Antlion Pits in Open Sand or Under Leaf Cover

Science Fair Project Idea

Scientific Method

Antlion larvae are known for their predatory ways. In sandy areas, they dig pits to trap ants or other crawling insects that happen to stumble in. This project shows you how to create a mini-environment for antlion larvae to test their preferences for pit-building sites. Read more

Explore Optical Illusions: Build an Infinity Mirror

Science Fair Project Idea

Scientific Method

Do you want to trick friends and visitors with an amazing optical illusion? In this engineering design project you will learn how to build an infinity mirror,with built-in lights that make the mirror look like a deep tunnel with no end. But pick the mirror up and look behind it, and you will see that it is only a couple of inches thick! Read this project to find out not only how this illusion works, but how to design and build your very own infinity mirror from scratch. Read more

Can Humans Recognize AI-Generated Images?

Science Fair Project Idea

Scientific Method

Can you tell if the pictures on this page are real or generated by a computer? Artificial intelligence (AI) generated images have exploded in popularity, bringing plenty of controversy along with them. An AI-generated image of a tiger or a flower might seem harmless, but artificial images of people or events can contribute to "fake news." In this science project you will investigate whether people can tell the difference between real pictures and pictures generated by AI. Can you spot the… Read more

Hydroponics: Gardening Without Soil

Science Fair Project Idea

Scientific Method

What do plants need to grow? Most of us would answer that they need light, air, water, and soil. But by using a process called hydroponics, you can grow plants without soil! How does it work? Try this project and see for yourself! Read more

Big Pieces or Small Pieces: Which React Faster?

Science Fair Project Idea

Scientific Method

Some chemical reactions occur explosively fast, others may occur almost imperceptibly s-l-o-w-l-y. This project explores what effect the particle size of the reactants has on the speed of a chemical reaction: production of carbon dioxide gas by an Alka-Seltzer® tablet. Read more

The Nose Knows Smell but How About Taste?

Science Fair Project Idea

Scientific Method

Ahchoo! Got that stuffy nose and I-can't-breathe kind of cold? Those sniffles and clogged sinuses are bad enough, but why does it also seem everything tastes so bland and flavorless when we are sick? Is there really truth to the idea that smell is a key part of taste? Gather up a few volunteers, hit the kitchen, and try this experiment to find out. Read more

How the Strength of a Magnet Varies with Temperature

Science Fair Project Idea

Scientific Method

Physicists sometimes study matter under extreme conditions. For example, think of the emptiness of interstellar space vs. the unimaginable crush of pressure at the center of a neutron star, or an object dipped in liquid nitrogen vs. the tiles on the space shuttle during re-entry. Here's an experiment on permanent magnets in "extreme kitchen" conditions that you can try at home. Read more

The Effect of Bridge Design on Weight Bearing Capacity

Science Fair Project Idea

Scientific Method

Build model bridges and then deliberately destroy them? Who'd be crazy enough to try that? Read more

Back and Forth to Go Forward: A Snake on Wheels?

Science Fair Project Idea

Scientific Method

Have you ever ridden on a Roller Racer® or PlasmaCar®? These are ride-on toys that you move ahead by moving the steering mechanism back and forth. You've probably seen skateboarders "slaloming" on level ground to keep rolling, it's basically the same idea. This project explores the physics behind this method of locomotion. Read more

Build a Solar-Powered Car

Science Fair Project Idea

Scientific Method

Do you want to build a solar-powered car? How about enter it in a competition and race it against other people's designs? If so, this is the project for you! These instructions will show you how to get started building a solar-powered car that you can enter in a science or engineering fair. No experience needed. If you want, you can even compete in the Junior Solar Sprint, a regional competition for solar-powered cars. Get more information about your regional competition. Are you a… Read more
