SECONDARY: The Cartesian Diver Investigation
The classic Cartesian Diver physics experiment gets re-worked as a magic trick, to help a Year 7 class explore pressure and density, in this fun idea for transforming classroom practice. Physics teacher Alan Haigh carries out the Cartesian Diver experiment about pressure and density in front of his Key Stage 3 class but disguises it as magic trick, complete with wand. The pupils construct their own theories as to how the diver is moving, such as magnetism and static electricity. Alan then provides them with a range of laboratory equipment to test their theories. Alan, a science teacher at Woodkirk High School, first used this lesson idea with his tutorial group but now uses it across year groups.
You can use this video in three ways. If you like it and it fits your pupils then why not try the actual lesson: there is a lesson plan and other materials below. You could adapt it for your subject and age group or you might find it jogs you into trying something entirely different.
