A-Z STEM Saturday, P is for Pulleys

Through out this month of January, I will be participating in a collaborative series with 53 other bloggers organized by Little Bins for Little Hands to bring you the A-Z of STEM subjects. While this A-Z STEM series is happening, we also still have our weekly STEM Saturday linky party! This week we’ll be talking about pulleys.

A-Z STEM Saturday - P is for Pulleys (1)

“A pulley is a wheel on an axle or shaft that is designed to support movement and change of direction of a cable or belt along its circumference. Pulleys are used in a variety of ways to lift loads, apply forces, and to transmit power.” (site)

Pulleys are one of the six simple machines, the other five being lever, wheel and axle, inclined plane, wedge, and screw.

We have worked with a crude version of a pulley many times in our play. In our outdoor learning space, we have a bucket and rope contraption which is essentially just a pulley. It has proven to be very popular with the children.

All you need to create a simple pulley for play is a container (bucket, basket, cup), a belt (rope, yarn, string), and a stationary object to act as a wheel or axle (tree branch, door knob, tension rod in a door frame).

Children pull at the belt, and up the container goes. They experiment with letting go to see how fast it falls. Filling the container with objects to see how difficult (or not so difficult) it becomes to lift.
They gain a base STEM knowledge through this simple hands-on experimentation, without any direction from adults what-so-ever.
