Grade Two Science: Sink or Float
Abbe Roth

Grade Two students have been experimenting around the factors that affect buoyancy. Over the past couple of weeks, they have:

  • Experimented with objects of the same shape and material but of different sizes, in order to discover whether size is a factor that affects buoyancy
  • Examined the effect of bubbles on the buoyancy of an object submerged in carbonated water
  • Shaped pieces of clay to discover if the shape of a material affects the objects buoyancy
  • Students determined the circumstances under which some metal objects can float

This activity will lead into their study of the Mayflower.
