This publication is the first volume of curriculum resources published by the Kalamazoo Nature Center. It contains directions for using the curriculum activities guide and suggests ways of implementing the activities in the classroom. Also included is an outline of the material that could be covered in an environmental education program, with appropriate activities. The bulk of the publication is devoted to over 300 pages of learning activities suitable for secondary school students. Each activity provides a short introduction, a listing of materials needed, the procedure, some discussion questions, and a bibliography. Topics covered by the activities include land use, natural resources allocation and depletion, energy use and conservation. Indexes at the end of the guide classify activities according to study topics, subject teaching areas, grade levels, activity titles, and activity numbers. (MA)
