In this lesson, students will explore the causes of water pollution and its effects on the environment through the use of models and scientific investigation. In the accompanying activities, they will investigate filtration and aeration processes as they are used for removing pollutants from water. Lastly, they will learn about the role of engineers in water treatment systems.

To benefit society, engineers design and build systems to keep our global water supplies clean. This requires that engineers investigate the water source, and route it travels before it is used by people, and study previous methods that have successfully cleaned our water supplies. Understand the role of engineers in water treatment systems.Understand how contaminants leach into the soil and ground water and how they are absorbed by plants. Understand the natural water filtration process. Examine how much water is consumed by humans in a lifetime.
