School Library Journal - School Library JournalGr 6-9-Those looking for demonstrations of scientific principles will find unique experiments here. Each chapter introduces a new topic and contains several experiments, followed by a page of "Project Ideas and Further Investigations." Safety tips and warnings, which include asking for adult help, appear in both titles. Materials needed are listed in shaded boxes and are generally easy to obtain, and the large, clear, captioned diagrams assist in explaining concepts and showing how to re-create the activities. Fish Tank addresses "Cohesion, Adhesion, and Capillary Action"; "Surface Tension"; "Floating and Sinking"; and more. Experiments can be done with fish in the tank; readers who don't own one are given alternatives where possible. Science Fair requires more advanced knowledge of science terminology and vocabulary; terms such as "vomeronasal organ" might be difficult for some readers to understand, and there is no pronunciation guide. Students will enjoy learning about smell and taste through projects with food odors, socks, jelly beans, and more. Libraries serving populations that are interested in science fairs will find these two books worth purchasing.-Michael McCullough, Byron-Bergen Middle School, Bergen, NY Copyright 2002 Cahners Business Information.
