Materials:

  • Water Displacement – Volume Lab Handout (pdf)
  • 1 container of water per group
  • 2 graduated cylinders per group of 4 students
  • 1 plastic tray per group
  • 1 plastic spoon per group
    • this is used to stop item from falling into the container and to fish out items if needed
  • paper towels or cloth towels
  • green or blue food coloring – a few drops per 500 mL
    • adding food coloring helps the students to make accurate readings since it easier to see the water, plus it is fun to work with :)
    • I don’t like to use red or yellow, they tend to stain more than the blue and green food coloring
  • an assortment of small objects such as pennies, rubber stoppers, marbles, pebbles, etc…
