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...

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...

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.

Simplify students' lives with this physical science note-taking guide. From inclined planes to moveable pulleys, this resource supports young scientists with defining each type of simple machine while identifying their mechanical...

Teach young engineers that all machines, no matter how complicated or complex, are made up of just six simple devices with this hands-on physical science instructional activity. Using the included templates, students first create paper...

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...

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 instructional activity continues...

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.

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...

Show your students how to make their work easier. The first lesson in a series of 10 introduces the class to work and the way simple machines can be make work easier. The simple machines scholars can find in everyday items are inclined...
