Gr 1-3-An excellent source of basic information and activities. Double-page topic treatments address what magnetism is, how and why it works, attraction and repulsion, the earth's magnetic field, compasses, and electromagnets. Of the projects included, some can be done alone, while others require adult supervision. Clearly worded explanations of why the demonstrations or projects work and some ideas for further exploration are also given. Full-color photos are helpful and cartoon characters add to the visual appeal. The last page includes seven magnet facts and a short glossary. Youngsters will be drawn to this attractive title.-Sandra Welzenbach, Memorial High School, San Antonio, TX
Each double-page spread in this colorful book in the Science for Fun series presents one simple science project involving magnetism. Although the author talks around the self-posed question "What Is a Magnet?" without defining or explaining the word, he ends each project with a section called "Why It Works," which contributes to a working knowledge of the subject. Even primary-grade children could make and play around with many of the projects, with help from a parent or teacher. Most of the materials are readily available supplies such as magnets, cardboard, tape, screws, nails, and compasses. Though crowd"ed with photographs and diagrams, the pages look colorful and the drawings clarify the directions. Good supplemental material."
