This is the teacher's guide for a learning module designed to integrate environmental education into ninth- and tenth-grade social studies classes. This module and a parallel module designed for chemistry classes were pilot tested in Gwinnett County, Georgia in 1975-76. The module is divided into four parts. The first part alerts students to the serious problems that growth and development can bring to the environment and provides an ecological setting for analyzing alternative solutions. The second part provides factual information and various perspectives on population growth and the ways in which it has changed the county community. In the third part, waste collection and disposal and its relationship to land use planning, community health, and the quality of life are analyzed through a series of readings and activities. The fourth part introduces basic principles of careful land use as a means of preventing environmental decay. The teacher's guide gives overall project objectives, the module sequence and supplemental materials, and suggested short-answer review quizzes. (BB)
