The 10 lessons in this manual for secondary school teachers address concerns ranging from water sources and pollutants to government programs and water treatment methods. The materials are intended to help students understand the sources of drinking water, how water can be made safe for drinking, and the health threat that contaminated water represents. Although this curriculum relates primarily to science, health, and social studies lessons, the follow-up activities also involve skills developed in art and English classes. Each lesson plan contains a materials list, general introduction, vocabulary, instructional activities, and suggested supplementary activities. Included with the lesson entitled "Alaska's Water Sources and Problems," are detailed data from each of the state's regions. (Author/WB)
