Additional Prerequisites

• Teachers may want to introduce students to the topics of ice cores and climate change in a group setting before they use this self-paced resource.
• The graphics and layout of the resource look a little dated, but the interface is easy to navigate.

Differentiation

• Teachers could create comprehension questions in a Google form or on paper for students to complete as they work through the self-paced text.
• Before assigning this lesson, ask students to write down their responses to the following questions:
  • How do scientists know what Earth's climate was like in the past?
  • What could ancient ice tell us about the climate?
  • Can scientists access ancient ice? How?

• Consider pairing this resource with this interesting video tour of the National Ice Core Lab.
