This document has two parts. Part I is a rationale developed to present a point of view about the opportunities for environmental education in urban schools. The premise is that environmental education should be a vital part of the total school program. Part II, Teaching Activities, contains ideas and suggestions for implementing such a program. The activities are designed for student use in grades K-12. Each activity has been classified according to the most appropriate grade level, subject matter, environmental concept involved, and environmental problem area. In addition to being classified in these four categories, each activity contains: (1) a statement of purpose on how the activity may be used, and (2) a reference to a source where the activity may be found in more detail or with variations.
