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

Can gelatin (like Jell-O ®) change the speed of light?

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

In this math lesson (on Page 13), learners predict and simulate the likelihood of an event occurring.

In this math lesson, learners extend their understanding of basic probability concepts as they learn to name all of the possible outcomes of an event as well as ways to express the likelihood of such

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

In this math lesson, learners identify the likelihood of an event by using a walk-on probability scale.

In this 7-10 day investigation, learners develop an understanding of waves and tides and their motion through discussion, demonstration, and hands-on activities.

In this outdoor activity and fun race, learners first find the most common type of tree in a forest site.

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

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

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

This activity generates learner excitement about light through the creation of a room-sized rainbow.

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.

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 build unique yo-yos, which spin round and round without moving up and down.

In this math lesson, learners measure, predict and determine the frequency of an event as it relates to how close Whirlybirds land to a target.

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

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 activity, learners explore sound by constructing a simple piano out of wood and craft sticks.
