KWL Chart: How Do You Know?

If your students have created KWL charts, have them review the What We Know column. For each item, ask, the following types of questions:

  • How do we know this? (They might respond that they heard it from someone else, read it in a book or on the Internet, saw it on TV, observed it, or "just knew it!")
  • Which sources give you the most confidence that the information is accurate?
  • How can you verify what you think you know?
  • Which do you think is more accurate (reliable): information you get from _____ (a specific outside source) or information you get when you observe something firsthand, review authentic migration data, or conduct an experiment?
