Things That Float and Things That Don't

For this activity students are challenged to make the same object both sink and float, encouraging them to think about why objects either sink or float, and then how it is possible that the same object can be made to both sink and float.This resource has two differentiated results sheets and questions: 1 - A simple question about the properties of items that sunk. 2 - A question to encourage critical thinking about how it is possible the same object can be made to both sink and float.
