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.

This is a quick activity (on page 2 of the PDF under Butterfly Wings Activity) that illustrates how nanoscale structures, so small they're practically invisible, can produce visible/colorful effects.

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

This is a quick activity (on page 2 of the PDF under Stained Glass Activity) about the "Tyndall effect," the scattering of visible light when it hits very small dispersed particles.

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

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 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 math activity related to light, learners assemble a photometer and use it to estimate the power output of the Sun.
