We listen to stereo music systems, tv's, and radios because it simulates being where the sound originates.

In this activity, learners explore sound by constructing an instrument using some metal pipes, rubber bands, and a baseboard.

Create an instrument that you don't play--you just listen to it through tubes of various lengths.

In this activity, learners create a sound visualizer from common materials to help see the vibrations created by sound. Sounds from a tone generator make salt dance on a vibrating balloon membrane.

This game depicts a woman going through her day, faced with various loud sounds.

This game plays a dozen different sounds, altered to simulate what they would sound like if you had hearing loss.

In this activity, learners construct a playable kazoo from inexpensive materials. They will experience how vibration creates sound waves and music.

Discover how sound travels and what materials make better sound conductors. Can you hear better with your fingers in your ears? Find out with a coat hanger and some string!

In this activity, learners investigate sound wave science, in stereo! Learners construct a "stereo" out of a metal coat hanger and piece of string to explore sound vibrations.

This is a virtual representation of a sound mixer containing pre-looped sounds of animal, insect, and environmental noises.

In this activity, learners create a xylophone by filling glasses with different amounts of water and tapping them with a metal spoon.

In this activity, learners create a hearing based memory game that they can share with friends.

Audio Boggle is an activity that lets you listen to a track (that you make yourself) and see what you can hear!

In this group activity, learners see and hear the speed of sound. A learner designated the "gonger" hits a gong, once every second, as the rest of the group watches and listens from a distance.

In this activity (on pages 25-32 of PDF), learners make models of the inner ear out of pipe cleaners.

In this activity, learners investigate the sense of hearing and plan and conduct their own experiments.

In this game (4th activity on the page) about hearing, learners test their ability to identify various sounds without looking.

In this activity (described on pages 39-42 of PDF), learners make a paper wheel (on pages 57-60 of PDF) that shows them the relative loudness of different sounds.

Find out what it would be like to have ears shaped differently from your own! Design and make different animal ears then try them out.

In this activity, learners explore sound by constructing a simple piano out of wood and craft sticks.
