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.

Listen to the beat of gravity. By taking two strings with weights tied to them at different, yet uniform intervals, you can hear the uniformity (and rhythm) of gravity's accelerating pull.

In this activity, leaners build their very own rainsticks, an instrument filled with pebbles and seeds that create sounds like falling rain. Save costs by using material found around the home.

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

In this activity, you'll use a paper cup, a piece of cloth, and some string to make a musical instrument called a cuica (pronounced KWEE-kah).

In this quick and easy activity, learners build an air cannon "drum" and see what happens when they "shoot" puffs of air at different targets.

In this activity, learners explore sound by constructing their very own banjo out of a coffee can. Learners experiment with the canjo to change the instrument's pitch and timbre.

What happens when two wave pulses meet in the middle? Send waves down a spring to watch them travel and interact.

In this activity related to music and sound vibrations, learners make a phonograph or record player out of simple materials. First, learners assemble the turntable, arm, and sound cone.

Do you have an extra portable cassette tape player hanging around?

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

Make your own simple speaker so you can listen to your favorite radio station. Just wind a coil, attach it to a piece of cardboard or Styrofoam, hold a magnet nearby, and listen.

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.

In this activity (4th on the page), learners conduct a series of tests to find out which of their ears is more dominant.
