Day 2

Visual Representation and Properties of Water

  • Have students colour in correct proportions of t water, glacier ice and fresh water on their pie graph.   (5 min)
  • Ask students to reflect on their initial reaction to this data. (15 min)
  • Ask students to share their reflections as a class. (10 min)

 

  • Conclude class with these Three Water Puzzling Questions:  (20 min)

What do you think would happen if ice did not float?
What would happen to the fish and plants in the water?
How does the ice on top of the lake help the fish and plants that live underneath?

Answer: 
If ice did not float, lakes would freeze from the bottom up.  The plants and the fish would also freeze.  Most of them would die.  The ice on the top keeps the water underneath protected from the cold.  It is like a blanket that keeps the water at a safe temperature for living things in the lake.
