Build a musical ice theremin by programming a micro controller, like a Pico Cricket to respond to resistance generated by the ice melting, or the ice being touched.

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

Sound can travel through a variety of media.

In this activity, learners explore electricity and conductivity to find that many things conduct electricity including copper, pencil lead, fruit, play-doh, and even people!

This is an activity about music, movement, and math. Learners will start a rhythm pattern with 2, 3, or 4 beats. For instance, tap your foot, jump, clap, repeat.

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.

With a bit of PVC, a laser, a can/cup, and a small mirror, you can make a device that visualizes you voice or any sound transmitted into the cup/can.

In this activity, learners investigate sound and vibration by making a "bee hummer"--a toy that sounds like a swarm of buzzing bees when you spin it around.

In this interactive game, learners compare their music-listening skills with that of a three-month-old baby.

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.

This is a web page that helps informal educators brainstorm on how to use a Pico Cricket (tiny computer) in an informal activity.

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

With a straw, two craft sticks, and some rubber bands, construct a noisemaker called a Sound Sandwich and explore how vibration produces sound.

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.

In this activity, you'll use a straw, a water bottle and a paper tube to make an instrument that's very much like a saxophone.

In this activity, learners construct wands that play different notes depending on information from light sensors programmed via a PICO Cricket.

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 (page 2 of the PDF under SciGirls Activity: Double Dutch) is a full inquiry investigation into whether hearing or seeing has a bigger effect on jump rope performance.

In this activity/demo about piezoelectricity, learners discover how some crystals produce electricity when squeezed.

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.
