Description
Thirteen experiments about the six simple machines — the lever, wheel and axle, pulley, inclined plane, wedge and screw — teach kids about basic science. Full-color photographs and step-by-step instructions clearly explain each activity, so that kids can make the most of the machines with minimal help from adults.#Part of the Starting with Science series, Simple Machines encourages children to have fun as they learn basic science and fills a need for primary-level science resources.
