Often, students ask me about the best Physics extended essay topics. I think choosing an option that truly resonates with your interests but also aligns with IB’s expectations is essential. It brings me to the specifics of the IB extended essay Physics topics , which get into detailed research scopes and can challenge your analytical skills.

Possible Extended Essay Topics in IB Physics

So, what are the possible extended essay topics in IB Physics ? Here are a few options for you to consider:

• The Physics of Black Holes.
• Quantum Entanglement and its Implications.
• The Effects of Material and Thickness on Solar Cell Efficiency.
• The Acoustic Properties of Different Woods.
• Relativity in Modern GPS Systems.
• The Physics Behind Magnetic Levitation Trains.
• Fluid Dynamics in Sports.
• The Correlation Between Altitude and Boiling Points of Liquids.
• Thermoelectric Materials and their Potential in Waste Heat Recovery.
• The Harmonics of String Instruments.

Think of areas in Physics that intrigue you: Quantum mechanics? AstroPhysics? Thermodynamics? The options are numerous, but the best topics align with your passion and the IB’s expectations.

Experimental Physics Extended Essay vs. Theoretical: What’s the Difference?

Ah, the age-old debate: Experimental or Theoretical? From my experience, this decision can make or break your essay. So, let’s break it down.

• Experimental Physics . In essence, this approach is hands-on. It’s about setting up experiments, recording observations, and making inferences. If you enjoy the tangible aspects of Physics and don’t mind getting your hands dirty, this might be your calling.
• Theoretical Physics . Now, this is where things get abstract. Theoretical Physics deepens into concepts, relying heavily on mathematical models and predictions. It’s less about “doing” and more about “thinking”. If abstract ideas and critical thinking excite you, this path might be the one for you.

In conclusion, always remember to stay true to your passions while adhering to the set standards. From what I know, the path might seem challenging, but the sense of accomplishment at the end is unparalleled!

IB Physics Extended Essay: What Resources You Can Use

Taping into many resources is critical to strengthen your research and arguments. Here’s a comprehensive list that can guide you through this venture:

• Primary Textbooks . These are the backbone of your foundational knowledge. But don’t just stick to your coursebook. Check advanced-level Physics textbooks for deeper insights.
• Academic Journals . Google Scholar , JSTOR , and the American Physical Society’s journals offer up-to-date research findings and specialized knowledge.
• University Libraries . Many institutions allow the public, especially students, access to their libraries. They can be gold mines for specialized books and research papers.
• Online Platforms & Databases . You can use arXiv — a free distribution service and archive for preprints. NASA AstroPhysics Data System is also a perfect digital library portal for researchers in astronomy and Physics.
• Research Institutions & Laboratories . Some institutes allow students to access their data or even conduct experiments. Examples are CERN, Fermilab, or local universities with robust Physics departments.
• Educational Websites . Websites like Khan Academy or The Physics Classroom can elucidate complex topics.
• Software & Simulation Tools . Use COMSOL MultiPhysics for modeling and simulating experiments. PhET Interactive Simulations offers free interactive math and science simulations.
• Expert Interviews . Engaging with Physics professors, researchers, or professionals can offer unique insights. They might also point you to niche resources.
• Seminars & Workshops . Attend these, especially ones that align with your essay topic. They offer cutting-edge insights and networking opportunities.
• Your School’s Resources . Think about your school’s lab equipment, library, and, most importantly, your Physics teacher!
• Peer-Reviewed Conferences . Look for published proceedings for the latest in Physics research.
• Popular Science Books & Magazines . These can be used sparingly for general context or simply explaining complex concepts. Magazines like Scientific American or Physics Today might be helpful.

According to general IB criteria, while it’s essential to gather as much information as possible, always ensure the credibility of your sources. Cross-reference data and opt for primary over secondary sources.

The Structure of the Physics Extended Essay

Structuring your paper can make all the difference. Let’s discuss all parts of the Physics extended essay to ensure clarity and coherence.

1. The Informative Abstract

Venturing forward, you’d step into the abstract. Think of this as your elevator pitch, where you have around 300 words to present the crux of your research. Start by briefly explaining the purpose of your essay.

