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.

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.
