Included in this guide are ideas on evaluation and conduct of outdoor education classes and unit guides and lesson plans. An interdisciplinary approach is emphasized and the unit guides and lesson plans present activities related to science, mathematics, social studies, art, and music relevant to outdoor education in general. Unit guides for soil, water, forestry, and "balance of nature" are given, usually for primary, intermediate, junior and senior high school grades. Lesson plans suggest how these topics may be studied. Supplemental material describing plant and animal communities include many activities suitable for outdoor use. A bibliography of conservation, outdoor education, ecology texts and field guides is included. This work was prepared under an ESEA Title III contract.