2. The All-Important Introduction

The introduction is your gateway to captivate the reader. Set the stage by introducing your topic and providing context. Why is it important? What real-world implications does it have? How does it tie into the larger world of Physics?

3. Methodology and Approach

Detail out the methods you’ve employed. Clarity is vital, whether it’s an experimental setup or a theoretical analysis. Describe your approach, any equipment used, variables considered, and how you collected data.

4. To the Body

It’s the heart of your essay. Analyze your findings, relate them to existing theories, and critically evaluate any discrepancies or anomalies. Break down complex concepts, ensuring they’re accessible to the reader. Use diagrams, graphs, or tables if they aid in understanding.

5. Conclusions and Reflections

Summarize your findings, reiterating their significance in the broader context of Physics. Reflect upon the entire research process, discussing your challenges and what you learned from them. Highlight potential areas for further research or unanswered questions that arose.

6. References and Bibliography

Every piece of information, data, or idea that isn’t original to you needs to be cited. Adhere to the citation style preferred by the IB and ensure consistency throughout.

Writing the Perfect Experimental Physics Extended Essay

Ah, the realm of experimental Physics extended essay. Many students assume this is the most challenging assignment , but this is only sometimes the case. With the right approach, you can quickly reveal your topic and get the highest grade, so do not be afraid to experiment.

What Makes an Experimental Physics Extended Essay Stand Out?

Based on my experience, the most outstanding essays consistently demonstrate these characteristics:

• They don’t just regurgitate known facts. They take risks, push novel ideas, or offer a fresh perspective on classic experiments.
• It’s not just about noting observations but explaining why specific results were obtained, possibly linking to underlying Physics principles.
• A standout essay meticulously details the experiment setup, ensuring reproducibility. Every step, from equipment calibration to data collection, is clearly articulated.
• Beyond presenting results, these essays interpret data critically, drawing meaningful conclusions and suggesting further research areas.

Remember that the best essays often link findings to real-world applications or implications, showing a broader understanding of Physics in our daily lives.

Tips for a Successful Physics Extended Essay

Throughout my path as an IB tutor, I’ve picked up a few tricks of the trade that I believe can improve any paper:

• Start Early . Physics, being a comprehensive subject, demands time for research, experimentation (if you’re doing an experimental essay), and analysis.
• Pick a Manageable Topic . Getting into highly complex areas is tempting, but remember that depth trumps breadth. 
• Align with Your Interests . Your enthusiasm will shine through in your writing. Choose a topic you’re genuinely curious about. 
• Prioritize Your Research Question . It should be clear, focused, and researchable within the word limit. Avoid overly broad or vague questions.
• Use Varied Resources . While textbooks are a good starting point, venture into academic journals, online databases, and expert interviews to gather diverse insights.
• Stick to the IB Rubric . Familiarize yourself with the IB Physics extended essay criteria . This rubric will be your guiding light, ensuring you hit all the necessary points.
• Draft, Revise, Repeat . Your first draft is unlikely to be your final one. Write, take a break, return with fresh eyes, revise, and repeat the cycle.
• Maintain Academic Integrity . Cite all sources diligently. Plagiarism is a strict no-no in the IB world.
• Understand the Theory . Even if you’re focusing on an experiment, grounding your observations in theoretical concepts is crucial. It shows a holistic understanding of the topic.
• Maintain a Consistent Structure . Introduction, research question, body, analysis, conclusion, and references — maintaining this flow aids in readability and coherence.

Over the years, I’ve seen students get lost in the vastness of their chosen subjects, but with a straightforward question, you can remain focused. Lastly, avoid straying from the IB extended essay Physics guidelines. They’re there for a reason, and adhering to them can significantly boost your score.

So, writing the Physics extended essay is no small feat, but with the right approach and a sprinkle of dedication, it’s an enriching experience. Follow the guidelines, choose your topic wisely, and structure your essay well, and you’ll be on the path to success. Best of luck to you!

The Complete IB Extended Essay Guide: Examples, Topics, and Ideas

International Baccalaureate (IB)

IB students around the globe fear writing the Extended Essay, but it doesn't have to be a source of stress! In this article, I'll get you excited about writing your Extended Essay and provide you with the resources you need to get an A on it.

