hypothesis.

Write an Essay on A Visit to a Science Fair in English | Essays for students

Visit to a science fair essay.

Education aims at holistic development of children. Several schools organize science fairs and exhibitions to enhance students’ knowledge, motivate them towards science and to make learning a fun experience. Science fair contributes to their social development and increases the skills of their presentation.

I had an occasion to visit science fair organized by my school on 28th February. All the rooms in which fair was held were decorated with charts and posters. Students had made different kinds of models using electronic gadgets, papers, cardboard and metal too. They showcased static and working models which looked extremely useful for learning and understanding various scientific concepts. I was simply astonished to see the inventive brains of the students. Models displaying the working of heart, digestive system and other organs of the body fascinated the visitors. Charts based on evolution of human beings and biodiversity were presented well. Other eye catching projects were models of solar system, volcanoes and means of transport and communication.

There were 40 exhibits with nearly 90 students involved in the event. The organizers of the fair did proper arrangements with good facilities. The whole compound was beautifully decorated. The judges appreciated the students. The principal and visitors were quite impressed with the dedication of students. Students were encouraged to develop a scientific temper. The whole event was a great success.

Overall the exhibition was informative and enlightening experience. Students learnt various scientific principles. Such science fairs help students to apply their ideas, creative thinking and learn in a unique way. I returned home quite enriched in knowledge.

DEFORESTATION ESSAY

Deforestation, in simpler terms, means the removal of forest cover or tree plantations to accommodate agricultural, industrial or urban use. It has caused a decrease in the forest cover across the world. The world is losing most of its natural resources through the process of deforestation.

Multiple factors, either of human or natural origin, cause deforestation. Natural factors include forest fires, floods and earthquakes. Human activities are mostly responsible for this process. Agriculture is the number one cause of deforestation. Increasing population demands more food to survive. Farmers are bounded to cut down trees to cultivate land. Other activities such as cattle breeding, timber extraction, mining, dam construction and infrastructure development are among the direct causes of deforestation. Trees are cut to build roads and to expand our cities to accommodate growing population.

There are many harmful effects of deforestation. Trees take carbon dioxide and release oxygen which is responsible for living. Deforestation increases the amount of carbon dioxide into the atmosphere and is the major contributor to global warming due to greenhouse effect. Deforestation is a series environmental concern since it can cause loss of biodiversity, damage to natural habitat of wildlife, disturbances in the water cycle, reduction in rainfall, soil erosion and desertification. It may lead to food insecurity in the world.

Forests are the lungs of our planet. It is responsibility of government, civil society and each and every individual to control deforestation. The government must put a ban on deforestation. And we all should do the needful to protect our trees.

How to Write a College Essay

Let QuestBridge help you with college essay writing tips. We cover what to write about, how to get feedback, and more!

The low-income lens in college essays

Students from low-income backgrounds may not realize that they have a unique perspective to present to admissions officers. If your identity has been shaped by financial difficulties and other obstacles, consider writing about these challenges in your college essays so that admissions officers understand the full context of your successes and academic accomplishments.

Bring us into your world. We want to know you. We want to know your truth.

Student challenges and extenuating circumstances

You may describe specific challenges that you have risen above in your college essays, such as:

You hold significant responsibilities in your household, such as providing care for an ill family member, babysitting siblings, or preparing family meals.
You have a part-time job to pay for school activities or household expenses.
You live with people other than your immediate family or have been in foster care.
You experienced homelessness or other temporary housing situations.
A parent has passed away or is not present in your life.
You commute a long distance to attend school.
Your family or community is not supportive of your educational goals.
You faced obstacles because English is not your first language.

Proper tone for college essays

If you choose to write about challenges in your life, be careful to avoid using overly critical or negative language when writing a college essay. This is a good opportunity to emphasize your emotional maturity and how challenges in your life have helped you grow as a person. You may compromise that impression if your tone is resentful or excessively dramatic.

College essay topic choice

Giving admissions officers a window into difficult experiences can present your story in your college application, but there are other topics that can also make for a strong essay (e.g. a favorite book, a community service project). Whichever angle you select to tell your story, highlight the most important things that have shaped and continue to shape your identity.

The writing process: brainstorm, outline, and draft

Writing a college essay can seem daunting at first, but it doesn’t have to be. Watch our webinar, Write a College Essay that Stands Out , and download our worksheet as a template and foundation to help you craft a strong college essay. This college essay format may help you write your essay in a manner that goes beyond just a chronological explanation of your life or an expansion of your resume.

Essay feedback and revisions

Ask teachers, mentors, family, or friends for feedback on your essay. Reach out well in advance of any deadlines, and give them at least two weeks to provide feedback. Ask them in person if you can, but if you cannot, send them an email. If they agree to take a look, you can send them a message with your essay. Download a sample message below.

After receiving feedback, revise! You should plan on going through a few drafts. Here are some things to keep in mind:

You do not have to incorporate all feedback. Accept what you think is most helpful.
Edits and revisions should not remove your voice or completely alter your writing style.
Pay attention to spelling, grammar, punctuation, and even formatting.
It may help to read your essay out loud to catch mistakes you might otherwise skim over.
Read your college essay from an admissions officer’s perspective.
