- How has the surface of our planet changed over time?
- What clues are provided to show that the surface of our planet has changed?
Materials (per 2-3 students): I make these ahead of time to save time in class and I can reuse them for each class.
- Foam Board
- Glue stick
- Disposable scalpel or sharp craft knife
- USGS landmasses (Pangaea activity PDF)
- Blue construction paper
- Ziptop bag
- Print out and glue landmasses to a piece of foam board
- Carefully cut out each land mass and fossil key
- Place into zip-top bag
- Have students place the landmasses into their current geographic positions on top of the blue construction paper.
- What do they notice about the landmasses? Discuss.
- Ask students: “Do you think you can make one large landmass using the clues provided?”
- After a few minutes, check on their progress, what did they do first? What was giving them difficultly? Encourage students to try alternate possibilities.
- Discuss findings, what possibilities did they come up with?
- Ask students how the landmasses moved to their current position- accept all possibilities.
- Ask students: “Are the landmasses are still moving?”
- Show “Animated Life: Pangea” by the NYTimes
- Have students try to create Pangea again.
The Pangaea Pop-Up video is a great video to show also:
