Using inexpensive materials (e.g., tape, paper clips), students build simple machines-such as levers, pulleys, spring scales, gears, wheels and axles, windmills, and wedges-that demonstrate how things work. Activities have easy-to-locate materials lists, time requirements, and step-by-step directions (usually illustrated) on presentation. Ideas for bulletin boards, learning centers, and computer-assisted instruction are an added bonus.
