Submarine STEM KS2: How do you choose materials for a submarine?

This is the fourth in a six lessons unit, Submarine STEM KS2. This lesson discusses the properties of materials and their use in submersible design. Students will compare a variety of materials for their submersible and justify their choices. An investigation into how salt water affects materials allows pupils to make predictions, write conclusions and conduct a fair test. This lesson is from the Submarine STEM 7-11 unit. You can access the unit here: https://encounteredu.com/teacher-resources/submarine-stem-science-ages-7-11.

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: https://encounteredu.com/live
