Distributed by The Communication Project, ll-E Paulander Drive, Kitchener, Ont., N2M 5B6. CIP Grades 4-12 Reviewed by Anna I. Holman Volume 15 Number 2 1987 March The Youth Science Foundation, the publisher of Science is... is a national organization responsible for science fairs that annually involve over 400,000 young Canadians. This book is a project of the Foundation. It took four years to develop and has been evaluated for scientific accuracy. It consists of activities varying in complexity from simple puzzles to complex projects. It is divided into three sections: "Quickies," which can be done on the spur of the moment and require few or no materials; "Make Time," activities that can be completed in half an hour to an hour and require some planning and materials; and "One Leads to Another," which consists of related activities in a given subject area. Each activity begins with a one-sentence outline followed by background information and detailed instructions for carrying it out. A symbol, e.g., a bear for living creatures, indicates the general subject areas for each activity. There are ten subject areas. Several features make the book easy to use. At the front are a subject and activity title index, an explanation of how the book is organized, and a "Bulletin Board." The latter consists of a comprehensive list of other sources of information and comments on how the book has been used by a camp director in Alberta, a family in Saskatchewan, and a grandmother in Ontario. The three-ring binder format allows the user to remove only the pages relevant to the activity in hand. As well as increasing portability, it enables several individuals or groups to use the volume simultaneously. Amusing cartoons by Anthony Gower, liberally interspersed throughout the text, contribute to the overall attractiveness of the book. A science professor in this faculty of education noted that the book could be used to introduce topics in science and would complement the new Ontario Ministry of Education guidelines for grades 7 and 8 science. His overall appraisal was: "an excellent resource for school libraries and science teachers." Public libraries should also purchase it, since it can be used by camp groups and families. Anna I.
