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.

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

Make stunning pendulum waves and learn the math behind the patterns generated with this cool and easy science project.

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

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

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.

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

Demonstrate how we are able to locate sounds, echolocation. Have a blindfolded subject locate you by the sound of your clapping.

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

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.
