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

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

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.
