This unit, intended for grades five and six, includes a group of experiences designed to help students and the teacher understand society's effect on their environment and to parallel the activities in the classroom as a miniature society with life outside the school. The main idea developed is that cooperation is the key word in man's interaction with others and his environment. Among the ten concepts discussed are cooperation between society and the total environment, the need for conservation laws, valuing and freedoms. Besides the ten concepts, the unit includes behavioral objectives which are identified by concept, a pre- and post-test, background information designed to help the teacher effectively deal with attitudes and values, and a suggested instructional sequence. A bibliography is also presented. (TK)
