In this activity, learners use their strength to light a light bulb. A chain made from paper clips is placed in series with a battery and flashlight bulb.

In this activity, learners make prisms from gelatin. Learners then shine light through the prisms and discover what happens. This activity introduces learners to the idea of refraction.

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

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

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

In this activity, learners investigate how some butterfly wings get their color.

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

Use this model to demonstrate the goal of NASA's Kepler Mission: to find extrasolar planets through the transit method.

In this outdoor activity, learners explore UV rays from the Sun and ways to protect against these potentially harmful rays.

In this activity, learners explore the principles of magnetism by observing how various materials interact with magnets and superconductors.

In this activity, learners light an LED with five cents. Learners use two different metals and some sour, salty water to create a cheap battery.
