In this activity, learners discover how to determine the distance to a lightning strike or nearby thunderstorm.

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

This activity (on page 2 of the PDF under SciGirls Activity: Extreme Sounds) is a full inquiry investigation into sound.

Make your own speaker with a magnet, wire, and paper cup! If you have a radio with a headphone plug and an old pair of headphones, this is a great tinkering activity.

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.

Audio Boggle is an activity that lets you listen to a track (that you make yourself) and see what you can hear!

Learners make bell bracelets, place them on their wrists or ankles, and then dance to the rhythms and sounds the bells make. Many cultures use ankle or wrist bells to make music during dancing.

In this activity, learners imitate the way vocal cords work by building a model from a plastic cup, rubber band, and a straw.

What's a Pickle-Oh? Two pieces of pickle on a stick are connected to a Pico Cricket (micro controller). When you slide the pickles apart the note changes.

Use echolocation to find others and experience how whales’ senses have adapted to suit their environment. In pairs, learners are blindfolded and use containers filled with marbles to find each other.

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

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.

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.

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

Create an instrument that you don't play--you just listen to it through tubes of various lengths.

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

Focus sound through a balloon! In this Exploratorium activity, you'll use dry ice to create a balloon that's a sound lens.

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.

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.

In this design challenge activity, learners add headphones to a previously built instrument (see "Build a Band" activity) to make it easier to hear.
