Theory of Machines

Weeks 6

How basic machines are developed and the theory behind some simple machines eg. levers, ramps, pulleys, gears, wheels. Extension - basic physics worksheets eg. force and distance multipliers, friction.

Problem Solving

Weeks 7-8

Using Lego Technic Activity Centre book, discuss and develop with students a series of tasks to apply the theory eg. construct a paint mixer, electric paintbrush, wind-driven car, cassette winder, rally car.

Theory of Machines

Weeks 9

Discuss with students how engines are developed (steam, electricity) and the operation of the internal combustion engine. Use diagrams to explain the difference between two and four stroke engines. Extension - rotary and diesel motors, latest developments in engines.
