Grades K-8. One pulley can be used to change the direction of the force applied by a cord. A small force on the cord can be use to lift a large weight. Experimenting with the device shows why lifting the block by a short distance requires that the cord be pulled a long distance. Excellent for small groups or individual study. Includes a detailed activity guide which details the history of the model, practical applications, and classroom experiments. Overall dimensions: 13 in. x 4 in. x 6-1/2 in.
