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.

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

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, 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 explore how polarizing sunglasses can help diminish road glare.

In this activity best suited as a demonstration, learners observe that when a piece of iron gets too hot, it loses its ability to be magnetized.

In this activity, you'll use a paper cup, a piece of cloth, and some string to make a musical instrument called a cuica (pronounced KWEE-kah).
