Curated OER
Teaching About Simple Machines
Students identify six different simple machines. They investigate the difference between the ideal and actual mechanical advantage. Students calculate the actual mechanical advantage for several simple machines.

Tools and Equipment (Part 1)
Looking for the best inclined plane for the job? Groups calculate the theoretical mechanical advantage for four different inclined planes. They determine the actual mechanical advantage by measuring the amount of force needed for the...

Simple Machines, Engines and the Environment
Pupils examine and describe the six main simple machines. In groups, they work with an inclined plane to calculate the ideal and actual mechanical advantages of the plane. Using their results, they must determine the efficiency of the...
