A Model of Gravity in Our Solar System

Science Fair Project Idea

Scientific Method

Why do the planets orbit the sun without flying off into space? Do they move in perfect circles or do their orbits take a different shape? And how could you possibly do a science project about any of this—you can't do an experiment with the planets! However, you can build a model of our solar system that demonstrates the concept of gravity, using balls of different sizes to represent the sun and planets. Watch the summary video for an excellent introduction to the model. Think about how… Read more

Absorption of Radiant Energy by Different Colors

Science Fair Project Idea

Scientific Method

Everyone has experienced the warmth provided by a shaft of sunlight through a window. In this physics science fair project, you will determine how the color of an object affects the amount of radiant energy that is absorbed. You will then use the Stefan-Boltzmann equation to determine the amount of energy that is absorbed and re-emitted by the different colors. Read more

AI Hyperrealism: Do AI Faces Look More Real Than Human Faces?

Science Fair Project Idea

Scientific Method

Artificial intelligence (AI) programs can now generate photorealistic pictures of people who do not exist in the real world. How can you tell if a picture is of a real person or a fake, AI-generated person? What features of the picture do people use to decide whether the face is real or AI-generated? In this project, you will explore these questions as you ask volunteers to look at both real and AI-generated pictures of human faces. Read more

Have you ever been tricked by an optical illusion? Optical illusions can be fun, but they are also quite scientific. In this activity you will investigate the phenomenon of apparent motion by making your own flipbook animations. Read more

Archimedes Squeeze: At What Diameter Does an Aluminum Boat Sink?

Science Fair Project Idea

Scientific Method

Where do you get your best ideas? At school with your friends? When you are out for a bike ride? Over 2,200 years ago, a scientist named Archimedes got one of his best ideas when he sat down in his bath. Eureka! He went running through the streets without even bothering with his clothes. What was he so excited about? He had discovered that when objects, like his body, are placed in water, water is pushed out of the way. Have you noticed that, too? The weight of the water that is pushed out of… Read more

Have you ever seen a mobile? Not a mobile phone, but a hanging art sculpture. You might have had such a mobile in your room when you were little. These mobiles hang from the ceiling and are usually made up of many layers of rods to which lots of differently shaped objects are attached with strings. When you look at the mobile sculpture, you might wonder how it can stay balanced all the time even when it is moving in the air. In this activity, you will make your own mobile sculpture and find out… Read more

Basketball Physics: Where Does a Bouncing Ball's Energy Go?

Science Fair Project Idea

Scientific Method

Have you ever noticed that when you drop a basketball, its bounce does not reach the height you dropped it from? Why is that? When a basketball bounces, such as on a basketball court, its bounce actually loses momentum by transferring energy elsewhere. This means that to dribble the basketball, players must continually replace the transferred energy by pushing down on the ball. But what happens to the "lost" energy? As we know from physics, energy is not really lost, it just changes form. One… Read more

Basketball: The Geometry of Banking a Basket

Science Fair Project Idea

Scientific Method

If you've ever played or watched basketball, you might already know that your chances of successfully banking a shot on the backboard are higher in certain positions on the basketball court, even when keeping the distance from the hoop the same. Ever wondered what would account for this? Do you think you could actually explain this using geometry? This science project will put your knowledge of geometry and algebra to good use. You will calculate and quantify how much more difficult it is to… Read more

Bombs Away! A Ping Pong Catapult

Science Fair Project Idea

Scientific Method

If you were in a raiding army in the Middle Ages, a catapult would come in mighty handy for taking down castle walls. But only if you could aim it reliably! With this science project, you will try your hand at catapult technology. Using a rubber-band-powered catapult you will send ping pong balls flying through the air. The catapult's design makes it easy to measure and repeat how hard the ball is launched and its direction, so you can find the right catapult settings to hit the target reliably. Read more
