Scientific Method Worksheets: Free and For All Ages!

Need some scientific method worksheets for your kids?

Wouldn’t hurt if they were free and easy to print?

I got you, Homeschool Mama!

At the bottom of this post you will find 7 Scientific Method Worksheets in a free printable pack! And they can be used for early elementary students to about 7th grade.

They will easily slide into any lesson plan as you teach the scientific method steps!

The 7 Steps Of The Scientific Method

There seem to be several variations out there, but let’s pause and nail down the basics of the scientific method. 

Here is a quick review if you need a brush-up:

1. Make An Observation

The first step is to look at the world around you. What do you notice? What interests you? What are you curious about?

Things outside? In the kitchen?

What do you not understand or have questions about? What would you like to know more about?

Example : My mom waters her flowers every day, but she doesn’t water the grass. But the grass and flowers look to be equally healthy. 

2. Ask A Question

Work with your young scientists to develop a question from their observations.

Example : Do flowers really need to be watered more than the rain that waters the grass? Is my mom just wasting her time?

****Some science curriculum will teach that you should have a step of research at this point in the scientific method. Feel free to do that with older kids to look up background information and enrich your experiment. Younger kids may feel that this step stifles their curiosity or slows down their science learning energy. 

3. Come Up With A Hypothesis (Prediction)

Help your student to make a hypothesis (kids usually love saying this word!) about what they think is the answer to their question. 

Depending on the age of the child, tell them it is an educated guess or a prediction.

Example : I predict that the flowers will do just fine without extra water from my mom.

4. Test The Prediction (Do An Experiment!)

Obviously, this is the fun part of science. 

Kids get to put the books and pencils aside and start building their own science experiments! 

Your students will likely need help with their experimental design. Definitely dig in and help them figure out the best way to test their hypothesis.

For older kids, you might introduce the concepts of independent variables and control group vs. experimental group.

Example : I stop watering the flowers for 1 month while keeping a daily photographic record of the flowers and grass’ health/appearance.

I also keep a data table to monitor rainfall and temperature.

As a control group, I water only one flower regularly as my mother did. 

5. Analyze Results

Now that the experiment is over, it’s time to sit down and do some data analysis.

Which is fancy science talk for looking closely at the results of your experiment. Are there any patterns or trends in your data collection? 

Did anything unexpected happen? What did the experiment show you?

Example : All my flowers are turning brown, but the grass looks about the same. The charts and pictures during the experiment show me that it only took 3 days to start noticing wilting in the flowers. The flowers perked up after a rain, but they would start to wilt again a few days later.  My control flower (that I watered regularly) looks as health as it did on day 1.

6. Compare Results To Your Hypothesis

Look at the results of your experiment and compare them to your prediction.

Was your hypothesis correct or incorrect?

Example : My hypothesis was incorrect. The flowers did not thrive on the same amount of water that the grass gets. 

7. Make a Conclusion

At the end of the experiment, you must write out what you can conclude from your experiment. Older kids should be encouraged to follow up with further questions they have from the results of the experiment.

Example : I conclude that the grass in my yard does not need as much water as the flowers.

As a question for further study, I would like to know if this is only true of the type of flowers in my garden. Would other flowers respond the same way? Why do wild flowers seem so healthy without any human help?

7 Free Scientific Method Worksheets!

Now that we’ve brushed up on our knowledge of the scientific method, let’s dive into these worksheets!

This worksheet is actually a colorful poster displaying all the steps of the scientific method for your students!

I recommend printing it on cardstock or laminating it.

It’s the perfect thing to have displayed in your homeschool or science classes.

This is a follow-up student worksheet that matches the above poster.

The boxes help your student hit all of the most important steps as they work through their own experiments – without being too overwhelming.

I love this science worksheet for simple experiments with first grade and 2nd grade students.

Writing out or drawing every detail as they go along, may seem overwhelming.

This style of worksheet is a fun way of bringing the scientific method down to their level!

This worksheet option goes a step further.

It allows young students to walk through the steps of the scientific method by drawing pictures or writing small phrases.

This can be a great way to make science more approachable!

This worksheet is more appropriate for 3rd grade and up. 

