Book 38: Understanding Buoyancy: Why Objects Float or Sink
Synopsis
Understanding Buoyancy focuses on the popular topic of floating and sinking. The medium of water has been chosen because it is relevant to children's everyday experiences and observations. Most children have some understanding of how they themselves, and everyday objects, float or sink in water.
At this level, the topic can be extended to floating and sinking in other media (for example, in air and in other fluids) as appropriate to the children's experience and level of understanding.
