This is a teacher's guide for a learning module designed to integrate environmental education into ninth- and tenth-grade chemistry classes. This module and a companion social studies module were pilot tested in Gwinnett County, Georgia in 1975-76. The module is divided into four parts. Part one provides a broad overview of unit content and proposes questions to stimulate student interest in environmental problems. Part two is intended to develop understanding of population dynamics. Part three deals with population and land use. Part four addresses the problems of waste disposal. This guide includes overall objectives, the module sequence, teacher preparation for class activities, suggested sequence of instruction, and suggested short-answer review quizzes. (BB)
