Sprott (physics, U. of Wisconsin-Madison presents 85-plus demonstrations suitable for attracting the attention of students, after which explanations of the physical phenomena will sink in all the better; the reverse approach, that is, demonstrations designed to illustrate particular principles, he feels are more appropriate for the lab and not as effective for large groups. The demonstrations are arranged in sections on motion, heat, sound, electricity, magnetism, and light. Along with description of materials, procedure, concepts for discussion, and possible hazards, each includes illustrative photos and references. Two included DVDs supplement the text.
