Resources Required

  • Student Worksheets – one copy per student
  • Device capable of presenting a video to the class
  • Demonstration Equipment:
    • Various items with sugar (e.g., lemonade, milk, water, apple juice)
    • cups (to match the number of items)
    • sugar
    • teaspoons
    • sticky notes
    • zip lock bags
    • marker pen
    • an orange (cut in half)
    • paper plate worksheet or paper plates

Prior preparations: Organise eight sticky notes. Leave four of these blank, they will be filled in when the student predicts how many teaspoons of sugar are in the item. Write on the remaining four sticky notes: water = 0 teaspoons, juice = 7½ teaspoons, soft drink = 7½ – 16 teaspoons (this number varies greatly!), milk = 1 teaspoon. 

Set up a demonstration area with the items containing sugar. Place an empty cup with each of the items. Put the sticky notes on the table as well (make sure the sticky notes that are written on are kept hidden). Place a spoon and zip lock bags, marker pen and orange (cut in half) on the table as well.
