Have Your Chips Lost Their Chomp? Understanding How Food Becomes Rancid

Science Fair Project Idea

Scientific Method

You are looking under your bed for that video game you want to play, when you come across a real treasure—an open bag of potato chips that you forgot about! A crispy and salty potato chip is a tasty treat. But wait! This potato chip is not crisp and does not taste as great as it should. What happened? The chips have gone rancid! In this cooking and food science fair project, you will look into what factors turned your chips rancid. Read more

Seeing Beyond the Visible: Photography with Near Infrared Illumination

Science Fair Project Idea

Scientific Method

Have you ever wondered what it would be like to have an extra sense? What if you could hear above the normal range (ultrasound) like dogs or bats? What if you could see ultraviolet light, like bees or juvenile trout? What if you could see infrared light, like a rattlesnake or boa constrictor? This project shows you how you can use a phone or camera, tripod, and a special filter to take pictures using near infrared illumination. It's a whole new way of looking at the world. Read more

Breath of Life: Does Exercise Increase Vital Capacity?

Science Fair Project Idea

Scientific Method

How much air do you think you breathe in when you take a deep breath? Can you increase your lung capacity by exercising regularly? Do athletes have greater lung capacity than non-athletes? This project shows you how you can find out. Read more

Measuring the Speed of Moving Objects with Stroboscopic Photography

Science Fair Project Idea

Scientific Method

A strobe light can illuminate an entire room in just tens of microseconds. Inexpensive strobe lights can flash up to 10 or 20 times per second. This project shows you how to use stroboscopic photography to analyze motion. Read more

Wild Winds: Detecting Turbulence Around Structures

Science Fair Project Idea

Scientific Method

Watch out! Eddies and vortexes are powerful regions of air and water flow that you have to watch out for in some surprising places. Try out this science fair project to discover why they can be dangerous, as well as where and how to find them. Read more

Divide and Conquer: Proving Pick's Theorem for Lattice Polygons

Science Fair Project Idea

Scientific Method

If you like to play Tetris, then you might like this project. You will learn something interesting about the mathematics of complex shapes as you try to prove Pick's Theorem. The strange shape below is an example of a lattice polygon, which is a polygon whose vertices lie on points in the plane that have integer coordinates. As you can see, it is a complex shape, but there is an easy way to calculate its area, by simply counting lattice points! If you count the number of lattice points on… Read more

Earthworm Castings — The Ideal Proportion in Soil for Young Garden Plants

Science Fair Project Idea

Scientific Method

Everybody knows that worms are good for the soil, but not everybody knows why. Here's a project that investigates just one of the ways earthworms improve the earth. Would earthworm castings (or earthworm manure) help your plants prosper and flourish? If so, how much should you use? Read more

Build a Light-Up Activity Timer

Science Fair Project Idea

Engineering Design Process

Do you have trouble remembering when to stop playing and clean up? Have you ever had little kids throw a tantrum about cleaning up while you were babysitting? If so, this project is for you! You will convert a stuffed animal into a light-up activity timer. You can use the timer for different activities like play, exercise, or doing homework. What you use it for is up to you! Read more

Around the World: The Geometry of Shooting Baskets

Science Fair Project Idea

Scientific Method

Take shots at a set distance from the basket, but systematically vary the angle to the backboard. For a basic project: How do you think your success rate will vary with angle? Draw a conclusion from your experimental results. A bar graph showing success rate at different angles can help to illustrate your conclusion. For a more advanced project: Use your knowledge of geometry and basketball to come up with a mathematical expression to predict your success rate as a function of angle… Read more

Fear Factor: Using Pulse Rate to Measure Emotion

Science Fair Project Idea

Scientific Method

Oh, were you ever scared! Your heart pounded, your breath rate shot up, your palms got cold and clammy. Fear does that to us. Here's a science project based on roller coaster rides to see if heart rate is an accurate measurement of fear. Are you brave enough to take on this frightfully fun project? Read more
