In this activity, learners use an old CD to construct a spectroscope, a device that separates light into its component colors.

In this activity, learners explore how nanosized structures can create brilliant color.

In this activity, learners discuss and investigate how cameras, telescopes, and their own eyes use light in similar ways.

In this activity about light and perception, learners create pictures in thin air.

In this optics activity, learners examine how a transparent material such as glass or water can actually reflect light better than any mirror.

In this optics activity, learners make a "light fountain" from a clear plastic bottle, flashlight, and other simple materials.

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 look over ledges or around corners.

In this optics activity, learners use glass and water to demonstrate total internal reflection (TIR).

In this activity, learners explore liquid crystals, light and temperature. Using a postcard made of temperature-sensitive liquid crystal material, learners monitor temperature changes.

In this activity, learners explore how polarizing sunglasses can help diminish road glare.

In this activity, learners use a laser pointer, empty soda bottle, rubber plug and water to demonstrate total internal reflection.
