The screw, another of the simple machines, 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.

Includes a detailed activity guide which details the history of the model, practical applications, and classroom experiments. Measures 19 1/2L x 10W x 4H".
