Topic B: Wheels and Levers
General Learner Expectations
4-6 Demonstrate a practical understanding of wheels, gears and levers by constructing devices in which energy is transferred to produce motion. Students learn about basic components of simple machines: how they are assembled, how they operate, how they are used. Students explore different techniqques that can be used to transfer motion from one compenent to another, using simple connectors and carious levers, gears, pulleys and band driven systems. As they work with these componets, they learn the functions that each can perform, including sample applications and ways that they can be used in a larger system. As part of their studies, they examine how these simple machines are used to change the speed or force of movement. |
