How do you make a pulley project for fourth grade?

To make a pulley project for fourth grade, you can use a simple setup with a pulley, rope, and a small lightweight object to lift. You can demonstrate how the pulley makes it easier to lift the object by distributing the force needed over multiple ropes. Have the students experiment with different numbers of pulleys and ropes to observe the differences in lifting efficiency. Encourage them to think about real-life applications where pulleys are used, such as in elevators or construction sites.
