Water Treatment: How Can We Make Our Water Safe to Drink

A project of the National Science Foundation, ChemConnections modules use guided, discovery-based learning activities to promote a deep understanding of a broad range of chemistry concepts and problem-solving techniques. Each module poses a central question for example, What’s in a Star? or How Can We Make Our Water Safe to Drink? that students investigate through guided discussions, collaborative laboratory work, reading and writing assignments, case teaching, policy simulations, Web research, and videos.
