Will it float, and will it stay upright? Archimedes in three sessions.
- Session 1: Things float when the water they push aside weighs as much as they do (Level 1, 60 min)
- Session 2: The buoyant force, barge loads and balloon lift (Level 2, 75 min)
- Session 3: Does it stay upright? Metacentric height and the righting arm (Level 3, 90 min)
