4.A Develop an explanation based on preliminary evidence to illustrate that changes over time occur in the existence, diversity, and disappearance of different kinds of penguins throughout history.
What to do
If students don’t have a version of ideas 1-3 above, you could include those statements as three separate claims on a single sheet of paper for students to evaluate and ask them whether they agree or disagree with each claim and why. If students don’t have any of the other possible ideas referenced in the key ideas callout, that is fine. You will look for a version of these ideas when students develop revised explanations in Lesson 6. If students don’t cite any evidence as described in idea 5, remind them to include at least one new line or type of evidence that they would need to either support or refute their ideas for at least one of their explanations.
