In this demonstration, learners observe the effects of density and pressure. A "diver" constructed out of a piece of straw and Blu-Tack will bob inside a bottle filled with water.

In this environmental science activity, learners research what is essential for plant life and the necessary components of soil to support plants.

Millions of organisms can live in and around a body of water.

In this activity, learners explore how salt water freezes in comparison to fresh water.

In this activity, learners work in small groups to match various marine animals with their different environments.
