30 Ideas For 7th Grade Science Fair Projects

By Beth Roberts | Last Updated May 4, 2022

We’ve compiled some of the best seventh grade science fair projects for your convenience! These science fair project ideas for 7th graders are sure to get you inspired and ready to do go on your own amazing research. We’ve also provided a list of resources you can use at home or in the classroom that will help give you tips on how to start your project, how to present it, and how to write an awesome science fair paper.

1. Drive A Balloon-Powered Car

This is an easy to build science fair project that you can even do with your younger brothers and sisters. You will need a high-quality balloon, scissors, tape, paperclip and a ruler.

First you will want to cut off the end of the balloon just above where half of it already has a hole in it. Then thread the tape through the hole so that it is on one side and stick the paperclip through it (close to the bottom of the balloon). Now take your ruler and measure how long it is going to be. When measuring however, you have to make sure that you are going to cut past where half of your paperclip is.

2. Make A Bionic Hand

This project involves making a bionic hand out of rubber and plastic parts and will involve cutting, gluing and soldering. You will want to be careful when cutting this project as you can seriously injure yourself if you cut too close to the plastic so make a good outline before doing it. First you will want to find out how big your hand is going to be. Then draw that on the rubber sheet with a pencil (minus the thumb where it will be). Measure how long your hand is going to be from top to bottom then measure 1/4″ from all 4 sides (you want 4 measurements).

3. Do An Experiment On The Physical Properties Of Water

This seventh grade science fair project assumes you already know some things about the physical properties of water. You will want to do this experiment with a partner who also knows some things about water. First you will want to find out whether or not your partner is willing to do this experiment with you and then measure out how many 1/2 cups of water there are in a gallon. Then take a sample of that and measure it again, this time in 1/4 cups. Then you will want to find out how many 4 oz cups are in your sample, then 1 cup and then 2 cups. Now take your results and do what is called an average of those measurements in a data table like this.

4. Make A Tornado In A Bottle

This project is somewhat easy but it may take some time to get right . You will want to do this by yourself as you can be seriously injured if you do the wrong thing. First you will want to take your empty soda bottle and rinse out all of the soda from it. Then make sure there is no water left in the bottle from rinsing it then soak it in water for about 20 minutes. After your 20 minutes are up, shake the water out of the bottle, but make sure you leave enough that it will not leak out as soon as you put in your dry ice (if you use dry ice).

5. Sorting Jellybeans is a Fun way To Learn about Heredity.

Use the following pointers to sort jellybeans :

a. Jellybeans come in blue, yellow, orange and pink jellybean colors (you can use colored paper and a different color of pen)

b. Jellybeans are round (you can use a ruler)

c. The outside edge of each jellybean is the “seam” that runs down the middle of the jellybean (you will be able to see this clearly after you fill the bag) 

6. Allow A Teabag To Float In The Air

This experiment is best done outside. First you will want to take a tea bag and put it in a glass of water , then carefully place it on top of the water in the cup. Make sure there is plenty of room between the cup and the tea bag (this will allow for air to circulate and help it to float). Watch as your teabag floats in mid-air!

7. Make A Slime Bomb

This science fair project is best done with an adult or older kid . You will want to find out what chemicals to use for the slime (you can search the internet for that) and then make it. It is best if you have a friend who knows how to make slime with you, too!

8. Build A Mini Catapult And Launch Yourself Across The Room

This science fair project can be fun , but it does take some time to get right. You will need several objects to build a mini catapult out of: a small stick, tape, string, paperclips and cans (for launching).

9. Make A Vacuum Cleaner Powered Fan

This science fair project is fun , but it can be dangerous. You will want to do this in an area where you do not have many dangerous electrical cords nearby and make sure you can easily get out of the way if it starts to fly off the ground. You will need a fan, a handheld vacuum, scissors and paperclips. First you will want to take apart your handheld vacuum and find the blade part of it. You will want to cut out about 1/2″ of the rubber around the blade. Then tape that on one side of your fan (make sure you have 2 blades facing each other).

