Creative ways to use the outdoors as a part of the regular school curriculum are outlined in this teacher's manual for the elementary grades. Presented for consideration are the general objectives of outdoor education, suggestions for evaluating outdoor education experiences, and techniques for teaching outdoor education. The purpose and functions of a mobile unit--designed as a workshop, library, and laboratory to aid teachers--are discussed, and a list of equipment available on the unit (e.g., compasses, maps, and binoculars) is presented. The major portion of the manual lists outdoor education concepts by subject matter and grade level and suggests ways the concepts can be incorporated in the everyday curriculum. (DB)
