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.

See and hear how sound waves travel through different types of materials. Extend the experiment online and learn how you can "see" with sound waves using ultrasound.

In this activity, learners experiment with their voices and noisemakers to understand the connections between vibrations and the sounds created by those vibrations.

This hands-on activity shows you how to make a shaker -- a small instrument with a big sound! Fill it with beads or even pennies for a cool sound.

In this activity, learners imitate the way vocal cords work by building a model from a plastic cup, rubber band, and a straw.

What's a Pickle-Oh? Two pieces of pickle on a stick are connected to a Pico Cricket (micro controller). When you slide the pickles apart the note changes.

In this activity, learners build a musical drum using a cardboard tube, plastic wrap, and beads.

In this interactive game, learners will test their memory of animal and insect sounds. Flip over cards, listen to the sound, and try to find the ones that match.

In this activity, learners explore sound by constructing tube zithers, stringed instruments from Southeast Asia and the South Pacific.

In this activity, learners use sound to figure out, or infer, the position of objects. Learners create a maze inside a shoebox with blocks of wood.

In this activity, learners explore sound by constructing their very own instruments using PVC pipes, soda bottles, and a straw.

Learners design and create musical instruments from common objects; their challenge is to create an instrument that can make three different tones.

This is an online simulation of how sound changes due to environment. How does place--like a cave, a pier, or a forest--affect certain sounds?

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

In this simple and fun activity, learners discover the relationship between vibration and sound by making a squeaky toy instrument out of simple household materials.

Sound can travel through a variety of media.

In this activity, learners build a slide whistle using PVC pipe, bamboo skewer, and piece of foam. Construction of the instrument is relatively simple.

This activity (on page 2 of the PDF under SciGirls Activity: Music and Sound) is a full inquiry investigation into sound frequency.

Put a string around your head, and play it! Learn about vibration, sounds, and pitch.

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.
