Efficiency of a Pulley System

Students investigate a pulley system in the lab. In this pulley system lesson plan, students build a pulley system using weights, strings and wheels. They calculate the work output, work input and efficiency of the system. They also find the ideal mechanical advantage and the actual mechanical advantage of the system. Students answer 6 post lab questions about the system they built and how friction effects the work.

When I am trying to find an alternative lesson from my norm, I try Lesson Planet, and always find a lesson that I can use. Sometimes a different perspective from a colleague can be that "point" that will work for that concept. I really feel that Lesson Planet is very well organized and easy to use. Thank you so much Lesson Planet for your help in my classroom.
