Simple Pulley


Children make simple pulleys using cardboard wheels and strings to lift weights upward, exploring mechanical advantage, force, and basic physics through hands-on play.



Materials :
  • Cardboard
  • Thread
  • Sausage Sticks
  • Masking Tape
  • Double-Sided Tape
  • Bottle Cap
  • Scissors

Challenges:


  1. 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.
  2. Use multiple threads to lift the pulley up and observe how it affects the process compared to the previous one.
  3. You can easily level up the challenge using 2 or more levers to see how it works.

Questions to be asked:


  1. What is the difference in using a pulley and bare hands to lift objects?
  2. How can we improve the pulley to make it more efficient and reduce the time required?
  3. If we have to lift up a heavier object with less effort, what changes can be made?
