Grades K-8. An example of a simple machine, which converts a circular motion (the turning of the screw) into a linear motion. It also lets you amplify the force a great deal, since turning the screw only moves the end of the screw a small amount. Excellent for small groups or individual study. Includes a detailed activity guide which details the history of the model, practical applications, and classroom experiments. 7 in. L x 5 in. W x 4 in. H.
