This manual, developed with a grant from the United States Office of Education, Office of Environmental Education, contains ten interdisciplinary environmental education teaching units developed by teachers from the state of New York for use in the secondary grades. The units are referenced to the syllabuses of New York State and are designed to supplement or supplant some of the units normally used in instructional programs. The format of this publication is designed to facilitate the duplication of subject matter segments, individual worksheets, or single units. Units are provided for consumer education, English language arts, environmental studies, fine arts, health, industrial arts, mathematics, sciences, and social studies. Learning activities within individual units contain syllabus and environmental references, objectives, procedures, related activities and resource materials. The appendices consist of: (1) a schematic of a curriculum design process; (2) categories of environmental issues; (3) environmental education instructional objectives; (4) environmental concepts defined; (5) environmental understandings; (6) an annotated list of other New York State Education Department environmental materials; and (7) a list of New York City curriculum references for the units in this manual.
