Climate Change Lesson

This activity provides a basic lesson for kids about the effects of climate change. It represents the need for ocean temperatures to stay within normal ranges to maintain the health of the coral reef and other vital marine life within the ecosystem.
Climate Change Lesson

You can help this reef recover, and protect other healthy reefs.

Materials you’ll need

  • 1 Box Gelatin (Blue color)
  • 1 Large Measuring Cup
  • 1 Large Bowl
  • 1/2 Cup Cereal in Shape of Pebbles or Sediment
  • Gummy Candy in Shapes of Ocean Creatures
  • Water
  • Optional: Globe or Map to Locate Coral Reefs Around the World


  1. Gently add cereal to the bottom of the clear bowl to make an “ocean floor.”
  2. Mix gelatin according to directions on the package and pour into the bowl. The cereal will float to the top and that’s okay!
  3. Scatter gummy candies around to mimic oceanic movements.
  4. Allow gelatin to set in the refrigerator for several hours.
  5. When firm, add dry cereal to one edge of your new ocean and a few creatures on top.
  6. Reveal the bright colours and textures to show a healthy ocean ecosystem!
