Suggestions to teachers:
1. Suggested questions for students when viewing the clip:

a. What is a pulley system designed to accomplish?

b. What are the necessary components of a pulley system?

2. A good investigation for students to partake is to design their own pulley system to lift a specified object. Students need to draw a force diagram and provide calculations. They will be tested to see if their pulley system actually works.
