In this chemistry activity, learners are asked to form a hypothesis about the behavior of milk as household detergents act upon it.

The "Rocket Reactions" activity is an exciting way to learn about how materials interact, behave, and change.

In this chemistry activity, learners use spaghetti to explore density and chemical reactions.

Learners add acid rain (nitric acid) to two cups that represent lakes. One cup contains limestone gravel and the other contains granite gravel.

Extract your DNA from your very own cells! First, learners swish salt water in their mouth to collect cheek cells and spit the water into a glass.
