Gather various items – mirrors, cups with water, objects like pencils, flashlight, fabric and colored paper.

Question and Wonder:

  • Why does the color of sunlight change when it shines through your curtains?
  • I wonder what the light would look like if you put a scarf over your eyes.
  • How do sunglasses change how you see?
  • What are other ways you can change how you see things?

Using the materials you have gathered, play with the flashlight.

Imagine and Design:

  •  How may you see the items in different ways using these materials?
  • How does the light change as you shine it through the water? The fabric?
  • What if you put things in the water? What happens?
  • What does the pencil look like if it’s in the glass of water?
  •  What did you notice? What if you place the colored paper or fabric over your flashlight and then shine it at things?
  • Try bouncing the light off the mirror. What happened?
  • How else can you use the mirror?

Test and Discuss:

  • What have you learned form your observations?
  • How can you make predictions of how light will act based on what you observed?
  • Describe to someone else what you saw and how you think we see.