If you're reading this article, I'm going to assume you're an IB student getting ready to write your Extended Essay. If you're looking at this as a potential future IB student, I recommend reading our introductory IB articles first, including our guide to what the IB program is and our full coverage of the IB curriculum .

IB Extended Essay: Why Should You Trust My Advice?

I myself am a recipient of an IB Diploma, and I happened to receive an A on my IB Extended Essay. Don't believe me? The proof is in the IBO pudding:

If you're confused by what this report means, EE is short for Extended Essay , and English A1 is the subject that my Extended Essay topic coordinated with. In layman's terms, my IB Diploma was graded in May 2010, I wrote my Extended Essay in the English A1 category, and I received an A grade on it.

What Is the Extended Essay in the IB Diploma Programme?

The IB Extended Essay, or EE , is a mini-thesis you write under the supervision of an IB advisor (an IB teacher at your school), which counts toward your IB Diploma (learn more about the major IB Diploma requirements in our guide) . I will explain exactly how the EE affects your Diploma later in this article.

For the Extended Essay, you will choose a research question as a topic, conduct the research independently, then write an essay on your findings . The essay itself is a long one—although there's a cap of 4,000 words, most successful essays get very close to this limit.

Keep in mind that the IB requires this essay to be a "formal piece of academic writing," meaning you'll have to do outside research and cite additional sources.

The IB Extended Essay must include the following:

• A title page
• Contents page
• Introduction
• Body of the essay
• References and bibliography

Additionally, your research topic must fall into one of the six approved DP categories , or IB subject groups, which are as follows:

• Group 1: Studies in Language and Literature
• Group 2: Language Acquisition
• Group 3: Individuals and Societies
• Group 4: Sciences
• Group 5: Mathematics
• Group 6: The Arts

Once you figure out your category and have identified a potential research topic, it's time to pick your advisor, who is normally an IB teacher at your school (though you can also find one online ). This person will help direct your research, and they'll conduct the reflection sessions you'll have to do as part of your Extended Essay.

As of 2018, the IB requires a "reflection process" as part of your EE supervision process. To fulfill this requirement, you have to meet at least three times with your supervisor in what the IB calls "reflection sessions." These meetings are not only mandatory but are also part of the formal assessment of the EE and your research methods.

According to the IB, the purpose of these meetings is to "provide an opportunity for students to reflect on their engagement with the research process." Basically, these meetings give your supervisor the opportunity to offer feedback, push you to think differently, and encourage you to evaluate your research process.

The final reflection session is called the viva voce, and it's a short 10- to 15-minute interview between you and your advisor. This happens at the very end of the EE process, and it's designed to help your advisor write their report, which factors into your EE grade.

Here are the topics covered in your viva voce :

• A check on plagiarism and malpractice
• Your reflection on your project's successes and difficulties
• Your reflection on what you've learned during the EE process

Your completed Extended Essay, along with your supervisor's report, will then be sent to the IB to be graded. We'll cover the assessment criteria in just a moment.

We'll help you learn how to have those "lightbulb" moments...even on test day!  

What Should You Write About in Your IB Extended Essay?

You can technically write about anything, so long as it falls within one of the approved categories listed above.

It's best to choose a topic that matches one of the IB courses , (such as Theatre, Film, Spanish, French, Math, Biology, etc.), which shouldn't be difficult because there are so many class subjects.

Here is a range of sample topics with the attached extended essay:

• Biology: The Effect of Age and Gender on the Photoreceptor Cells in the Human Retina
• Chemistry: How Does Reflux Time Affect the Yield and Purity of Ethyl Aminobenzoate (Benzocaine), and How Effective is Recrystallisation as a Purification Technique for This Compound?
• English: An Exploration of Jane Austen's Use of the Outdoors in Emma
• Geography: The Effect of Location on the Educational Attainment of Indigenous Secondary Students in Queensland, Australia
• Math: Alhazen's Billiard Problem
• Visual Arts: Can Luc Tuymans Be Classified as a Political Painter?

You can see from how varied the topics are that you have a lot of freedom when it comes to picking a topic . So how do you pick when the options are limitless?

