In this physics project, learn about the relationship between light intensity and distance using a laser pointer, flashlight, and graph paper!

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

This science fair project examines how tsunamis travel by simulating a tsunami moving around an island. You will generate a pretend tsunami in a swimming pool.

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.

Using an empty tennis ball can and a swimming pool, you will determine if it's possible to have a conversation under water.

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.

This science fair project demonstrates the principles of reflection through simple experiments involving mirrors and light.

Observe how your brain works while it is focused on one thing, and how it works while you are distracted by another thing.

This science fair project idea produces varying pitches of sound.

The objective of this science fair project idea is to determine if sound travels best through the air, water or a solid.
