In this activity, learners make prisms from gelatin. Learners then shine light through the prisms and discover what happens. This activity introduces learners to the idea of refraction.

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 discover what happens when they crush wintergreen-flavored candies in a very dark room.

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

In this activity, learners use a flashlight, a glass of water, and some milk to examine why the sky is blue and sunsets are red.

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

In this activity, learners sublimate dry ice and then taste the carbon dioxide gas.

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 make optical fibers out of strips of gelatin.

In this laboratory activity, learners design an experiment to evaluate how environmental factors influence the growth of molds.

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, learners conduct a series of hands-on experiments that demonstrate how the working of plants' veins, known as capillary action, enables water to travel throughout the length of a pla

In this activity, learners will explore vegetative propagation while preparing food scraps to grow into plants.

This is a classic exercise for visualizing the scale of the Solar System.

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.

Learners build a solar oven from a cardboard pizza box, aluminum foil and plastic. Learners can use their oven to cook S'mores or other food in the sun.

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