Part two sees students develop their understanding of levers and pulleys and relates this to how cranes launch and recover submersibles. Students will continue to develop their crane, this time adding a lever or pulley system which will raise and lower their submarine model. Students will reflect on their build, evaluate the effectiveness of their cranes and make suggestions for improvements. Finally, students will demonstrate their learning by creating a poster which describes and explains how cranes work to launch and recover submersibles, concluding the Submarine STEM unit.
