Learn about the layers of the Earth and make a model! Create a earth layer book, cake, or clay diagram.

This science fair project idea produces sounds by creating vibrations using different objects.

How does a kazoo, the strings of a guitar, or the speaker of a radio make sound? The purpose of this science fair project is to show how vibration makes sound.

Science fair project that examines what causes thunder and why a thunderclap sounds so loud. How is lightening related to the creation of sound waves?

Learn about sound physics and do a survey experiment to explore the difference between sound and noise in this science project.

This science fair project idea produces varying pitches of sound.

Take a closer look at your furry friend (or the furry friend of a neighbor -- with permission) to discover if communication exists between cats and humans.

This science fair project idea demonstrates that light travels in straight lines and experiments with reflecting light.

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.

How does the size of a vibrating surface affect the pitch of a drum? Learn about drum size and pitch with this easy science fair project idea.

Can a horse lead itself to the carrot? Train your horse with carrots and boxes and test horse memory in this fun zoology science fair project.

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

This activity challenges students to use computational thinking as they create a sequence of commands that will make a robot move in a pattern related to the sound and rhythm of music.

In this activity, students will think about the form and function of household objects as they compare and contrast kitchen serving spoons of various sizes and designs.

Science fair project that examines how temperature affects density and how density in turn affects the behavior of helium gas.

In this Bernoulli's Principle experiment, you'll learn how an increase in the speed of a fluid, like air, decreases pressure.

How good are humans at sound localization? Kids can try this cool science fair project idea to see how good their friends are at judging sound direction.

In this open-ended activity, students will be given a small quantity of three types of materials and asked to design a prototype for “something that will improve the school.”

This activity challenges students to use computational thinking as they create a sequence of commands that will make a robot navigate around several obstacles.

In this activity, your student will be invited to build a chair out of building blocks that is designed to meet the specific size and shape of a small doll or toy figure.

This science fair project demonstrates the magic of arches by challenging students to stack telephone books on top of eggs without breaking them.

In this activity, students will create a stop motion animation by creating a clay figure and taking a series of digital photographs.

What is a wedge? Kids find out by experimenting with different wedges in this simple science fair project idea.

This activity challenges your student to use spatial reasoning and computational thinking to program multiple robots.