10. Make A Solar Oven Design.

Students explore thermal energy, reflection, convection, and other physics principles as they experiment with the best way to create a solar oven . They’ll be able to serve up their experiment findings as well as their final reports!

11. Make A Rocket Powered By Dry Ice.

This is a science fair project that is best accompanied with someone who has done this before. You will want to make sure you are in an open area where you can easily get out of the way if it does not work.

First you will want to use a craft knife to cut out the bottom part of a soda bottle, making sure that you leave about 1/4″ on the bottom so it does not leak. About halfway up you will want to then cut off another part (this will be used for your air intake) and make sure your intake side is smaller than your exhaust side. Cut as close as possible so that they are seamless together.

12. Make Your Own Lava Lamp

This is a fun science fair project that involves melting wax and oil together . You will want to make sure you have something to put this in (a bottle, jar or plastic cup would work). You will need: red food coloring, water, dish detergent, oil (olive or vegetable), and that small globe from a lava lamp you might have lying around the house.

13. Take A Look At How The Greenhouse Effect Works.

The greenhouse effect is a natural phenomenon that can be observed in the Earth’s atmosphere on a daily basis. Many people are unaware of how it works and how much it affects our lives. This project encourages students to gain a better understanding of the greenhouse effect and its impact on Earth’s temperature.

14. Use Water Color To Make Your Own Kaleidoscope

You can use a permanent marker, paint or crayon. By varying the size and shape of the dots, you can create many different patterns in your result. Study how light is reflected in two and three dimensions of the pattern.

15. A Dense Rainbow Is Awe-Inspiring.

Density is the same as mass divided by volume . It is a measure of how tightly packed together molecules of matter are. This project forces students to learn about density in order to obtain a rainbow of monochromatic liquids in graduated cylinders that vary in size. The light source and liquid arrangement allows them to observe the density spectrum of each liquid.

16. Use Charcoal To Purify Water.

Water is one of the most important substances on Earth . It keeps us alive, purifies us and is also used to grow crops. Many people do not have access to clean drinking water and this project will help them by guiding them in the creation and use of charcoal for use in a filter for water purification.

17. Find Out How Energy Is Transformed.

Energy can be transformed from one form to another , but often loses some of its original properties. This project highlights the effects on a car battery if it is connected to a series of light bulbs and a conducting wire.

18. Make Your Own Tesla Coil.

Invented by Nikola Tesla in 1891, the Tesla Coil is an electrical resonant transformer circuit capable of producing extremely high voltages using an air-core transformer based on two spark gaps and two capacitors that allow alternating current through the primary coil to build up an oscillating high voltage in the secondary coil without requiring any type of power source with wires directly attached to it like you would find in conventional coils.

19. Coat Some Coins With Copper.

Copper-plating gives a metallic luster and color to many things , such as coins, jewelry, and even small kitchen utensils. In this project, students will use copper sulphate solution to convert a penny into a shiny plated coin.

20. Play With Hydraulics To See What You Can Come Up With.

Hydraulics is the study of fluids at rest or in motion and the mechanical devices that are directed by them. This project will allow students to learn about how pressure and force can be used to create movement and power.

21. Biofilms Should Be Collected And Managed.

Biofilms are naturally occurring communities of microorganisms , usually bacteria but also fungi and algae cells. Biofilms are found in almost all natural environments and on most man-made surfaces. They consist of living microbes that can persist for long periods, while producing tranquil points which may be as much as 100 times greater than their own area. This project introduces students to biofilms in order to encourage them to observe how they grow and how they are treated during the experiments.

22. Using Experiment Kits On Baking Soda And Vinegar, Make A Volcano.

An erupting volcano is an impressive sight to many people , but they are also extremely dangerous! In this experiment, students will learn about what causes volcanoes to erupt and what type of rocks are needed to build them with their own hands.

