Teacher tip

Bring a real sample of each kind if you can, even a piece of chalk or granite.

How to use it

  • Pass around real rocks and magnifying glasses.
  • Show a jar of layered soil and water that has settled overnight.
  • Start with a two-minute “I notice, I wonder” talk about the picture on the sheet.

Watch for

Kids may think all rocks are the same age. Some are billions of years old.

Talk about it

  • What did you notice that surprised you?
