Float or Sink Answer Key

This worksheet explores buoyancy by having students compare object densities to water and predict whether each will float, sink, or remain suspended. Through applied problem-solving, learners determine density using mass and volume data and interpret how it affects floating behavior. The activity introduces the fraction of an object submerged and connects it to density ratios. Students engage in critical analysis and reasoning about fluid mechanics and material science. This builds practical understanding of real-world phenomena such as floating objects and displacement.