23. Crystals Are Fun To Grow And Play With.

Crystals are beautiful, fascinating and useful . Students will learn about how crystals grow by experiencing it themselves and observing the different ways they can form, with the help of a variety of experiment kits. This is a hands-on science experiment that encourages students to be creative, experience sensory impact and develop an intuitive understanding of materials as they work with them in real time.

24. Explore The Laws Of Motion Using A Spinner.

Gyroscopes are used in many aspects of our everyday lives . You know them as small spinning wheels that come with every electronic device nowadays, but their uses extend from guiding missiles and rockets in flight, to balancing boats and planes, to keeping your computer monitor from falling over on its side.

25. Make A Simple Breadboard To Use A Battery And Then Attach LEDs.

A breadboard is a board which allows you to connect multiple electronic components on one side . This project uses simple components to demonstrate the use of electricity in real time. You will need some type of battery and some LEDs, but you can buy these items at a local hardware store in addition to assembling the parts yourself.

26. Make A Simple Musical Instrument Using Simple Items.

A musical instrument is any object that is used to make music . In this project, students will use an empty plastic water bottle and some chopsticks to make a simple musical instrument; they will explore the laws of vibration by experimenting with a variety of sounds.

27. Make A Paper Airplane Which Can Fly.

A paper airplane is an aircraft designed to fly by being thrown . There are many variations of paper airplanes, but they all rely on the same basic structure and usually only require a piece of paper or thin cardboard. In this project, students will learn about aerodynamics as they build their own paper airplane.

28. Build A Storage Bin Using Recycled Materials

Storage bins are used to store clothing or other things that you do not need to use regularly but still want to keep around. This project will help students learn about the different shapes of storage bins and the ability they have to store things while being used in real time.

29. Make A Simple Compass.

A compass is a tool used to measure direction and orientation . It is used for navigation and orienteering. This project will help students explore the earth’s magnetic field using simple materials to create their own homemade compass.

30. Make A Rock Tumbler And Use It To Polish Rocks.

Polishing can be a valuable skill that provides aesthetic value and shiny, smooth surfaces for your household items. In this experiment, students will explore various sources for polishing rocks, as well as using their own creativity to create dazzling results in real-time during the experiment itself.

The field of science is vast and varied, with many different types of projects that students can engage in to learn about the world around them. Science projects can be engaging for students and teachers alike if they are designed to provoke a level of interest and excitement about what students are learning. It is also important to consider that science is not only limited to the four corners of a book or classroom; it is all around us, literally everywhere!

This means that there may be opportunities for children to learn while they are waiting in line at the bank, watching television at home, or even while they are otherwise being entertained.

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.

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.

With thousands of possible projects, it can be difficult to narrow down something that’s a good fit for every student. Try these tips to help them find the right science fair project ideas.

Match Your Project to Your Interests

This seems obvious, but it’s really helpful for kids who feel overwhelmed by all the choices. It’s also a good way to get reluctant learners more excited about science fair projects. Encourage students to think about what they love to do in their spare time. How can they turn that into a project?

For instance, kids who love sports might explore the most effective stretches for warming up, or methods for throwing a football farther and more accurately. Music lovers can learn how sound waves work, or discover the link between music and emotions. It’s all about starting with something you love.

Challenge Yourself, But Keep It Realistic

Science fair projects need to be something kids can complete by themselves or with adults in support roles only. If a student picks something that’s way beyond their skill level, chances are the parents will wind up doing most of it. That being said, the point of the project is to learn and grow. Aim to learn something new, whether it’s knowledge or skills, by setting measurable goals.

If You Want To Win, Be Innovative

For science fair contests with prizes, the more creative you can be, the better. Projects that address real-world problems with new and interesting solutions often catch the judges’ eye. Be sure to be thorough in your research, and be ready to answer questions about your methods and results. Scientists love asking questions!