How to Write a Stellar IB Extended Essay: 6 Essential Tips

Below are six key tips to keep in mind as you work on your Extended Essay for the IB DP. Follow these and you're sure to get an A!

#1: Write About Something You Enjoy

You can't expect to write a compelling essay if you're not a fan of the topic on which you're writing. For example, I just love British theatre and ended up writing my Extended Essay on a revolution in post-WWII British theatre. (Yes, I'm definitely a #TheatreNerd.)

I really encourage anyone who pursues an IB Diploma to take the Extended Essay seriously. I was fortunate enough to receive a full-tuition merit scholarship to USC's School of Dramatic Arts program. In my interview for the scholarship, I spoke passionately about my Extended Essay; thus, I genuinely think my Extended Essay helped me get my scholarship.

But how do you find a topic you're passionate about? Start by thinking about which classes you enjoy the most and why . Do you like math classes because you like to solve problems? Or do you enjoy English because you like to analyze literary texts?

Keep in mind that there's no right or wrong answer when it comes to choosing your Extended Essay topic. You're not more likely to get high marks because you're writing about science, just like you're not doomed to failure because you've chosen to tackle the social sciences. The quality of what you produce—not the field you choose to research within—will determine your grade.

Once you've figured out your category, you should brainstorm more specific topics by putting pen to paper . What was your favorite chapter you learned in that class? Was it astrophysics or mechanics? What did you like about that specific chapter? Is there something you want to learn more about? I recommend spending a few hours on this type of brainstorming.

One last note: if you're truly stumped on what to research, pick a topic that will help you in your future major or career . That way you can use your Extended Essay as a talking point in your college essays (and it will prepare you for your studies to come too!).

#2: Select a Topic That Is Neither Too Broad nor Too Narrow

There's a fine line between broad and narrow. You need to write about something specific, but not so specific that you can't write 4,000 words on it.

You can't write about WWII because that would be a book's worth of material. You also don't want to write about what type of soup prisoners of war received behind enemy lines, because you probably won’t be able to come up with 4,000 words of material about it. However, you could possibly write about how the conditions in German POW camps—and the rations provided—were directly affected by the Nazis' successes and failures on the front, including the use of captured factories and prison labor in Eastern Europe to increase production. WWII military history might be a little overdone, but you get my point.

If you're really stuck trying to pinpoint a not-too-broad-or-too-narrow topic, I suggest trying to brainstorm a topic that uses a comparison. Once you begin looking through the list of sample essays below, you'll notice that many use comparisons to formulate their main arguments.

I also used a comparison in my EE, contrasting Harold Pinter's Party Time with John Osborne's Look Back in Anger in order to show a transition in British theatre. Topics with comparisons of two to three plays, books, and so on tend to be the sweet spot. You can analyze each item and then compare them with one another after doing some in-depth analysis of each individually. The ways these items compare and contrast will end up forming the thesis of your essay!

When choosing a comparative topic, the key is that the comparison should be significant. I compared two plays to illustrate the transition in British theatre, but you could compare the ways different regional dialects affect people's job prospects or how different temperatures may or may not affect the mating patterns of lightning bugs. The point here is that comparisons not only help you limit your topic, but they also help you build your argument.

Comparisons are not the only way to get a grade-A EE, though. If after brainstorming, you pick a non-comparison-based topic and are still unsure whether your topic is too broad or narrow, spend about 30 minutes doing some basic research and see how much material is out there.

If there are more than 1,000 books, articles, or documentaries out there on that exact topic, it may be too broad. But if there are only two books that have any connection to your topic, it may be too narrow. If you're still unsure, ask your advisor—it's what they're there for! Speaking of advisors...

Don't get stuck with a narrow topic!

#3: Choose an Advisor Who Is Familiar With Your Topic

If you're not certain of who you would like to be your advisor, create a list of your top three choices. Next, write down the pros and cons of each possibility (I know this sounds tedious, but it really helps!).

For example, Mr. Green is my favorite teacher and we get along really well, but he teaches English. For my EE, I want to conduct an experiment that compares the efficiency of American electric cars with foreign electric cars.

