Make a kite out of a garbage bag, shower curtain, painting tarp--anything light, thin, flexible and plastic!

In this activity, learners will create an optical illusion top. Learners will explore color mixing, physics and design through this activity.

Learners experiment with a commercially available liquid-crystal coaster. They warm the material with their hands for varying lengths of time and observe the changing colors that result.

In this activity, learners construct a device that allows them to look over ledges or around corners.

This fun activity uses simple materials such as milk cartons and mirrors to introduce the ideas of optics and visual perception.

In this activity, learners construct a device that allows them to view 2-D images in 3-D.