The steps are still slightly abbreviated, but the child is expected to write out sentences. 

This worksheet is perfect for a more detailed and thorough approach.

The student has space for thinking through and writing out their experiment steps. 

Science teachers can get a quick overview of how the student is doing.

This last worksheet is clearly for the older student, such as 5th grade and up.

Writing out full sentences and recording their work is more appropriate at this age. 

The worksheet still provides the structure of showing each of the steps.

****This sheet does have a space for hypothesis and prediction. I left that for the older students because some lessons do teach them as separate things. The hypothesis is the answer to your question, and the prediction is what you think will happen in the experiment. Using my flower/grass experiment from earlier, let me give you an example. Hypothesis : Flowers do not need more water than grass. Prediction : The flowers and grass will look healthy after 1 month of only rainwater.

You might be wondering why there wasn’t a “typical” worksheet in this post.

Such as a cut and paste, crossword, or match with an answer key. 

The reason is that hands-on activities are the best way to teach the scientific method – not worksheets. Kids will learn science and *remember* it more when they get to DO it.

And as you know, that’s actually true of most things.

I hope these worksheets bless your students and you enjoy exploring the world around you!

What are the steps to the scientific method? (Plus, a free worksheet!)

Krystal DeVille

Updated on: October 29, 2020

The scientific method is a 6 step method scientists use to conduct experiments and learn about the world around them.

It is essentially a framework on how to ask a question and then answer it.

We all make observations and ask questions about the world around us. Then, we make a guess (or hypothesis) about what we think the answer is. The scientific method is the process to determine if your hypothesis is correct.

Whether you are making slime at home, growing seeds, or conducting a much more elaborate experiment, you can use this free scientific method worksheet to guide your process!

Implementing the scientific method in your at home & fun science experiments, is a great way to reinforce logic and problem solving skills.

There are 6 steps to the scientific method, plus one feedback step:

• Make an Observation
• Ask a Question
• Form a Hypothesis
• Test Your Hypothesis
• Observe Results
• Form Conclusion

The “7th” step to the scientific method is the feedback step, where you make an iteration or ask a new question to test. This step loops back to the first step of your next experiment

Now, let’s dive into each step of the scientific method with an example!

In this example, we’ll walk through the scientific method in an experiment where you’re testing how seeds may grow in different types of soil.

Step 1: Make an Observation

We all notice things occurring around us! This first step of starting your experiment.

In this example, you notice that the flowers are growing differently around the yard. In some parts of the yard, the flowers are already blossoming! While in other parts, they’re still struggling to grow.

This is also when you may do some initial research. You notice they get different amounts of sunlight and that one area of your yard is much rockier. In this step, record your observations and research.

Step 2: Ask a Question

Next, ask your question.

In this experiment, we’re trying to understand why the flowers grow at different rates around the yard. Why are some big and others small?

Step 3: Form a Hypothesis

In the next step, you create your hypothesis. A hypothesis is an assumption or idea that you can test in an experiment or study.

It’s important to emphasize that the hypothesis is something you can test.

When creating your hypothesis, use your research and observations to form your assumption.

In this example, you had observed that the soil was very different across the yard. In some places it was very sandy, other places very rocky. You form your hypothesis off this assumption that different soils cause the flowers to grow better.

Step 4: Experiment

Next, it’s time for your experiment! Use the free worksheet to list each step of your experiment and the materials that you need.

The experiment should be focused on either concluding your hypothesis is true, or it is not.

In this experiment, we decide to fill jars with 3 different types of soil samples collected around the yard. In each jar, we place a seed and then set them in the same place and water them at the same time every day.

For older students, during the experimental step, you can also list your controlled variables. What needs to stay constant in order to test your hypothesis?

In this experiment, water, sun, and the type of seed are our controlled (or constant variables. The dirt is our independent variable – the thing that we are testing.

You can download this great worksheet too on understanding the different variables in a science experiment!

Step 5: Results

Next, observe and record your results.

In our experiment, we watched the flowers grow and recorded how each flower grew different day to day.

We may want to note which flower sprouted first, which one bloomed first, and which one lived longest.