I had Ms. White a year ago. She teaches physics and enjoyed having me in her class. Unlike Mr. Green, Ms. White could help me design my experiment.

Based on my topic and what I need from my advisor, Ms. White would be a better fit for me than would Mr. Green (even though I like him a lot).

The moral of my story is this: do not just ask your favorite teacher to be your advisor . They might be a hindrance to you if they teach another subject. For example, I would not recommend asking your biology teacher to guide you in writing an English literature-based EE.

There can, of course, be exceptions to this rule. If you have a teacher who's passionate and knowledgeable about your topic (as my English teacher was about my theatre topic), you could ask that instructor. Consider all your options before you do this. There was no theatre teacher at my high school, so I couldn't find a theatre-specific advisor, but I chose the next best thing.

Before you approach a teacher to serve as your advisor, check with your high school to see what requirements they have for this process. Some IB high schools require your IB Extended Essay advisor to sign an Agreement Form , for instance.

Make sure that you ask your IB coordinator whether there is any required paperwork to fill out. If your school needs a specific form signed, bring it with you when you ask your teacher to be your EE advisor.

#4: Pick an Advisor Who Will Push You to Be Your Best

Some teachers might just take on students because they have to and aren't very passionate about reading drafts, only giving you minimal feedback. Choose a teacher who will take the time to read several drafts of your essay and give you extensive notes. I would not have gotten my A without being pushed to make my Extended Essay draft better.

Ask a teacher that you have experience with through class or an extracurricular activity. Do not ask a teacher that you have absolutely no connection to. If a teacher already knows you, that means they already know your strengths and weaknesses, so they know what to look for, where you need to improve, and how to encourage your best work.

Also, don't forget that your supervisor's assessment is part of your overall EE score . If you're meeting with someone who pushes you to do better—and you actually take their advice—they'll have more impressive things to say about you than a supervisor who doesn't know you well and isn't heavily involved in your research process.

Be aware that the IB only allows advisors to make suggestions and give constructive criticism. Your teacher cannot actually help you write your EE. The IB recommends that the supervisor spends approximately two to three hours in total with the candidate discussing the EE.

#5: Make Sure Your Essay Has a Clear Structure and Flow

The IB likes structure. Your EE needs a clear introduction (which should be one to two double-spaced pages), research question/focus (i.e., what you're investigating), a body, and a conclusion (about one double-spaced page). An essay with unclear organization will be graded poorly.

The body of your EE should make up the bulk of the essay. It should be about eight to 18 pages long (again, depending on your topic). Your body can be split into multiple parts. For example, if you were doing a comparison, you might have one third of your body as Novel A Analysis, another third as Novel B Analysis, and the final third as your comparison of Novels A and B.

If you're conducting an experiment or analyzing data, such as in this EE , your EE body should have a clear structure that aligns with the scientific method ; you should state the research question, discuss your method, present the data, analyze the data, explain any uncertainties, and draw a conclusion and/or evaluate the success of the experiment.

#6: Start Writing Sooner Rather Than Later!

You will not be able to crank out a 4,000-word essay in just a week and get an A on it. You'll be reading many, many articles (and, depending on your topic, possibly books and plays as well!). As such, it's imperative that you start your research as soon as possible.

Each school has a slightly different deadline for the Extended Essay. Some schools want them as soon as November of your senior year; others will take them as late as February. Your school will tell you what your deadline is. If they haven't mentioned it by February of your junior year, ask your IB coordinator about it.

Some high schools will provide you with a timeline of when you need to come up with a topic, when you need to meet with your advisor, and when certain drafts are due. Not all schools do this. Ask your IB coordinator if you are unsure whether you are on a specific timeline.

