The purpose of this publication is two-fold: to show how the natural features on campuses can be used effectively in environmental education and to plead for preservation of as much of the natural landscape as possible on new school sites. Since opportunities for teaching about nature are easily found on the grounds around a school, this booklet outlines briefly some of the ways teachers can make the most of this opportunity, and gives sources for additional material and assistance. Campus and program development discusses the outdoor site, classroom preparations, and project ideas built around the history of conservation, plant life, animal life, nonliving elements of the environment, light, water, weather, temperature, soil, minerals, and fire. Trails, signs, amphitheaters, ponds, weather stations, and models that can be built or developed at the outdoor learning facility are enumerated under teaching aids. The final section suggests additional projects which can be undertaken with little preparation necessary--leaf identification, snow study, animal food habits, habitats, fireplace construction, cooking, compass skills, insects, clouds, measurement, growing plants, seeds, birds, trees, soil study, moisture and rain gauges, pond life, food manufacturing, decomposition, climbing plants, and woodlands. A bibliography is appended. (BL)