We make notes about all of our observations and results in our worksheet or notebook.

Step 6: Conclusion

Lastly, use your results and observations to determine if your hypothesis was supported.

A conclusion should center around your hypothesis. Was your hypothesis supported or not supported?

And remember to explain that a wrong hypothesis is not a bad experiment .

It’s important to teach about and avoid research bias. An experiment is about testing a hypothesis, not proving it. An experiment that shows that a hypothesis is not true is just as good as the one that shows a hypothesis is correct!

Step 7: Iterate (Feedback Step)

Testing your first hypothesis doesn’t mean your experiment is over!

During your experiment, you may make other observations or want to test other variables. The last step is your feedback step, where you iterate or repeat.

This loops back into the first steps of a new experiment where you make an observation and ask a question, and then start a new experiment using the steps of the scientific method.

History of the Scientific Method

Historically speaking, no specific person can be credited with designing the Scientific Method as we know it today. There isn’t even an “Ultimate Scientific Method” that is the best and most tried system.

Every scientific process works well as long as it starts with curiosity, can be tested through an experiment, and leads to a conclusive observation. It stands as a logical, rational, and problem-solving type of method applicable to a multitude of fields.

That’s not always the fun answer, so let’s take a second to credit those that did historically advance the Scientific Method. The Scientific Method has a rich history that has progressed and evolved from geniuses such as Aristotle, Al-Biruni, and Isaac Newton.

Science was traditionally categorized into an overarching branch mixed with Philosophy and Technology. It wasn’t until the Scientific Revolution that it became its own independent field of study.

The Scientific Revolution started in the 1500s and made immaculate breakthroughs to develop the emergence of modern science.

With the monumental advancements from Enlightenment scientists such as Galileo Galilei, Francis Bacon, and Rene Descartes in changing variables and recording their process.

The scientific method made great gains in the 16th century and 17th centuries. Even then, the “Scientific Method” as a term did not gain much headway until the 20th century, but the design itself was put into words for future generations to expand on.

Wrapping Up Scientific Method

Regardless of the experiment – and countless others to use, some even on this very same website – the importance of the Scientific Method for kids is limitless. When using this structure, you provide your child with the foundation of a logical and rational way to solve any problem.

Science doesn’t always require using safety goggles or a microscope; it can be utilized with anything. If you’re curious and have a question, then apply this method!

Tell you what, how about you use this as an experiment in and of itself. See if your child or children enjoy using the Scientific Method to conduct their own experiments.

Make a hypothesis: Will they enjoy it or not? When you come to the conclusion that they love it and are only benefiting from it, then share those thoughts here with us! Until then, have fun experimenting!

Photosynthesis Amoeba Sisters Video Response Sheet

What educators are saying

Also included in.

Description

Photosynthesis Video Response Worksheet to use with the Amoeba Sisters Video on YouTube.

This resource goes with the *updated* Amoeba Sisters Photosynthesis video (not the old video). A link and QR code is provided to the correct video so there is no confusion between you and your students.

This resource follows along with the video and asks several kinds of comprehension questions. Use this as a supplement to your notes.

In this resource you will get:

• Student handout (2 pages) word document and PDF
• Teacher Key word document and PDF

How I use this is my classroom

Photosynthesis is such a tricky topic to teach and for students to learn. I created this video worksheet to go along with the Amoeba Sister’s Photosynthesis video- but I don’t use it in the same way I typically do.

Typically, I would put the video on and have students follow along while they fill out the worksheet. I find this is WAY TOO OVERWHELMING for most students for this challenging topic. So instead, I frequently pause the video to discuss and make sure students are getting the right information. It takes a lot longer- maybe two or more times longer to do it this way- but at least students don’t come away frustrated from the assignment. I think it is best for students to at least have some knowledge of photosynthesis before doing this assignment.

Another way you might use this assignment is after you have given notes and discussed the assignment you could give the video/worksheet as small group work or as homework . I find that students REALLY need to pause this video to get the most out of it and giving them the ability to pause at the own pace can very helpful.

In any way you decide to use this worksheet, I am sure you will make it work best for your learners and your classroom!
