Pulleys

Seventeen pages of material leave you well-prepared to carry out this lesson on levers and pulleys. Photos and diagrams make the instructions clear; resource links provide additional information. The missing aspects of this teacher's...

Stretch, twitch, and jerk with a simple machines science activity. Three distinct exercises to explore pulleys, levers, gears, and how they are used daily in our world.

Students interpret drawings and reproduce them in a CAD format.  In this design lesson students complete an assembly drawing of a pulley system.

An aerospace engineer and some preteens have a virtual conversation about pulleys. This modern video uses the raising and lowering of the Space Shuttle to show that pulleys can be used to lift very large weights. Show this video to your...

Introduce your class to to the remaining three simple machines-- the lever, pulley, and the wheel-and-axle with a plan that includes the three different types of levers in the discussion of levers. The lesson continues with the...

Students work in small groups and construct a simple machine known as a pulley.

Determine the meaning of the ideal and actual mechanical advantage of a pulley system. As learners complete the simulated experiment, they make a connection to the mechanical advantage of a pulley system and the number of fixed and...

Which pulley system will give us a whale of a good time? Teams compare the theoretical and actual mechanical advantages of different pulley systems. They then form a recommendation for how to move a whale from an aquarium back to the ocean.

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...

Here is a tri-faceted resource that has a slide show, a quiz, and a vocabulary list that you can use to teach simple machines. Six machines are introduced: wheels and axles, planes, levers, pulleys, wedges, and screws. Slides contain...
