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

In this activity, learners use Jell-O to explore lenses. Learners cut Jell-O into convex and concave lens shapes and examine how light exits each lens in a darkened 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.

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

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

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 will explore vegetative propagation while preparing food scraps to grow into plants.

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.

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

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.

Learners follow directions to construct a solar oven that really cooks! The solar oven uses aluminum foil to reflect sunlight into a cooking chamber, which is painted black.
