This guide to environmental and outdoor education is based on the principle that man will properly care for his world only if he both understands and appreciates it. Seventy-two multidisciplinary environmental themes are identified for instruction in grades K-12. Each theme is presented with behavioral objectives, key concepts, and both in school and out of school activities. The outdoor activities are heavily emphasized, and designed for a local nature center, public parts, and campgrounds. Disciplines incorporated together and separately in the themes are: science, social studies, math, and humanities. The guide recommends that the themes be taught in conjunction with the regular curricula, when appropriate. Supplementing each theme group (K-3, 4-6, and 7-12) are extensive resource guides to films, recordings, filmstrips, pamphlets, and books. A final section presents ideas and information for teachers in planning outdoor experiences, such as: literature and music for the outdoors, and how to read a compass. (DJB)
