STEM: Pulling Penny the Polar Bear

The students completed our most complex STEM challenge of the year when we began researching the weight of polar bears. The challenge continued with students viewing selected videos on pulley systems, followed by project designs to build a pulley driven tool which would elevate a polar bear to the top of the mountain.  All groups were very successful with the challenge, despite the limited amount of duct tape that was available in the 21CLL.

Below are a few action photos of students working on their designed creations.

This pulley was great engineering, with the full loop pulley being used.

This group decided to use a ramp in their system.

The team problem solved a setback with the varying heights of their tubes.

More from the full loop pulley group.

This was a very successful group which used a system which included a balanced seat for Penny.

This group persevered by building, video taping, and then rebuilding for another run when the video was accidentally deleted. Always learning. Always growing!
