Learners observe different paper samples under ordinary room light and under a black light to learn some of the chemical differences between different types of paper.

In this activity (posted on March 12, 2011), learners follow the steps to construct a spectroscope, a tool used to analyze light and color.

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

Learners mix a solution of luminol with hydrogen peroxide to produce a reaction that gives off blue light.

Learners experiment with a commercial photo-sensitive paper (Sunprint® or NaturePrint® paper). They place opaque and clear objects on the paper and expose it to bright light, observing the results.

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

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.

This is written as a display, but can easily be adapted to a hands-on activity. Learners observe and shake containers of shiny liquids.

In this two-part activity about luminescence, learners explore the chemistry that happens inside glow sticks and other light producing reactions.

In this activity, learners make a photographic image—without a camera!

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

In this activity, learners use simple materials to create giant bubbles.

In this activity on page 7 of the PDF (Plants—The Green Machines), learners examine the effects that light and air have on green plants.

Working in groups, learners model the continuous destruction and creation of ozone (O3) molecules, which occur in the ozone layer.

In this activity, Frankenstein's lab is running out of electricity! Learners use fruit to help Igor find a temporary source of energy to turn on a light.

In this activity, learners use earthworms as "unknown creatures" from the South American jungle to find out how animals use senses.

In this activity, learners investigate the properties of graphene and graphite.

In this activity, learners will make homemade jello that glows under a blacklight. They will learn about quinine, an ingredient in tonic water that is fluorescent.

Construct a simple battery that's able to power a small light or motor out of foil, salt water, and charcoal. A helpful video, produced by the Exploratorium, guides you along on this activity.
