In this physics activity, learners will explore buoyancy. They will use a variety of objects to practice their prediction skills (what will and won't float) and discover why some things are more buoyant than others. In the "What's Going On?" section, there is a tie-in to the Titanic and why large ships can float. This was originally designed as part of a Family Workshop for all members of the family to work together; however, it can easily be used in other ways.
