Little scientists will make inferences about hearing loss, pitch, and frequency in this great science fair idea that puts the human ear to the test.

Science fair project which examines the relationship between frequency of spider web vibration and spider's response time.

This science fair project idea determines if the temperature of rubber effects how high it bounces.

This is a fantastic and easy science experiment where kids will learn about elasticity by testing how high bouncy balls of different materials can bounce.

In this project, you'll build a model of the earth, complete with all seven continents and four major oceans.

In this science fair project, young children will become aware of and have the opportunity to experience the four basic tastes: sweet, sour, salty, and bitter.

This science fair project idea produces varying pitches of sound.

In this project, waves of vibrations are experimented with using water in glasses.

Discover whether different amounts of water added into a wine glass will produce a different pitch when their fingers are rubbed along the rim.

The purpose of this science fair project is to build a basic radio.

Science fair project which measures whether tsunamis are more destructive when they are caused by an earthquake or by a meteor.

Marshmallows are made of sugar, water, and air pockets. Since the marshmallow is flexible, will air pressure cause it to expand when heated in a microwave?

Science fair project examining barometric pressure, and how it can be used to predict the weather. How does atmospheric pressures relate to weather conditions?

In this pinto bean germination experiment, you'll learn about how fertilizer aids in growing pinto beans into seedlings.

The project investigates how friction affects motion by using different surface textures.

What is elasticity? Students will investigate how this concept applies to bouncing ball physics by testing the bounces of balls made out of different materials.

Science fair project that teaches you about chemical indicators and how to make your own in order to identify various mystery solutions.

These science fair experiments demonstrate the chemistry of rust and the oxidation process.

Examine which metal conducts more heat by boiling water in 3 pans made of aluminum, copper, and stainless steel.

This science research project challenges students to think of more effective lobster farming methods.

Will potatoes spud or sprout faster in dry, dark, or cold conditions? Find out in this science fair project idea!

In this project, several food items are tested to determine whether they contain starch.
