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.

Break open that used musical toy and squish some Play-Doh over the circuit boards, and you will hear some weird and distorted sounds the manufacturer never intended!

This activity requires a Pico Cricket (tiny computer).

This resource contains ideas and brief instructions on how to build animals out of construction paper and other simple materials.

A design challenge that takes paper airplanes into an entirely different direction: a magnus glider uses cups and and rubber bands to create a glider that uses the same forces that a curveball (from b

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.

Use grape juice, baking soda, water and vinegar to make acid and base indicator paper! This activity contains a recipe and instructions for the indicator paper.

In this activity, learners construct bug models that "jitter" all over the table with just a battery, motor, and counterweight.

This is a virtual representation of a sound mixer containing pre-looped sounds of animal, insect, and environmental noises.
