Think it takes expensive, sophisticated equipment to measure the speed of light? Think again! Outfit yourself with a simple handheld laser pointer, a protractor, and gelatin, and you're ready to get started. Read more

Have you ever wondered why a water strider can walk on water? Or how detergent can clean your dishes? If you observe carefully, you can find dozens of similarly interesting phenomena that are all linked to the surface tension of water. In this science project, you will investigate the properties of water surface tension. Read more

Did you know that when you dip your finger in water and pull it out, the water is actually pulling back on you? Here's a way you can measure how much. Read more

This physics project seems like it should have an easy answer. Instead, it turns out to be a great illustration of why it is important to base scientific conclusions on the outcome of controlled experiments. Things don't always turn out as we expect! Read more

In physics class, you have probably rolled your eyes at some point after being assigned a "projectile motion" homework problem where you use equations to predict how a ball will move through the air. This experiment will show you just how fun that problem can be by using a real catapult to launch a ball and videotaping it as it flies along its path. Then, you will analyze the video and compare it to what the equations predicted. If you have ever wondered if those equations in your physics… Read more

Did you know that you can figure out how much sugar is in a liquid without ever tasting it? In this science fair project, you will learn how to measure the concentration of sugar dissolved in a liquid by using a laser pointer, a hollow prism, and some physics. You will discover how refraction, or the bending of light, is the key to measuring the sugar content of a liquid with a laser pointer. Read more

In this cricket-inspired engineering challenge, you will build a machine to launch a ball and knock down a target (called a wicket). How many times can you knock down the wicket in three minutes? Follow the contest rules to try it out and enter the 2020 Fluor Engineering Challenge! Available in Spanish (Español). Teachers, lesson plan versions of this challenge are also available. Read more

Did you know that you can lift an object that's heavier than you are? Just use a lever! In this science project you'll build a tabletop lever and measure how much effort it takes to lift an object using it. Read more

If you like listening to music and making crafts, this is a great project for you. You will learn how to make a completely functional speaker that you can use to listen to real music...out of paper! Along the way, you will learn about the science behind how a speaker works. Speakers depend on magnets to create sound—does adding more magnets make the sound louder? Try this project to find out! This project is compatible with Google's Science Journal app, which allows you to collect data… Read more

A kaleidoscope is a fun toy that creates amazing images when you look into it. Wouldn't it be fun to create those images yourself? Check out this project to learn how to build your own kaleidoscope and to learn how the inside of a kaleidoscope works. Then you can create and adjust your own amazing, colorful images! Read more
