In this game, learners create flash cards with an image on one side (of an animal, for example) and the sound that animal makes on the other.

In this activity (7th activity on the page), learners use their sense of hearing to find a "sound match." Learners shake containers filled with items like dry seeds, sand, beans, etc.

In this activity, learners discover how bats use echolocation to get information about objects in their environment. During the activity, one learner whispers into a tube.

In this activity, learners create a traditional Mexican noisemaker (a matraca) using cardboard, craft sticks, and a wooden dowel.

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

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.

Make your own speaker with a magnet, wire, and paper cup! If you have a radio with a headphone plug and an old pair of headphones, this is a great tinkering activity.

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.

In this activity, learners explore sound by constructing an instrument toy that buzzes when you swing it.

This activity provides step-by-step instructions on how to build a rain stick, a musical instrument originating in South America.

Use echolocation to find others and experience how whales’ senses have adapted to suit their environment. In pairs, learners are blindfolded and use containers filled with marbles to find each other.

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.

In this design challenge activity, learners build a four-stringed instrument that can play a tune.

Learners build a simple electromagnet, then use this electromagnet to transform a yogurt container into a working speaker. They can connect their speaker to a radio and listen as it transmits sound.

This activity was designed for blind learners, but all types of learners can model how vibrating particles, such as in a sound wave, bump into other particles causing them to vibrate, and that the vib

Focus sound through a balloon! In this Exploratorium activity, you'll use dry ice to create a balloon that's a sound lens.

From this How To slide show, you create an Audio Tape Bow that can play distorted audio sounds by running it across a tape head.

This lesson (on pages 15-24 of PDF) explores how sound is caused by vibrating objects. It explains that we hear by feeling vibrations passing through the air.

In this activity, learners observe, explore and investigate vibrating instruments in everyday places and create music in unique ways.

In this activity, learners explore how sound travels through solid objects better than through air. Leaners attach a metal clothes hanger to a piece of string and hold it to their ears.
