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.

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.

In this activity, learners investigate the speed of chemical reactions with light sticks. Learners discover that reactions can be sped up or slowed down due to temperature changes.

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

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 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.

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.

Learners are challenged to discover the relative densities of colored liquids to create a rainbow pattern in a test tube.

In this activity, learners investigate the effect of heat on a reaction.

This is an activity about turbidity, or the amount of sediment suspended in water.

Learners are challenged to create solutions that conduct electricity and make a buzzer buzz (or an LED light up).
