Backpacking serves as the vehicle for teaching basic secondary school subjects in this curriculum guide which suggests various learning activities for teaching human relations, environmental education, and camping. The activities, some for the classroom and some for the trail, are designed to help students observe, draw conclusions, and develop fundamental reasoning skills. The guide begins with a section for teachers about trip planning and organization, group dynamics, outdoor teaching strategies, recreational activities, and environmental values. The following four sections contain units for students under the headings of human relations, natural environment, humanizing camping, and camping skills. Each section contains numerous subtopics each with background information for students, concepts, objectives, and learning activities. The human relations section contains 10 subtopics including value systems, trail dilemmas, and effective leadership. The natural environment section provides 35 subtopics in the areas of astronomy, geology, ecology, fauna, flora, and weather and climate. The section titled "Humanizing Hiking" covers southern California history and culture as well as the verbal and graphic interpretation of outdoor education experiences. The camping skills section covers campsites, equipment, first aid, camp food, personal conditioning, trail safety, survival, and maps. The appendix provides a bibliography of nearly 200 references.
