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.
Opening: Wegener Song
Work Session:1. PP Presentation – Fossils2. Examine fossil specimens
Closing: Smart Board Activity - Fossils
How fossils form
Wegener used fossils as part of his evidence for
Continental Drift.
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.
(Greek for "dog jaw")
Wegener’s Fossils
Could this “little guy” have swum across the Atlantic Ocean? Walked across a land bridge?
Cynognathus
Mesosaurus means “middle lizard”Fresh water reptile, swampy areas
The Principle of Superposition• Younger rocks on top and
Older rocks on bottom!
C Youngest
B
A Oldest
Let’s Talk about the Disturbances!
Relative DatingAllows a scientist to compare the age of a fossil with other fossils around it.
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.
Closing:
• As a group, examine the fossils.• Can you categorize them? (Put them in some sort of order?)

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.
