In this optics activity, learners use a shoebox, colored cellophane and sunlight to "change" the colors of gumballs. Learners will be surprised when the green and blue gumballs appear black!

In this optics activity, learners explore how they can make gelatin stop light, but not stop them from seeing fruit suspended within.

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

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

In this sunny day activity, learners compare how a cup of water and a cup of tonic water reflect or refract light in the sun.

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

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 outdoor, winter activity, learners find living green plants under the snow and determine the light and temperature conditions around the plants.

In this demonstration, adult learners create a lava lamp using beer and nuts! Use this pub-themed activity to demonstrate the effects of buoyancy and bubbles.

In this activity, learners create a "mini sky" in a glass of water in a dark room.

In this activity (1st activity on the page), learners explore their sense of taste and the structure of the tongue by taste-testing various foods.

In this quick activity, learners observe how the added sugar in a can of soda affects its density and thus, its ability to float in water.

This is a highly visual demonstration that illustrates both the effects of density and chemical reactions.
