Title: 💡 Pirate Rigging Lab: How Do Pulleys Help Pirates Lift Treasure?

Summary:
Students explore how pulleys affect lifting force and rope distance. They test no pulley, fixed, movable, and compound systems, measure force and rope pulled, and calculate work (W = F × d). Results show fixed pulleys change direction only, movable pulleys reduce force but increase rope distance, and compound pulleys reduce force most. Total work stays roughly constant, demonstrating the force–distance tradeoff. The teacher key provides expected trends, example data, and analysis guidance.
