Introduce young scientists to the fundamentals of environmental engineering with a nine-resource collection that looks at air, land, and water quality concerns. The unit begins with a PowerPoint presentation that provides background information on environmental issues. The focus then shifts to water pollution, its causes, and what can be done about it. Labs provide hands-on experiences that permit learners to gain an understanding of the chemical properties of water and how it interacts with other liquids.
