This handbook has been designed as a teaching resource to be used in the development of student attitudes and competencies, reflecting an awareness of the environment, and a motivation to work toward solutions to its problems. Listed activities are to be adapted to the abilities and interests of students, school locale, and teaching situation. Suggested exercises consist of air, noise pollution, soil, rocks, minerals, ecosystems, trees, plants, marine and freshwater life, animals, population, energy, pesticides, land use, watershed management, private enterprise, student needs and perceptions, and solid waste. Each of the activities or encounters has objectives stated in behavioral terms. The rationale for each undertaking is identified, with needed materials and appropriate terminology. The environmental topics are divided into activities which call for some particular action on the part of students (i.e., observation, collection, identification, comparison, discussion, etc.). Appraisal activities are suggested for teachers to determine the extent of learning which has occurred. The encounters have been made as flexible as possible to give them the greatest utility. They are designed to be implemented in one or more of the curricular areas, and suggestions for integration are provided. Printed and audiovisual materials are also listed. (BP)
