Promoting understandings in outdoor science and conservation is the primary goal of the Los Angeles County Outdoor School as presented in this guide to its five-day resident program for elementary school pupils. The purpose of various program components is briefly described, including hikes, cabin living, campfires, conservation projects, crafts, dining hall, evaluation and planning, flag ceremony, folk dance and folk singing, library and museum visits, and specialists. A sample daily schedule gives approximate times for a typical day. The 1973-74 curriculum is outlined under four major concepts: (1) an ecosystem consists of natural communities of plants and animals interrelated and interacting with their physical environment, (2) man's attitudes and way of life create an ecological impact on the environment; man's survival depends on his ability to minimize this impact, (3) the earth is in constant motion producing regular predictable changes in the environment to which man adapts, (4) outdoor school is a minicommunity in which each pupil can participate as a citizen and creative person. Under each, activities to accomplish objectives are given, with both outdoor school and classroom learning opportunities, many of which provide for multicultural experiences. The appendix has a glossary in both English and Spanish and site information on the outdoor school. (RS)
