Lesson plan

Simple machines

Experiment with levers, wheel and axle, pulleys and inclined planes to understand how force is increased by simple machines
Science content
Physics: Motion and Forces, Newton’s Laws, Gravity (K, 2, 6)
Physics: Simple and complex Machines (5)

Do a selection of the activities, with several simple machines. (Ordered by ones I do most)
See other lesson plans for a focus on Levers or Pulleys.

Summarize that simple machines transform between a smaller force moving over a greater distance and a larger force moving over a smaller distance. They can make jobs easier.

Several simple machines linked together make a complex (or compound machine).
