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

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

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

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.

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.

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

In this math activity, learners use gingerbread cookies to collect and organize simple data. First, learners read "The Gingerbread Boy" by Paul Galdone.

In this activity, learners will listen to as many radio stations as possible to discover that AM radio signals can travel many hundreds of miles at night.

In this math lesson, learners apply the Monte Carlo method of simulation to determine a reasonable estimate.

In this math lesson, learners participate in a variety of activities that give them experience in recognizing, describing, and extending repeating and arithmetic patterns.
