In this project students determine which instruments composers use to create birdsongs and birdcalls in classical music.

The objective of this experiment is to identify common materials that absorb sound waves with the greatest efficiency.

In this fun science fair project idea learn about the multiple sources of radio waves and fin out how difficult it is to block them.

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.

Find out whether matching resonant frequencies can cause objects to shatter.

The goal of this science fair project is to evaluate the effect of heat on sound wave frequency.

How fast does light travel in different mediums? Kids conduct a cool refraction experiment in materials like water and air for this science fair project.

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.

Look for a correlation between temperature and the intensity of cricket chirping. Measure ambient temperature and sound intensity in decibels.

This classic children's game demonstrates how sound travels through air vs. through a solid.

This science fair project idea produces varying pitches of sound.

In this science fair experiment, students learn about the scientific principles behind Doppler ultrasound.

This experiment will explore how mallets of various materials and weight create sonic tones of varying lengths.

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.

This science fair project idea shows how a vibrating object transfers energy to whatever it touches.

Design a hearing protection device to protect their ears from loud noises. Examine the properties of current protective hearing devices, materials.

This experiment investigates whether there are certain sounds that affect men and women differently
