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, learners build their own sound machines and explore the interplay of motion and sound.

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.

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

In this activity, learners explore how an electromagnet works by making a simple one. Using this knowledge, learners design a diagram to make a working speaker using household materials.

Sound can travel through a variety of media.

This is a series of three quick science activities to do with a spoon, knife, and fork. In the first two activities, learners use the flatware to explore optics, mirrors, reflection, and distortion.

In this activity, learners turn an ordinary metal coat-hanger into a (very quiet) musical instrument.

In this activity, learners build a slide whistle using PVC pipe, bamboo skewer, and piece of foam. Construction of the instrument is relatively simple.

Build a phonograph record player using a cactus needle, a record, LEGOs gear box, and a piece of paper! This activity uses a Pico Cricket to turn the motor.

In this quick activity (page 1 of the PDF under SciGirls Activity: Music and Sound), learners will construct an oboe-like instrument from a plastic drinking straw by cutting the end to split it into t

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 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).

In this quick and easy activity, learners build an air cannon "drum" and see what happens when they "shoot" puffs of air at different targets.

In this activity, learners explore sound by constructing their very own banjo out of a coffee can. Learners experiment with the canjo to change the instrument's pitch and timbre.

Make your own simple speaker so you can listen to your favorite radio station. Just wind a coil, attach it to a piece of cardboard or Styrofoam, hold a magnet nearby, and listen.

Oboes's unique sound originates from the two small reeds a musician blows into. Make your own double reed instrument out of straw!

Things that are different sizes and stiffness vibrate differently, and in this Exploratorium Science Snack, you'll see how rings of various diameters react to vibration and external forces.

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.
