Water on Earth is in lakes, the ocean, rivers, underground, and frozen glaciers.

Some aquatic organisms live in open water, while some live in soil at the bottom of a body of water.

In this activity, learners make water rockets to explore Newton's Third Law of Motion. Learners make the rockets out of plastic bottles and use a bicycle pump to pump them with air.

In this activity, learners examine photo images of Earth taken from space, and attempt to identify and explain some of our planet's geological features.

This activity provides a hands-on experience with a scale model, a relatively high viscosity fluid, and feeding behaviors.

Learners build a filter from old soda bottles and dirt. They create polluted water, and pour it through their filter to clean it.
