Determine the relationship between the speed of a sound and the temperature of the air it passes through.

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

Find a mathematical relationship between the intensity of a sound wave and distance from the sound source. Use a pedometer and a sound level meter.

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

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?

This awesome diffraction grating experiment puts high school students' applied math skills to the test by having them calculate the wavelength of laser light.

Check out this fun science fair project idea to learn about seismic waves and how fast they travel during an earthquake.

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

In this cool sound resonance experiment, learn about frequency and pitch, and use a tuning fork to calculate sound velocity in air.

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

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

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.

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 cool science fair project, kids apply basic algebra to learn how to make a PVC pipe instrument while exploring concepts like frequency and resonance.

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.

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

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

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