This teacher's guide is for an environmental education module to integrate topics of water quality in ninth- and tenth-grade social studies classes. This module was pilot tested in Gwinnett County, Georgia in 1975-76. Included in the guide are overall objectives, the module sequence, an introduction, a suggested teaching sequence, a word review game, and review and reading exercises. The module sequence is divided into four parts. The first part provides an introductory episode to stimulate student interest in an environmental issue concerning water. The second part is designed to improve understanding of water resources and treatment. The third part develops social studies concepts around examples from the county community. In the fourth part, the student applies what he/she has learned to prepare a publicity project. This module is intended to go with a similar one in ninth- and tenth-grade chemistry classes. (BB)
