This resource book includes 163 science activities for both preservice and in-service teachers. Activities have been field-tested and are cross-referenced according to the processes of science and the content area covered. Each activity has been written to evoke ideas from the reader, thus enabling each activity to serve a base for additional activities. The first part of this book contains "bis" activities--"Brainstorming in Science" activities. The extension of these activities can be developed into science, technology, and society issues. The second part, "Shoestring Sciencing," deals with doing more science for less money. Activities are classified by related subject areas and science skills. The appendix presents a Celsius-Fahrenheit conversion table, a metric system table, and a metric-imperial equivalents table. (KR)
