Submarine STEM KS2: How do you launch a submarine with strong structures?

This is the fifth in a six lesson unit, Submarine STEM KS2. We reccomend that you take students on the journey of levers using both lesson five and six. Lesson five develops students understanding of strong structures and investigates how cranes work. Students work together to design and construct a crane using a variety of materials. They will also construct a model submersible to launch and recover once their crane is complete. This lesson is from the Submarine STEM 7-11 unit. You can access the unit here:

The unit enables students to explore materials, forces, and living things while working scientifically. The unit is based on real life submersible exploration of the XL Caitlin Deep Ocean Survey off Bermuda, the Sargasso Sea. To experience the full impact of this scheme of work it can be taught in advance of our annual Submarine Live event. Live lessons can be booked for free here:
