ESR’s exhibit focuses on the concept of density and the ocean by providing several hands-on activities which explore the properties of density. Participants get to:

  • Compare objects of the same volume but different weight.
  • Play the “Sink or Float” guessing game: compares the density of solid objects to water using an aquarium.
  • Observe the different densities of liquids in a density tower.
  • Experiment with cold/salty water and warm/fresh water using beakers, colored water and pipettes to see the density differences.
  • Discuss how density is important in the ocean.
