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.

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?

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

Explore how sound waves are reflected and absorbed by producing echoes. Analyze which locations produce echoes.

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.

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

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.

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

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

Science fair project idea examines validity of mood ring predictions. Analyze accuracy of results, consider the impact of temperature
