[Simple Machines guide]

Simple Machines includes the CPO Science Ropes and Pulleys, Gears, and Levers. In the Ropes and Pulleys investigations, your class will explore the principles of force and work as they discover how to arrange the strings for increased mechanical advantage. Ropes and pulleys are the ideal hands-on tools to enable you to teach the concepts of work and energy to your students. In the Gears investigations, important ideas such as ratios, angles, and the geometry of the circle become "real" to your students. Through the Levers investigations, students easily derive the relationship between force and distance on a lever. They also explore the concepts of work and torque. In addition, students explore how engineers design, test, and refine machines.
