Challanges
You have to lift up a load from the base to a certain height using the idea of an elevator.
How tall an elevator can you design and make it work?
Challenge them to adjust the pulley system to see how quickly they can lift a certain weight.
You can provide them with different-shaped objects and let them experiment balancing the load in the elevator.
Can multiple pulleys be used in this, and how can it make the differences?
Questions to be asked
How do the differences in weight change the system of pulley and its speed?
If more weights are added, what changes need to be made?
What differences can be seen when only one bottle cap is moved and when both the caps are moved?
What should be done to move the elevator faster?
