Challanges
Make a stable device that can lift up objects from the base to a certain height. The device should use the concept of a pulley.
Use multiple threads to lift the pulley up and observe how it affects the process compared to the previous one.
You can easily level up the challenge using 2 or more levers to see how it works.
Questions to be asked
What is the difference in using a pulley and bare hands to lift objects?
How can we improve the pulley to make it more efficient and reduce the time required?
If we have to lift up a heavier object with less effort, what changes can be made?
