Sorting Out Sedimentation

Science Fair Project Idea

Scientific Method

Sedimentary rock forms in layers that are deposited one after the other over long periods of time. Oftentimes, sedimentary rock contains fossils and other debris that are deposited within the layers. How do sediments form? How are sediments of different shapes, sizes, and types sorted during the process of sedimentation? Find out in this science fair project! Read more

Moss is Boss: Using Plants to Determine Direction

Science Fair Project Idea

Scientific Method

Have you ever gone camping, looked up at the stars, and found the Big Dipper? Two stars in the dipper part of this constellation point to Polaris, the north star, which people have used for thousands of years to help them find their way. In this plant biology science fair project, you'll investigate whether plants, like moss, can help you find your way, too. Read more

What's the Best Method to Communicate Data Graphically?: An Experiment in Visual Perception

Science Fair Project Idea

Scientific Method

Graphical methods of data presentation are a key feature of scientific communication. This project will get you thinking about how to find the best way to communicate scientific information. Read more

Testing the Strength of Martian Bricks

Science Fair Project Idea

Scientific Method

For a colony of humans to survive and thrive on Mars, they will need to make the most of what is available on Mars. We know from prior space missions what the Martian ground cover looks like. In this project, you will see if this ground cover can be transformed into strong construction material. The first requirement for construction material is that it is strong so it does not collapse under its own weight. Because the mass of Mars is about 10 times less than the mass of Earth, its… Read more

Spare a Watt, Save a Lot

Science Fair Project Idea

Scientific Method

Do you know how much power is used every day in your home? What you might not realize is that making simple changes can save you energy, power, and money. What would you do with extra money? Put it in the bank or get something that you really want? In this science fair project, you will investigate the different uses of electricity in your home and determine if there are simple changes that you can make to save energy and money. Read more

Build an Adaptive Game Controller for a Raspberry Pi

Science Fair Project Idea

Engineering Design Process

People with limited mobility, especially in their hands, may not be able to use traditional video game controllers. Adaptive game controllers use a variety of peripherals, like larger buttons, foot pedals, or specialized joysticks, to let people with limited mobility play video games. This video shows how to build a very simple adaptive controller that works with Scratch games on a Raspberry Pi. Can you build an adaptive game controller for a hardware platform and game of your choice? If you… Read more

Invent an Interactive Toy with a Raspberry Pi

Science Fair Project Idea

Scientific Method

Did you ever have a favorite toy like an action figure or doll that could light up, make noise, or move? This project will show you how to make your own interactive toy using a Raspberry Pi. Check out the video to see what this simple, but fun, project looks like. The version you make does not have to be a robot; it can be any shape and have any sound effects you want. IMPORTANT: The instructions for this project were originally written using Scratch 2 on a Raspberry Pi 3B+. If you are using a… Read more

Only If They Think They Can Get Away with It?

Science Fair Project Idea

Scientific Method

How many times have you seen a car without the appropriate permit (either a license plate or placard that hangs from the rearview mirror) parked in an accessible parking space reserved for people with disabilities? If you find this behavior upsetting, you might be interested in figuring out how to discourage "cheaters" who use these spaces to make a quick trip into the store. Is it enough to let them know someone might be watching? Read more

Burning Biofuels: Comparing Nonrenewable and Renewable Fuels

Science Fair Project Idea

Scientific Method

Have you considered where the gasoline that your parents put in your car comes from and how long that source will last? The fuel that most vehicles use, gasoline, is a petroleum product. Petroleum is a fossil fuel and is a nonrenewable form of energy, meaning we use it faster than it is able to be reproduced. Burning fossil fuels also produces pollutants that might hurt our environment. Using a kind of fuel from a renewable source would help save Earth's natural resources and cut down on… Read more

The Effect of Roasting on Color, Flavor, and Texture of Peanut Butter

Science Fair Project Idea

Scientific Method

Peanut butter is a popular ingredient in sandwiches, cookies, and many other common foods. In this cooking and food science fair project, you will roast peanuts in the oven at 350 degrees for 20, 30, and 40 minutes to produce variable levels of color and flavor. Roasting not only adds complex flavors to the peanuts, but it also destroys enzymes that produce off-flavors. Each lot of roasted peanuts will be used to make a batch of peanut butter. You will evaluate each batch of peanut butter for… Read more
