Block and Tackle
Can you easily lift more than your own weight? With a pulley system, almost anyone can manage this challenge. Scholars adjust the mechanical advantage (number of pulleys), weight of object being lifted, and the length of rope pulled. The...

Pulleys
Students determine how to tell the difference between a simple system and a complex pulley system. Using pulleys, students build simple pulley systems to demonstrate the mechanical advantages of pulleys.

Is a Pulley a Special Kind of Lever?
Fifth graders use information from their text to read and discuss pulleys and levers. They examine a top sketch of the arrangement of a fixed pulley. Working in groups, 5th graders perform experiments to test the effect of using a pulley...

A Simple Block and Tackle Pulley Demonstration
Students investigate the scientific concept of mechanical advantage. They construct their own system with the use of a simple broomstick. Then the demonstration is done to show how the mechanical advantage is used to move a load.

Investigating Pulleys
Students investigate pulleys and see how they have a mechanical advantage in lifting heavy loads. In this pulley activity students make a hypothesis, complete and experiment then complete a worksheet.
Curated OER
Lift and Pull
Middle schoolers examine the mechanical advantage of pulleys. In this pulleys lesson students are given a challenge to help save a whale by setting up different pulleys systems to move it.
