This resource from the Teach Engineering website is designed to help students learn about water quality testing and basic water treatment designs. This resource was created by scientists at the Integrated Teaching and Learning Program in the College of Engineering at the University of Colorado at Boulder. Users will find ten different sections that cover the learning objectives, vocabulary, associated activities, and assessment. The entire exercise should take twenty minutes in the classroom, and the features here include graphs, charts, helpful annotated photographs, and so on. The exercise may be used to raise awareness of the importance of clean drinking water in the developing world and how various innovations can help in achieving this goal.
