This activity (on page 2 of the PDF under SciGirls Activity: Music and Sound) is a full inquiry investigation into sound frequency.

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

In this activity, learners construct a playable kazoo from inexpensive materials. They will experience how vibration creates sound waves and music.

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

In this activity, leaners build their very own rainsticks, an instrument filled with pebbles and seeds that create sounds like falling rain. Save costs by using material found around the home.

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.

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

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 math activity, learners play a game and identify patterns with fun moves and sounds. Discover how dancing and signing involve patterns.

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

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.

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.

Make a cuíca (“kwee-ka”), a traditional Brazilian musical instrument that originated in Africa. Played primarily in Brazil, now you can play it at home, too, with this Exploratorium produced activity.

Listen to the beat of gravity. By taking two strings with weights tied to them at different, yet uniform intervals, you can hear the uniformity (and rhythm) of gravity's accelerating pull.
