Students follow the simple directions to create their own Cartesian Diver. A Cartesian diver is a great way to show buoyancy and density.
Students take their diver and teach the science concepts to 3 other people in the Be-The-Teacher Homework assignment. This reinforces the student's knowledge of the concepts and spreads scientific knowledge. The hand-out for the homework is designed to be cut in half (to save paper). Suggestion - Print it on a bright colored paper to help students not lose it.
