This guide is written to focus attention on both the cognitive and affective aspects of environmental education. Its format provides four levels of development: primary, intermediate, junior high, and senior high school grades, with the first two subdivided into three categories each. Performance objectives, teaching-learning inquiries, and evaluation-terminal performance are outlined within each level based on three supporting concepts. These concepts emphasize interdependence in interchange of matter and energy, in social interaction, and in cultural components and forms. Basic ideas accentuated throughout the activities are that: (1) increased population growth creates a population pressure on the carrying capacity of our ecosystem, and (2) the consumption of goods and services per capita places an increased pressure on our renewable and non-renewable resources. Topics cover land, air, water, ecology, plants and animals, environment, and population and the approaches to these topics; concepts stress awareness, concern, and action. A bibliography, agency resource list, glossary of terms, and additional teaching-learning activities are appended. (BL)
