Analyze the cartoon. (What does it represent ?)

In this lesson, students will analyze the connections between fossils and plate tectonics, focusing on how fossils provide evidence for continental drift. We'll examine fossil specimens like Cynognathus and Mesosaurus, discuss their characteristics, and explore how they relate to the movement of Earth's plates. The concepts of relative dating and the Principle of Superposition will also be covered, allowing students to classify fossils and understand their ages in geological contexts. Join us in uncovering the past and the dynamic nature of our planet!

Presentation Transcript

  1. Warm – up Monday, December 3 Analyze the cartoon. (What does it represent?)

  2. MYP Unit Question: How does land change? Area of Interaction: Environment Learner Profile: Thinker Standard: Investigate the scientific process of how the Earth's surface is made. Learning Target: Today I’m learning about fossils because their existence helped proved the Theory of Plate Tectonics.

  3. Opening: Wegener Song Work Session: PP Presentation – Fossils Examine fossil specimens Closing: Smart Board Activity - Fossils

  4. How fossils form

  5. Wegener used fossils as part of his evidence for Continental Drift.

  6. Wegener’s Fossils (Greek for "dog jaw") Cynognathus was approximately as large as a modern wolf and, like the wolf, was an active predator. The body of Cynognathus was not massively constructed. The tail was short, and the limbs were tucked well under and close to the body, providing the potential for rapid and efficient locomotion. The skull was long and had openings for the attachment of strong muscles used in opening and closing the jaws.

  7. Could this “little guy” have swum across the Atlantic Ocean? Walked across a land bridge? Cynognathus

  8. Mesosaurusmeans “middle lizard” Fresh water reptile, swampy areas

  9. Glossopteris Fern

  10. The Principle of Superposition • Younger rocks on top and Older rocks on bottom!

  11. Let’s Talk about the Disturbances!

  12. Relative Dating Allows a scientist to compare the age of a fossil with other fossils around it.

  13. Which statement is true about the fossils in the rock layers? a. Fossil 1 is older than Fossil 4. b. Fossil 1 is younger than Fossil 2. c. Fossil 3 is younger than Fossil 5. d. Fossil 3 is the same age as Fossil 5.

  14. Closing: • As a group, examine the fossils. • Can you categorize them? (Put them in some sort of order?)

  15. Warm-Up Monday, December 2 What is the Pacific Ring of Fire and where is it located? The Pacific Ring of Fire is an area in the Pacific Ocean where plate boundaries collide. As a result, there are more earthquakes and volcanoes there than any other place in the world.
