Teaching the Scientific Method & a Free Printable

Earlier in July, I posted a terrific article (if I do say so myself) on the science behind slime and all the cool lessons and activities you could do to teach real science concepts like viscosity and non-Newtonian fluids. Buried in that post was this printable, and I was afraid it might get lost in the sliminess.

So, below is the section from that post explaining what the scientific method is and how it can guide any experiment you do or answer (almost) any question you and your kids have about a sciencey subject.

I love the scientific method, and when I was a high school science teacher, I used a paper airplane lab to teach the steps.

The Scientific Method Steps

The scientific method is the backbone of all science. It's the general set of steps that all scientists and researchers follow in order to learn new stuff about the world, although it is fluid and flexible and sometimes done in a different order. But essentially, here's what happens:

• Observe a situation.
• Identify a problem or question. What do you want to learn or answer?
• Research the problem or question, possible causes and factors that could affect it. What do you already know or can you learn from others' work?
• Write a hypothesis or educated guess based on the information you have. What do you predict will happen?
• Create an experiment to test the hypothesis. Use this opportunity to talk about variables and trials (explained below).
• Observe and analyze the results. What happened?
• Draw conclusions . What did you learn? Was your hypothesis proved or disproved?
• Report the results of your experiment.

Then you start over, tweaking your hypothesis given the new information that you have. You might repeat this process four or five times or even more depending on your experiment and variables.

The steps of the scientific method are typically done in order, but after you get to the end, you may come back to step 4 and create a new hypothesis without additional research. Or you may come back to step 5 and create a new experiment to retest your existing hypothesis/prediction. The steps are a guideline but there is room to jump around a bit and continue your scientific investigation.

Free scientific method worksheet

I created this free scientific method printable resource that you can grab and fill out with your kids. It's appropriate for all grade levels, although probably best for elementary students as older kids might find the font a bit juvenile. (We all know how cool they are.)

Hint: a great way to write the question in the beginning is to follow this format:

What effect will ___________ have on___________?

Variables are things that change during an experiment. Part of designing an effective experiment is identifying and manipulating the variables. Independent variables are variables that you can control, such as the amount of glue or the amount of water. Dependent variables are variables that change as the independent variables change, such as the stickiness of the slime you create. Finally, controlled variables (or "controls") are the variables that never change, such as the combination of ingredients used (you would change the amounts of the ingredients, but each batch of slime would use the same list of ingredients.).

In a well-designed and simple experiment, you would only have one independent variable. You might want to test the effect of water on the slime, so you try several different recipes using different amounts of water, but you don't vary the amount of glue or borax at all. Or perhaps you want to test the effect of borax on the slime, so you do several different recipes, each with a different amount of borax, while keeping the amount of glue and the amount of water constant.

You may have heard the term "control group" before. That's the trial where you do everything normally with no changes to the independent variable. It's like the status quo, the regular, normal state of things. Having a control group allows you to see the results of your change.

A trial is one run of an experiment. In some experiments, only one trial can be performed, but to get the best results, you often will do at least three trials with identical situations. For example, in the paper airplane lab below, you would get results if you flew each airplane one time. However, if you threw each airplane three times and took the average of the three results, you would have a much more reliable picture of the airplane's true behavior.

In the slime example, it doesn't make much sense to make each recipe three times. That would be a waste of your materials as, presumably, if you use the same recipe each time, the results will be the same.

The Scientific Method Lesson Plan: Developing Hypotheses

Submitted by: charlie conway.

This is a lesson plan designed to be incorporated into a elementary or middle school general science class. Using BrainPOP and its resources, students will be introduced (or further exposed) to the steps necessary to undertake scientific experimentation leading (perhaps) to a Science Fair project. The Scientific Method is a core structure in learning about scientific inquiry, and although there are many variations of this set of procedures, they all usually have similar components. This lesson should take 45-60 minutes, with opportunities for extending the lesson further.

Students will:

• Students will use BrainPOP features to build their understandings of the Scientific Method.
• Students will learn how to identify and write effective hypotheses.
• Students will use game play to write an appropriate hypothesis for an experiment.
• Students will identify and utilize the tools necessary to design a scientific investigation.
• Laptops/Computers
• Interactive White Board
• Pencil/Paper
• Class set of photocopies of the Scientific Method Flow Chart
• BrainPOP accounts (optional)

Vocabulary:

Preparation:.

These procedures may be modified according to the needs/resources of each teacher & class. For example, you may decide to do the quiz with pencil/paper, or do the quiz as a class.

Lesson Procedure:

