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.

In this activity, learners observe, explore and investigate vibrating instruments in everyday places and create music in unique ways.

In this four-part activity, learners explore light and sound through a variety of hands-on investigations.

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, learners explore sound by constructing an instrument toy that buzzes when you swing it.

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.

In this activity, learners experiment with their voices and noisemakers to understand the connections between vibrations and the sounds created by those vibrations.

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

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

In this activity, learners explore sound by constructing their very own instruments using PVC pipes, soda bottles, and a straw.

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, learners build a cuica or chirping bird using straw, string, and a bottle cap. Use this activity to explore the interplay of motion and sound.

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.

In this activity, learners explore sound by constructing their very own bagpipe 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.

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 activity, learners explore sound by constructing an instrument using some metal pipes, rubber bands, and a baseboard.
