Levers, Pulleys and Gears
This science scheme of work for Key Stage Two gets the children to research, test and illustrate how to use levers, pulleys and gears to change the direction and strength of forces. The class can record diagrams, make models and write explanations about how to use a mechanical advantage for different functions.
Research, test and illustrate how to use different types of levers, pulleys and gears to change the direction and strength of a range of forces
Lesson One : Using Levers
Identify, describe and record how to use different types and classes of levers to move a specific load around a matching pivot point
Lesson Two : Pulleys
Explore, describe and model how to use a system of pulleys as a mechanical device to move a specific type of load in different ways
Lesson Three : Gears
Identify, describe and record how a system of gears can be used to direct, transfer and change a range of different movements
Lesson Four : Gadget Inventions
Practise planning and producing a class presentation to demonstrate how to use mechanical advantages for levers, pulleys or gears to solve a problem
Levers, Pulleys and Gears Assessment
Assess abilities in researching, testing and illustrating how to use different types of levers, pulleys and gears to change the direction and strength of a range of forces
