In this activity, learners design, build and test wind turbines. Learners go through the design process and use the scientific method to test important blade variables.

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

In this activity (page 95 of the PDF), learners create Escher Staircase models similar to those that were used by Neurolab's Spatial Orientation Team to investigate the processing of information about

String Thing is an interactive online game in which learners change a virtual string's tension, length, and gauge to create different musical pitches.

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 create music from a series of bottles filed with water. Learners discover that the sound produced by each bottle depends on the amount of water in the bottle.

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

With three cans and some tape, make a drum that you bonk down on any surface to produce a variety of sounds. This activity also teaches you about pitch, vibration, and frequency.

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

In this environmental engineering activity, learners build windmills using everyday items. The first challenge is to build windmills that spin when placed in front of a fan.

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