In this activity, learners explore what happens when polarized white light passes through a sugar solution.

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

In this activity, the learner will experiment with the physics of sound production while making a sound making toy. The activity includes a video with step by step instructions.

In this activity, learners observe what happens when they give a light source like a neon glow lamp a "Bronx Cheer." The lights appear to wiggle back and forth and flicker when learners blow air throu

In this quick activity (page 1 of the PDF under SciGirls Activity: Extreme Sounds) about sound vibrations, learners will investigate which small objects, such as coins, hex nuts, or marbles, produce t

In this outdoor activity and/or field trip, learners investigate the behavior of hopping animals.

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.

Learners build pan pipes out of drinking straws by cutting them to different lengths. Then, learners make music by blowing across the straws and playing some well-known songs.

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

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

Sound can travel through a variety of media.

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 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, learners explore how polarizing sunglasses can help diminish road glare.

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

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