In this activity, learners rotate through several learning and play stations to explore dinosaurs and paleontologists.

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

In this activity, learners create a xylophone by filling glasses with different amounts of water and tapping them with a metal spoon.

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 experiment with their voices and noisemakers to understand the connections between vibrations and the sounds created by those vibrations.

In this fun group activity involving music and movement, learners are introduced to the idea that many insects walk by using their legs to create "alternating triangles." Learners sing the "Ants Go Ma

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

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

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

In this activity, learners construct a traditional handicraft toy that illustrates a motion commonly associated with violins and earthquakes.

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

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

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, early learners create paintings by making music and rhythm. Learners place paper in cans, add paint-soaked beans (or pebbles) and put the tops on.

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

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

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