• Ask the students how scientists answer questions and solve problems. Take a few minutes to explore students' prior knowledge with a short discussion.
• Tell the class that you're going to watch a BrainPOP movie about answering a scientific question about plant growth.
• Show the BrainPOP movie on the Scientific Method two times. The first time, students should just watch and listen. The second time they should take notes. Pause the movie at critical STOP points.
• Students should log on to their individual student accounts and take the Scientific Method Quiz to give the teacher some immediate feedback. (This can also be done as a pre-assessment, or at the very end of the lesson). NOTE: If you choose to, you can give a pencil/paper quiz also; students who work best with electronic media can be given accommodations). If you don't have access to individual student logins via MyBrainPOP (a school subscription), students can take the Review Quiz or paper quiz instead.
• Discuss the main points from the movie: a. Write the definition of the scientific method: the procedure scientists use to help explain why things happen. b. Make a list on the board of the steps mentioned as part of the scientific method: problem, fact finding, observation, inference, hypothesis, experiment, conclusions. c. Tell students that there are various versions of the scientific method that they may see, but they are all basically the same.
• Hand out the Scientific Method Flow Chart . Introduce the "If...then...because..." format for writing hypotheses. Give the students 10 minutes to complete the sheet with their group. They may use their notes from the movie to help them, and/or work collaboratively with other students.
• Discuss some of the student responses in class. Focus on the hypotheses, and explain that a good hypothesis is a testable explanation of the problem. For example, a good hypothesis to the third problem would be, "If I move farther away from the microwave oven, then the cell phone signal will improve because I am further away from the source of interference." Show how this is a TESTABLE hypothesis that can lead to a scientific experiment.
• Introduce the students to the Pavlov’s Dog game in GameUP. Allow time for the kids to explore the game without telling them why they are playing it.
• After 10-15 minutes, have the students take a break from playing, and have a short discussion about the game. Ask if anyone was able to complete the task successfully, and have them share how they got the "diploma." If time allows, show the students how to complete the task so that they all understand that the dog has been conditioned to respond to a stimulus (noise before food has been introduced).
• Have the students write a hypothesis that Pavlov may have written before he started his experiment. Students can either do this with pencil/paper, or the teacher may create a BrainPOP quiz and have students submit their hypothesis electronically. This may be used as a part of the assessment.
• Choose some sample responses from the students, highlighting the hypotheses that are TESTABLE, and not just guesses or predictions.

If this lesson is an introduction to allowing students to plan and carry out their own experiments, then all that follows is naturally an extension to the lesson.

Other, shorter extensions are easy to develop as well.

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!

Stay tuned with us to unleash the world of  5th-grade science project ideas with hypothesis  and nurture your curiosity in the process.

What Is A Good Hypothesis For A Science Project?

Table of Contents

A good hypothesis for a science project is like a smart guess. It helps scientists figure out what they think will happen in their experiment. To make a good hypothesis, you need to use words like  if  and  then.  For example,  If I water the plant every day, then it will grow taller.  This shows what you’re going to do and what you expect to see.

In addition, a strong hypothesis also needs to be testable. That means you can experiment to see if it’s true or not. It’s like a detective’s clue that leads you to find the answer. Scientists use good hypotheses to guide their experiments and learn new things about the world. So, making a good hypothesis is an important part of any science project.

Things To Remember While Selecting A 5th Grade Science Project Ideas With Hypothesis

Here are some things to remember while selecting a 5th grade science project ideas with hypothesis:

1. Personal Interest

Choose a 5th-grade science project that interests you. Picking a topic you’re curious about makes the project more enjoyable. Whether it’s plants, animals, or space, your passion can make learning fun.

2. Age-Appropriate

Make sure the project is right for your grade level. A 5th-grade project shouldn’t be too simple or too complex. It should match your skills and what you’ve learned in school.

3. Available Resources

Check if you have access to the materials you need. Some projects might need special tools or expensive stuff. It’s essential to choose something you can do with the materials you have.

4. Safety First

Keep safety in mind. Select a project that’s safe to do at home or in school. Make sure you won’t be using anything harmful or dangerous.

5. Clear Instructions

Look for a project with clear instructions. It’s easier when you know what to do step by step. Projects with easy-to-follow directions help you succeed and learn better.

Developing A Hypothesis For Your Science Project

Developing a hypothesis for your science project is a crucial step. It’s like making an educated guess about what you think will happen during your experiment. Here are seven key points to consider while creating a hypothesis:

• Identify the Variables: Determine the two things you’re testing in your experiment, the  if  and  then  parts. For example, if you’re testing plant growth, the variables could be  amount of sunlight  and  plant height. 
• Be Specific: Make sure your hypothesis is clear and precise. Avoid vague or broad statements. The more specific, the better.
• Predict the Outcome: Your hypothesis should state what you expect to happen. Will one variable cause a change in the other? State your prediction clearly.
• Use  If-Then  Statements : Craft your hypothesis using  if-then  statements to show the relationship between the variables. For instance,  If the amount of sunlight increases, then the plant height will also increase. 
• Keep It Testable: Ensure that your hypothesis is something you can test through an experiment. It should lead to concrete results that you can measure.
• Avoid Bias: Make sure your hypothesis doesn’t show your personal beliefs. It should be based on research and evidence, not what you want to happen.
• Revisit and Revise : As you conduct your experiment, be ready to adjust your hypothesis if the results don’t match your initial prediction. Science is all about learning and adapting.

Free Scientific Method Printable Worksheet for Kids

May 19, 2014 by Stacie 11 Comments

This summer, we will be doing quite a few science experiments.  During the school year, we were a little lax on our experimenting, but I know the girls really love them, so I’m trying to make it up to them!

I wanted a way to keep track of the experiments we did, so I decided to design a printable scientific method worksheet to record and document them.  There are slight variations on the wording and exactly how the “scientific method” works, so I’ll share our steps.

Scientific Method (Printable for Kids)

1)  Ask a Question:  If you already have an experiment in mind, begin by piquing interest with a question.  Otherwise, you can do some research on a particular subject and record a question you want to answer.

2)  Make a Hypothesis:  Merriam-Webster defines hypothesis as “an idea or theory that is not proven but that leads to further study or discussion”.  After you ask a question, have your child form a hypothesis to predict what they think will happen.

3)  Test the Hypothesis:   This is where you get to design the experiment and actually complete it.  You’ll want to record what supplies you use and the procedure (or steps) you follow in the experiment.

4)  Record the Results:   Write or draw a picture to show what happened in the experiment.

5)  Draw a Conclusion:   Figure out if your experiment supported your hypothesis.
