Learners test their "light-smarts" by playing a game called "Light Quest!" The game board represents an atom and each player represents an electron that has been bumped into the atom's outer unstable

This simple hands-on activity demonstrates why the sky appears blue on a sunny day and red during sunrise and sunset.

In this four-part activity, learners explore light and sound through a variety of hands-on investigations.

In this four-part activity, learners will discover the exciting world of light--the most important form of energy in our world--and be able to identify and describe different types of light.

In this activity, learners use gelatin as a lens to investigate the properties of laser light.

In this activity, learners use transparent tape and polarizing material to create and project beautifully colored patterns reminiscent of abstract or geometric stained glass windows--no glass required

In this activity, learners explore why the sky is blue. Learners model the scattering of light by the atmosphere, which creates the blue sky and red sunset, using a flashlight and clear glue sticks.

Learners examine the properties of light by experimenting with an LED-flashlight and polarizing filters. When two polarizers are used, they block all light when they are placed at right angles.

In this activity, learners explore what happens when polarized white light passes through a sugar solution.

In this optics activity, learners explore why the sky is blue and the sunset is red, using a simple setup comprising a transparent plastic box, water, and powdered milk.

In this optics activity, learners create a ripple tank from household materials to study waves. Learners build the tank and then explore by making various types of waves.

In this activity about light and perception, learners create and observe moire patterns.

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

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

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

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

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

This is an activity about waves. Using marbles, paper clips and rubber bands, learners explore how waves behave.

In this optics activity, learners explore interference by adding wax blocks to a ripple tank.
