An awareness of the environment and its relationship to human health and efficiency are the focal points of this prototype curriculum for grades K-3. Assuming responsibility for creating and maintaining safe and healthy surroundings is urged. Specific curriculum content studies: (1) environmental factors (existing environment and effects, control, respect, appreciation, and pollution of the environment), (2) responsibility for a healthy environment in the school, home, and community, and (3) health professionals in the community. Appended material includes a chart indicating location of city, county, district, and regional health department offices in New York state and bibliographies of multimedia resources for teachers and students. This publication is one in a series of health curriculum materials devoted to environmental and community health (Strand IV). Four other strands deal with physical and mental health, sociological health problems, and education for survival. The format consists of four columns intended to provide teachers with: (1) a basic content outline, (2) major understandings and fundamental concepts, (3) teaching aids and learning activities, and (4) information about resource materials, sources, and personnel. Because of the comprehensive nature of the total curriculum, teachers are advised to become familiar with all strands presently in print. Related documents in Strand IV are ED 037 738-9, ED 049 477-8, and SE 016 280-6. (BL)
