Designed as enrichment materials for grades six through nine, this program is an interdisciplinary study of soils. As part of the program students: (1) examine soil organisms; (2) research history of local Native Americans to see how they and others have used the land and its soils; (3) investigate how soils are degraded and how they are conserved for future use; and (4) investigate several critical issues that will affect their lives and the lives of others. "Conserving Soils" consists of 24 spirt duplicating masters, four full-color transparencies, and a 16-page teacher's guide. Each activity master (discussed in the teachers's guide) will produce a minimum of 200 copies. Each of the four transparencies is a full-color illustration, presenting a soil ecosystem, soil profile, soils map, and land use planning map. The teacher's guide contains the background information needed to introduce and teach each lesson. Objectives and suggested activities for getting students actively involved in the learning process are printed on the non-producing side of each spirit master. Techniques include out-of-class research, small group discussion and decision-making, brainstorming, experiments, and case study investigations both in class and outdoors. A glossary of important terms for student and teacher use is also provided. (Author/JN)
