WHAT WILL WE LEARN?
By the end of the unit your students will understand that:
- Several factors affect the buoyancy of an object.
- Water pushes up on floating and sinking objects with a buoyant force. Because of this, objects appear to weigh less when submerged.
- The amount of liquid an object displaces is directly related to its volume.
- The buoyant force on an object varies with the density of the liquid in which it is submerged.
- Objects that weigh more than an equal volume of water sink; those that weigh less float.
