Put on a pair of gloves and be the conductor of your invisible orchestra!

In this activity, learners explore how musical instruments are engineered.

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

This is a simple activity for learners to create a traditional musical instrument. Pan Pipes have developed all over the world in different cultures, from South America to Greece and China.

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

Play-Doh is conductive! Use the semiconductive qualities of Play-Doh to make your own squeezable instrument. Pico Cricket is required.

In this activity, learners will create their own percussion instrument with recycled materials. Learners will explore design, fabrication, cause and effect and sound through this activity.

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.

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!

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.

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 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.

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.

This activity requires a Pico Cricket (tiny computer). Learners work on designing and building a sound sensor out of household materials, like plastic wrap and cardboard.

In this activity, learners listen to songs and decode hidden messages based on the same principle as a modem. As a final challenge, learners decode the binary messages in a music video.

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

Learners explore soybeans, soak them in water to remove their coat, and then split them open to look inside. They also make a musical shaker out of paper cups, a cardboard tube, and soybeans.
