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

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.

This science fair project creates a visual model of whatâs happening to sound waves as a car approaches and then leaves.
