Designed to help pupils aged 8-13 learn about the science of zoology, this text outlines complete, hands-on science projects. All experiments are designed to conform to conventional science fair methodology. Each chapter is categorized by topic and contains an introduction explaining its background and application, providing teachers and pupils with ideas and instruction. Topics covered include genetics and heredity, cell division and differentiation, learning and memory, animal behaviour, evolution theory, immune response and behaviour, biological clocks and communications. The experiments can be performed in the classroom or assigned to pupils for independent study, and each offers suggestions that challenge the pupil to think more widely about the subject.

Grade 4-7-This useful title will work best in a classroom setting with adult supervision. Cautionary icons appear throughout to call attention to potentially hazardous situations, and Dashefsky provides warnings to prevent harm to any of the creatures observed in the experiments. The introduction explains how to organize projects and gives brief background material about the animal kingdom and the classification system. Grouped into nine broad areas-behavior, the senses, growth, etc. -each project includes an overview, a list of needed materials, clearly written instructions, hints on drawing conclusions, and suggestions for further study. Black-and-white drawings and charts help to clarify procedures. Many of the activities are simple, requiring no special apparatus; some that are more complex call for laboratory equipment or animals that may not be readily accessible. Projects are well organized and give enough information and encouragement to enable students to carry out successful investigations. Mary Dykstra's The Amateur Zoologist (Watts, 1994) is more challenging and could be a suitable follow-up.

Gr. 8-12. Dashefsky takes no chances: he recommends adult supervision for all 49 projects he includes in this book and also uses an icon code to identify which require "closer supervision for younger students." Even so, he addresses the students themselves, who will find a fascinating array of projects, quite varied in difficulty, to choose from. The experiments, none of which is extremely complicated, run the gamut from investigating antigens in human blood to plotting the respiration rates of goldfish. Dashefsky presents them clearly, with an overview of the experiment preceding a list of materials, step-by-step instructions, and follow-up questions designed to make students think about what they've observed. The author's discussion of the scientific method and his ongoing emphasis on accurate recording of data will be a great help to student researchers. Because the projects frequently require special equipment or specimens (for example, a centrifuge or fruit flies), Dashefsky includes a listing of scientific supply houses. Occasional black-and-white sketches help clarify the procedures. Stephanie Zvirin
