In this lesson students investigate what happens when people’s activities result in water pollution. Pollution on land is simulated with the addition of easily obtained materials in a clear bowl of water. Students make links with retaining healthy waterways with preventing polluting substances from reaching them.

Students investigate the interconnected relationships within a simplified food web. Students deduce the impact on the food web when components are changed.

In this experiment, students make a rocket using a film canister, an antacid tablet and water. Through this experiment, students will understand that mixing materials can result in a variety of consequences.
