Question and Wonder:

  • Why does the color of sunlight change when it shines through our curtains?
  • What are other ways I can change how I see things?

Imagine and Design:

Gather various items – mirrors, cups with water, objects like pencils, flashlight, fabric and colored paper. How may I see my items in different ways using these materials?

Test and Discuss:

  • What does the pencil look like if it’s in a glass of water?
  • Without the pencil, shine the flashlight through the cup of water. What did you notice? What if you place the colored paper or fabric over your flashlight first?
  • Describe to someone else what you saw and how you think we see.
