This guide is intended for use as a supplemental science teaching aid with students having diverse medical, learning, and/or behavioral problems in either self-contained or regular elementary classes. Its purpose is to teach observation skills and the scientific method, to stimulate thinking, and to increase interest in science and related academic areas. The 29 specific activities presented in the guide are grouped into sections addressing physical, earth, and life sciences respectively. Each section provides a general description of a specific area of science; lists objectives, activities, materials, and vocabularies; and provides supplemental activity ideas. Listed for each activity are the objectives, materials needed, activity steps, and discussion ideas. Also provided are general suggestions about behavioral management, testing and grading, and scheduling and lesson plans. Appendices include: a list of science objectives; safety rules; materials; steps of the scientific method; a description of the language experience approach; a summary of behavior management techniques; sample success notices (for reproduction); a sample contingency contract between student and teacher; and a listing of five teaching resources.
