This learning module is 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 an understanding of population dynamics. Part three deals with population and land use. Part four addresses the problems of waste disposal. The module is intended to take 16 or 17 days to complete. Some of the activities included are a population study using microbes, a study of symbiosis, soil moisture and percolation rate, and a simulated zoning board meeting. (BB)