Below is my recommended EE timeline. While it's earlier than most schools, it'll save you a ton of heartache (trust me, I remember how hard this process was!):

• January/February of Junior Year: Come up with your final research topic (or at least your top three options).
• February of Junior Year: Approach a teacher about being your EE advisor. If they decline, keep asking others until you find one. See my notes above on how to pick an EE advisor.
• April/May of Junior Year: Submit an outline of your EE and a bibliography of potential research sources (I recommend at least seven to 10) to your EE advisor. Meet with your EE advisor to discuss your outline.
• Summer Between Junior and Senior Year: Complete your first full draft over the summer between your junior and senior year. I know, I know—no one wants to work during the summer, but trust me—this will save you so much stress come fall when you are busy with college applications and other internal assessments for your IB classes. You will want to have this first full draft done because you will want to complete a couple of draft cycles as you likely won't be able to get everything you want to say into 4,000 articulate words on the first attempt. Try to get this first draft into the best possible shape so you don't have to work on too many revisions during the school year on top of your homework, college applications, and extracurriculars.
• August/September of Senior Year: Turn in your first draft of your EE to your advisor and receive feedback. Work on incorporating their feedback into your essay. If they have a lot of suggestions for improvement, ask if they will read one more draft before the final draft.
• September/October of Senior Year: Submit the second draft of your EE to your advisor (if necessary) and look at their feedback. Work on creating the best possible final draft.
• November-February of Senior Year: Schedule your viva voce. Submit two copies of your final draft to your school to be sent off to the IB. You likely will not get your grade until after you graduate.

Remember that in the middle of these milestones, you'll need to schedule two other reflection sessions with your advisor . (Your teachers will actually take notes on these sessions on a form like this one , which then gets submitted to the IB.)

I recommend doing them when you get feedback on your drafts, but these meetings will ultimately be up to your supervisor. Just don't forget to do them!

The early bird DOES get the worm!

How Is the IB Extended Essay Graded?

Extended Essays are graded by examiners appointed by the IB on a scale of 0 to 34 . You'll be graded on five criteria, each with its own set of points. You can learn more about how EE scoring works by reading the IB guide to extended essays .

• Criterion A: Focus and Method (6 points maximum)
• Criterion B: Knowledge and Understanding (6 points maximum)
• Criterion C: Critical Thinking (12 points maximum)
• Criterion D: Presentation (4 points maximum)
• Criterion E: Engagement (6 points maximum)

How well you do on each of these criteria will determine the final letter grade you get for your EE. You must earn at least a D to be eligible to receive your IB Diploma.

Although each criterion has a point value, the IB explicitly states that graders are not converting point totals into grades; instead, they're using qualitative grade descriptors to determine the final grade of your Extended Essay . Grade descriptors are on pages 102-103 of this document .

Here's a rough estimate of how these different point values translate to letter grades based on previous scoring methods for the EE. This is just an estimate —you should read and understand the grade descriptors so you know exactly what the scorers are looking for.

Here is the breakdown of EE scores (from the May 2021 bulletin):

How Does the Extended Essay Grade Affect Your IB Diploma?

The Extended Essay grade is combined with your TOK (Theory of Knowledge) grade to determine how many points you get toward your IB Diploma.

To learn about Theory of Knowledge or how many points you need to receive an IB Diploma, read our complete guide to the IB program and our guide to the IB Diploma requirements .

This diagram shows how the two scores are combined to determine how many points you receive for your IB diploma (3 being the most, 0 being the least). In order to get your IB Diploma, you have to earn 24 points across both categories (the TOK and EE). The highest score anyone can earn is 45 points.

Let's say you get an A on your EE and a B on TOK. You will get 3 points toward your Diploma. As of 2014, a student who scores an E on either the extended essay or TOK essay will not be eligible to receive an IB Diploma .

Prior to the class of 2010, a Diploma candidate could receive a failing grade in either the Extended Essay or Theory of Knowledge and still be awarded a Diploma, but this is no longer true.

Figuring out how you're assessed can be a little tricky. Luckily, the IB breaks everything down here in this document . (The assessment information begins on page 219.)

A Primer on the IB Extended Essay in Physics

The International Baccalaureate Diploma Programme (IBDP), with its high academic standards, has three core components, i.e., EE, CAS, and TOK. Each component has its own challenges. IB Extended Essay in Physics (EE) is a 4,000-word essay-based project that allows students to delve deep into a topic of their choice within the parameters of the IB syllabus.

For those who are passionate about the physical realm of the world, the IB extended essay in Physics provides an opportunity to make an in-depth exploration of a complex physical scientific phenomenon. The following article offers a comprehensive primer on the IB extended essay in physics so that students can streamline their journey without any hassle or bewilderment.

