Explore Buoyancy

Explore when objects float and when will they sink. Learn how buoyancy works with blocks by modifying the properties of the blocks and the fluid.

Some of the sample learning goals can be:
  • Predict whether an object wills sink or float when place in a liquid, given densities of the object and liquid.
  • Apply the definition of density to both liquids and solids
  • Relate the buoyant force on an object to the weight of liquid it displaces
  • Predict the weight of a completely or partially submerged object of known mass and volume
  • Describe the forces that act on a completely or partially submerged object
  • Explain how an object that is more dense than water can be kept afloat by placing it on an object that is less dense than water.
