In this activity related to light and perception, learners use a pinhole in an index card as a magnifying glass to help their eye focus on a nearby object.

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

This activity generates learner excitement about light through the creation of a room-sized rainbow.

In this optics/mathematics activity, learners use two hinged mirrors to create a kaleidoscope that shows multiple images of an object.

In this activity, learners explore the relative efficiency of different bulbs, specifically incandescent vs. fluorescent.

In this activity, learners explore the invisible infrared radiation from an electric heater.

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

In this optics activity, demonstrate diffraction using a candle or a small bright flashlight bulb and a slide made with two pencils.

If you have lights, cardboard, scissors, and some brass fasteners, you can make shadow puppets! Create a story-telling and design challenge for your learners with this simple and creative activity.

In this activity, a lightbulb is placed in front of a concave mirror. The actual lightbulb is not visible to the viewer, but the viewer can see the mirror image of the lightbulb formed in space.

In this activity, learners will make their own prism and use a glass of water to separate sunlight into different colors.

In this activity, learners explore chemiluminescence and fluorescence. Learners examine 3 different solutions in regular light, in the dark with added bleach solution, and under a black light.

In this activity about light and refraction, learners discover how a lens creates an image that hangs in midair.

In this optics activity, learners examine how polarized light can reveal stress patterns in clear plastic.

In this optics activity, learners explore how many objects they can see in a set of mirrors (hinged like a book) at various angles.

In this activity, learners will create their own simple shadow puppets, and experiment with light and shadow while playing with them.

This activity provides instructions for building a mirrored tube--a smaller and simpler version of a submarine's periscope--that lets you see around corners and over walls.

In this activity, learners will build a model of a nebula using cotton balls and colored water. Astronomers photograph nebulas and add colors to provide information about the nebula's composition.

In this two-part activity, learners explore the properties of liquid crystals, which are responsible for why mood rings change color.

In this food science activity, learners conduct an experiment that demonstrates the importance of light to plants.
