Using 3-D animation, high-quality video and audio, and a touch of humor, this CD-ROM examines how machines are used to make work easier. This valuable instructional tool can be used as a supplement to the Simple Machines and Work video series, or as a stand-alone lesson on simple machines. Each simple machine (inclined plane, wedge, screw, lever, wheel and axle, pulley) is defined, and a brief history of the machine is provided. Users can access examples of the different kinds of machines and learn how to calculate the mechanical advantage of each. A quiz section covers important information and allows users to evaluate their retention. This CD-ROM provides a fun and interesting look at simple machines. A Cambridge Educational Production.
