Excess Volume: Investigate the "Shrinking Liquids" Effect

Science Fair Project Idea

Scientific Method

Cooking, washing, and many industrial processes involve the mixing of liquids. How liquids behave when they are mixed is dependent on many factors. Sometimes, the mixing behavior of liquids can be quite surprising! For example, when you mix 50 mL of one liquid with 50 mL of another liquid, you might not end up with a 100 mL mixture! In this science project, you will explore this phenomenon, which we call the "excess volume" of mixtures. How do you think your mixing volumes will… Read more

Electric Paint: Light Up Your Painting

Science Fair Project Idea

Scientific Method

Electric paint is a fun way to include a circuit with lights in an art project, but it presents a challenge not found in traditional electronic circuits. What happens if you change the length or width of your strokes of paint, such as by painting longer, curvier lines or using a thicker brush? Could this affect the electrical properties of your circuit? Try this project to find out! Read more

Magnetic Levitation: Experiments with 'Anti-magnets'

Science Fair Project Idea

Scientific Method

What happens if you hold a magnet next to water? You might think that water is not affected by magnetism, but in fact, the water is slightly repelled. Believe it or not, if the magnet is strong enough, you can use this effect to levitate objects that contain water, including insects and even small frogs! In this science project, you will learn about diamagnetism. Materials that are repelled by both poles of a magnet are called diamagnetic. The magnets you will use are not strong enough to float… Read more

Devising an Algorithm for Solving Rubik's Cube

Science Fair Project Idea

Scientific Method

If you're the kind of person who has taken apart your Rubik's cube in order to grease the inside parts so it will move more smoothly, this could be a great project for you. We'll show you three sets of move sequences that accomplish specific rearrangements of the cube. Can you devise a way to solve the cube using only these three move sequences? Read more

Less Cowbell! The Unconstrained Truth About Constrained-Layer Damping

Science Fair Project Idea

Scientific Method

Noise is everywhere. From the clanking of a cowbell to the din of the lunchroom, we are surrounded by noise. Sometimes there's no way to get away from it, but there is a way to deal with it—constrained-layer damping. By simply creating a layered sandwich of somewhat flexible materials, what was once a noisy cowbell can become a "noise blanket." This science fair project shows you how to transform a noisy piece of metal into a sound-muffling constrained-layer damper. You'll record the… Read more

Materials for Sound Barriers

Science Fair Project Idea

Scientific Method

What are the best materials to use for blocking out unwanted noise from the environment? You can build a test box (or test frame) around an audio speaker. Use a sound level meter to measure the speaker output. Use different materials to cover the walls of your test box (or frame), and see which materials do the best job at blocking the sound. For a more advanced project, perform your tests using different sound frequencies. Are some materials better at blocking certain frequencies than… Read more

Motorizing a Robotic Hand

Science Fair Project Idea

Scientific Method

Imagine how cool it would be to have your own motorized robot hand. Well, stop imagining and turn that daydream into reality! Start out by designing and building a robot hand. The Science Buddies project Grasping With Straws: Make a Robot Hand Using Drinking Straws shows you a simple way to make a robot hand with drinking straws, or you can design a robot hand from any other materials you think are suitable. Your hand design will need sewing threads, or some other mechanism, for motors to… Read more

Aerodynamics and Bridge Design

Science Fair Project Idea

Scientific Method

Research the famous collapse of the Tacoma Narrows suspension bridge. What lessons were learned about the potentially damaging effects of wind on bridges? What structures stabilize a bridge against wind forces? Build models and use a wind tunnel to test your hypothesis. Read more

Bet You Can't Hit Me! The Science of Catapult Statistics

Science Fair Project Idea

Scientific Method

If you have ever tried to hit a target (such as a trash can) with a wad of paper, you know that aim is everything. But it is not always easy to get it right every time! Missing is not that big a deal with a wad of paper, but what if you were in an invading army in the Middle Ages, using a catapult to hurl huge stones and knock down castle walls? For a successful invasion, it would be important to know exactly how far, and how reliably, a catapult could launch a projectile. In this project you… Read more

Build an Obstacle-Avoiding Robot (BlueBot Project #4)

Science Fair Project Idea

Scientific Method

In the animal kingdom, many different critters use whiskers to help them find their way around in the dark, through murky waters, or even to help them hunt prey. Whiskers can be very useful when the animals cannot rely on sight. Did you know that you can also build a robot that uses "whiskers" to find its way around? This project will show you how to build a simple robot that uses whiskers as "bump sensors" to help the robot detect when it is about to bump into an obstacle, so it can turn… Read more
