- Students need to recognize that this video discusses natural climate changes over the course of tens of thousands of years.
Differentiation
- The video pairs well with this NASA article about Milankovitch cycles.
- Teachers could pause the video at certain moments in order to reinforce key concepts.
- This video could supplement a lesson on the exact mechanics of Milankovitch cycles and why these cycles cannot explain Earth's current warming.
- Teachers could create a formative assessment based on the main concepts of this video.
