Using experience gained while helping elementary, junior high, and high school teachers plan, develop, and use thousands of outdoor classrooms, the Alabama Soil Conservation Service (SCS) produced this teacher's manual for outdoor classrooms. Emphasis is on conservation education and the environment and man's relationship to it. Rationale for developing an outdoor classroom, preferably as an integral part of the school site, includes: training in environmental responsibility, expanded learning opportunities for all students, real learning experiences, effective means of teaching conservation. The manual suggests how SCS can help the teacher and outlines steps for beginning an outdoor classroom (including community cooperation, common pitfalls, and 46 specific features that could be incorporated). Activities listed describe how an outdoor classroom may be used in science (animals, aquatic studies, chemistry, ecology, home economics, geology and soils, plants, vocational agriculture, weather), mathematics, social studies, language arts, art, music, shop, P.E., health and safety, journalism, clubs. The appendix contains a glossary; a list of basic visual and written references and organizations providing free or inexpensive materials; and illustrated teaching aids on the tree, roots and rings, grass and grasshoppers, monarch butterfly, use of the microscope, and bird feeders.
