Grades: 3-5
Investigate and experiment with 8 functioning lever and pulley models designed to demonstrate science and technology concepts related to three classes of levers and fixed, movable, combination, and block and tackle pulley systems.

Key Concepts Identify all three classes of lever and test them to determine how they operate Identify key parts of levers: effort arm, resistance arm and fulcrum Identify different types of pulley systems and test them to determine how they operate Identify key parts of pulley systems Discuss how pulleys change the direction and/or amount of force applied to do work

Build 8 different real-world models, one at a time. Models demonstrate 1st, 2nd and 3rd class levers along with fixed, moveable, combination and block and tackle pulley systems. Set includes building instructions with real-life photo and key facts and comes packaged in a strong, stackable, plastic storage case with movable dividers and locking lid. Designed for groups of 2-3 students to build and investigate as a team.
