In an effort to provide teachers in Ohio with assistance in environmental education, the Ohio Environmental Protection Agency (EPA) has produced this teachers kit. It is designed to describe what the Ohio EPA is doing to protect Ohio's air, land, and water. The background information provides an historical account of some of the events that have taken place in the past 20 years, and describes the Ohio EPA's current efforts in the areas of air, land, and water pollution control, as well as the agency's emergency response program. This guide includes: (1) suggested projects and activities for students in the elementary grades; (2) a list of suggested field trips; (3) ideas for community participation; (4) a description of the Ohio EPA speakers bureau; (5) a list of other Ohio EPA brochures available and planned; (6) addresses and phone numbers of local air pollution control agencies; and (7) a list of other organizations and agencies involved in environmental education.
