Science Fair Project Idea

Scientific Method

How can we make space stations with artificial gravity a reality? In this science project, you will explore the physics of creating artificial gravity with circular motion. Read more

Can Water Float on Water?

Science Fair Project Idea

Scientific Method

Of course it can, you say: ice is water and ice floats! And you're right. But we're talking about water in the liquid phase (the title reads better without getting overly specific). So how about it? Can liquid water float on water? Check out this project to find out. Read more

Now You See It, Now You Don't: A Chromatic Adaptation Project

Science Fair Project Idea

Scientific Method

This project shows that our perceptions can change, even with the stimulus remains the same. A clear color difference in an image disappears after just 20 seconds of looking at another (special) image. Now you see it, now you don't! Read more

The Birthday Paradox

Science Fair Project Idea

Scientific Method

This project shows how mathematical probability sometimes contradicts our intuition. Despite the fact that there are 365 days in a year, if you survey a random group of just 23 people there is a 50:50 chance that two of them will have the same birthday. Don't believe it? Try this project and see for yourself. Read more

How Does Distance Affect Wireless Signal Strength?

Science Fair Project Idea

Scientific Method

Are you ever annoyed by a poor Wi-Fi signal? What about when you try to send a text message, and it just won't go through because of poor cell service? Have you ever wondered what factors affect the strength of your signal and the speed of the connection? If so, this project is for you! Read more

Model How Environment and Genetics Change the Chances of Getting Cancer

Science Fair Project Idea

Scientific Method

What is cancer? How does it develop? Doctors and scientists have asked these questions for hundreds of years to understand cancer and find treatments. In this science project, you can investigate these questions too by building a simple model and exploring how environmental and genetic changes affect the development of cancer. Read more

How Does the Intensity of Light Change with Distance?

Science Fair Project Idea

Scientific Method

How does the intensity of a light source change as you move away from it? This project describes a method to verify the inverse square law: how light, sound, electrical signals, and gravity each decrease with distance from their source. It does not matter if you are talking about a lightbulb or the sun; this law still applies! Read more

Build a Simple Steerable Robot

Science Fair Project Idea

Engineering Design Process

Beginner robotics projects like the Art Bot and Bristlebots are fun, but the robots wobble around randomly and cannot steer. If you are ready for a robotics project that is a little more advanced (that does not require any programming), try this one out! You will build your own steerable robot with a wired remote control. Read more

Shed Light on Electric Generators: Do More Coils Generate More Electricity?

Science Fair Project Idea

Scientific Method

The electricity in your home probably comes from a power plant, but did you know that you can actually generate your own electricity? Wondering what it would take to light up a small light? This is your chance! In this electronics science project, you will build your own electric generator and investigate how to light up not just one, but two lights. Read more

Use a Catapult to Storm Castle Walls

Science Fair Project Idea

Scientific Method

You may have seen movies or read books where armies in medieval times catapulted large rocks or other objects at castles (or each other!). These armies used different types of catapults to accomplish different goals — for example, launching things over or into castle walls to knock them down. In this experiment, you will use a ping-pong ball catapult to lay siege to a "castle" and find the right settings to hit your targets. Read more
