Teacher asks students to: - do a research project on Archimedes and his discovery of buoyancy; - read up on ballast and submersibles; - learn how scuba divers manage to stay near the sea floor; - observe how a ball of modeling clay sinks; mould it into a shape that ensures it will float; compete amongst teams to see who can float the most nickels on their clay vessel.
