This book was developed for use in India and is adapted from "Ideas for Science Investigations" by Victor M. Showalter and Irwin L. Slesnick. It is a source book of ideas for student research projects. Three model projects are described, illustrating different approaches taken by three students to the investigation of the rise of sap in plants. These include realistic descriptions of searching for information, formulating the attack on the problems, maintaining records, and reporting results. In the next section, over 100 phenomena or situations are described, each with a series of questions suitable for experimental investigation. Most topics are arranged alphabetically with no attempt to classify them according to traditional science disciplines; many are interdisciplinary. References are given to sources of ideas, techniques and background information. (EB)
