Contained are instructional materials developed by the Science Project Related to Upgrading Conservation Education. The lesson plans given are intended to demonstrate the "indoor-outdoor-indoor" approach to teaching science conservation, with concentration on methods of inquiry and emphasis on processes of science. Four subject areas are treated: Air, Water, and Weather; Living Things; The Earth and Its Composition; and Our Growing Bodies. One plan is given for each area for each of grades K-3. The plans list materials required, set problem questions, then describe indoor and outdoor activities to help students discover answers to the questions. Relevant science concepts and conservation concepts are listed. The manual also lists the objectives of "Outdoor Discovery Guides," and given an example guide. There is a summary of the goals of the program, together with general guidelines for teaching and selected references for the teachers. This work was prepared under an ESEA Title III contract. (EB)