• Choosing a suitable physics topic

The first and foremost step in this research project on physics is selecting a topic that genuinely interests you. This will keep you motivated throughout the process. It is imperative to choose a topic of your choice, as you will be spending a sufficient amount of time on this particular topic. As physics, as a discipline, comes with a vast variety of topics, it is important to take some time to explore topics that pique your interest.

The key to selecting a suitable topic lies in maintaining a balance between interest and the availability of research and experimental resources. For example, if you are choosing to base your study on MRI scanning in the field of quantum mechanics, you should have relevant equipment to conduct your experiment and research.

• Formulating a focused research question

After selecting a suitable topic that is also practically feasible, the next step is to formulate a single, focused research question that will become the basis for your entire study. Your research question should be broad enough to allow research and specific enough to be unique and new. A well-drafted research question further helps in formulating clear and concise arguments. With an ambiguous research question, the coherency of the entire essay might be compromised.

• Conducting experiments and research

This is an action stage. After formulating a research question, the next step is to conduct relevant research and experiments to ensure the authenticity of the extended essay. Gathering information involves reading relevant books, academic journals, scholarly articles, online databases, and interviews with experts in the field. The more you develop your research portfolio, the more diverse your extended essay will be. Research is important to collect evidence for your specific research question and thesis statement.

If your research requires conducting experiments in a laboratory, you should plan and execute them properly and meticulously. You must be aware of the proper methodologies, safety protocols, and control variables. The experiments should be conducted in accordance with established rules and regulations and should involve the collection and recording of empirical data with precision.

• Structuring Your IB Physics Extended Essay

Presenting the subject matter is as important as the subject matter. Thus, the structure of your extended essay is vital for its presentation. It should follow an unambiguous and logical format.

• Title Page : The title page should include the title of your essay, your full name, the IB candidate number, and the date.
• Abstract : A clear and concise summary of your research question and the main argument, i.e., thesis statement, methodologies used, key findings, and conclusion, is to be stated here.
• Table of Contents : This is the index page where all sections and sub-sections with corresponding page numbers should be written.
• Introduction : Under this, your thesis statement for your particular research question should be articulated clearly. This section should also include the historical background and relevance of your research question. You should also mention the significance of choosing a particular research topic.
• Literature Review : A review of existing literature should be stated under this heading, which will demonstrate your understanding of the field.
• Methodology : A detailed description of all the techniques and methodologies employed in experiments and research. For example, what data collection methods and analytical techniques are used will be mentioned.
• Results : Articulating your interpretations and analysis by presenting them in a well-organised manner. Students should include visual representations, such as bar graphs and pie charts, to make their extended essay impressive.
• Discussion : This section states the interpretation of your results, the analysis of their significance, and discusses how they relate to a particular research question.
• Conclusion : A brief summary of your findings and how they relate to your research question is to be stated here.
• References : A list of all the sources to which you have referred while conducting your research. Academic style should be used while referencing and citing.

Tips for Success

• Early bird approach: The Extended Essay requires months of planning and execution, so it’s imperative to begin early in order to avoid any last-minute hassles. If anything goes wrong early on, you can begin again, which becomes difficult when you already started late.
• Seek guidance: Keep in touch with your IB supervisors for guidance and criticism. They know what is expected in an extended essay, so you can live up to those expectations under their guidance.
• Stay organised: Organise your research and writing process by making proper notes and a plan chart.
• Edit and proofread: After finishing your first draft, take time to review your extended essay. This will help to remove ambiguity and inconsistency in your extended essay. See for grammatical errors, clarity of arguments, etc.

Pro Tip: Take a little break before you start reviewing your first draft. This will give you a fresh perspective on your research.

• Stay True to Your Research Question: Throughout the essay, you should ensure that your entire essay is relevant to your research question.

Conclusion The IB Extended Essay in Physics is a challenging yet rewarding endeavour. As it explores the physical realm of our known universe, there are ever-so-many intricacies involved. It exposes students to the highly sought-after research skills required in high-level education. This independent research helps students develop a critical and logical way of seeing things.
