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

In this activity, learners explore color, light and shadow by creating their own puppets to hold in front of a light source.

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.

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.

With a laser pointer and some household items, learners can create their own laser light show. They can explore diffuse reflection, refraction and diffraction.

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.

In this amazing activity about light and reflection, learners will use a pie plate and reflective strips from a mylar balloon to try to morph their face into a friend's.

In this activity, learners explore why they can see colors in bubbles and why they change.

Can gelatin (like Jell-O ®) change the speed of light?

In this activity, learners experiment with shadows and light sources to understand the relationship between the angle illumination and the shadow's length.

In this optics activity, learners work in pairs to explore how mirrors work. Learners use tape to mark the angles needed to see each other's reflection in a wall mirror.

In this activity, learners compare and contrast different forms of luminescence by observing how chemiluminescence, phosphorescence, and fluorescence produce or emit light.

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

Learners demonstrate how water can distort, refract and magnify light.
