Student Exploration: Building Pangaea
Vocabulary: continental drift, fossil, glacier, ice age, landmass,
Pangaea, supercontinent
Prior Knowledge Questions (Do these BEFORE using the
Gizmo.)
1. Antarctica is a frozen land, so cold and icy that no trees can
grow there. Yet scientists have discovered fossils (remains
preserved in rock) of ancient trees in Antarctica.
What do you think this means?
________________________________________________
_____________________________________________________
13. ____________________
2. The Himalayas in central Asia are the tallest mountains in the
world. But fossils of seashells can be found high in these
mountains, far from any ocean.
How do you think they got there?
______________________________________________
_____________________________________________________
____________________
Gizmo Warm-up
1. The Gizmo allows you to drag and rotate all the major
landmasses on Earth.
· To drag a landmass, grab it in the middle.
· To rotate a landmass, grab it near the edge.
· Learn the names by opening the Tools menu and dragging the
Help icon over the landmasses.
· Mark where you live. Drag an arrow from the purple bar at left
to your location.
14. 2. Test your geography skills. Drag and rotate landmasses
randomly until you make a big mess. Then try to move them
back to their original positions.
When you have made the best map you can, click the Tools icon
in the upper right corner, select Screen shot, and copy the image
into a blank document. Label the image “Map 1.”
3. Click Reset. Compare your map to the real one. How well did
you do? _________________
_____________________________________________________
____________________
Activity A:
Solving the puzzle
Get the Gizmo ready:
· If necessary, click Reset.
· Check that the Evidence shown is None.
Introduction: In 1915, a German scientist named Alfred
Wegener (VAY-guh-ner) proposed the theory of continental
15. drift. According to this theory, the landmasses once were joined
into a supercontinent called Pangaea. The landmasses then
slowly drifted to their current positions.
Question: What did Pangaea look like?
1. Observe: Drag South America close to Africa. Look at their
coastlines. What do you notice?
_____________________________________________________
____________________
2. Explore: Try to fit all the landmasses together like a puzzle.
· As much as possible, avoid overlapping landmasses.
· When you are satisfied, take a screenshot and paste it into
your document. Label this map “Map 2: Fit of the continents.”
3. Analyze: Look at your map of Pangaea.
A. How well do the continents fit together?
___________________________________
B. Is it a perfect fit? Explain.
16. ______________________________________________
C. Think about how the landmasses got from where they were to
where they are today. Does it seem realistic that the landmasses
could have moved like this? Explain.
_____________________________________________________
______________
_____________________________________________________
______________
4. Compare: If possible, present your map of Pangaea to your
classmates and teacher. Look at other maps, and talk about each
one.
A. Are the maps very similar or very different?
________________________________
B. If Alfred Wegener showed you a map like this but did not
have any other evidence, would you have believed his theory
that the continents had moved? Explain.
_____________________________________________________
18. _____________________________________________________
______________
B. Lystrosaurus probably couldn’t swim very far. How might
the locations of Lystrosaurus fossils be seen as evidence that
the continents were once together?
_____________________________________________________
______________
2. Explore: Use the fossil evidence to help you make a new map
of Pangaea. When the map is done, paste a screenshot into your
document. Label this map “Map 3: Fossil evidence.”
How well do the landmasses fit together this time?
_________________________________
3. Revise: Now under Evidence choose Rocks. The purple areas
are mountains that formed when landmasses collided 450
million years ago. The orange areas show rocks that formed
about 2 billion years ago.
Adjust your map using this evidence, and then paste a
19. screenshot of this map into your document. Label this map
“Map 4: Rock evidence.”
4. Compare: If possible, compare your map to those of your
classmates.
A. How similar are the maps?
_____________________________________________
B. If Wegener showed you this evidence, would you have
believed his theory? Explain.

5. Extend your thinking: Click Reset and watch India closely.
The Himalayan Mountains are found on the border of India and
Eurasia. How do you think these mountains were formed?
_____________________________________________________

20. _____________________________________________________
____________________
Activity C:
Ancient ice sheets
Get the Gizmo ready:
· Click Reset.
· Under Evidence choose Glaciers.
Introduction: Glaciers are large, slow-moving sheets of ice.
During ice ages, glaciers formed at the North and South Poles
and spread out to cover large areas.
Question: What does evidence of glaciers tell us about Pangaea?
1. Observe: The white areas are places that show evidence of a
massiveice sheet that existed around 250 million years ago.
A. Which landmasses show evidence of ancient glaciers?
_______________________
_____________________________________________________
______________
21. B. Would you expect to find large glaciers on all of these
landmasses today? Explain.
_____________________________________________________
______________
_____________________________________________________
______________
2. Explore: Drag the landmasses together to form a map of
Pangaea. Try to line up the white areas on each continent. You
can use the fossil and rock evidence as well if you like. Paste a
screenshot of this map into your document, labeled “Map 5:
Glacial evidence.”
3. Analyze: Choose Glaciers (if necessary) and look at the white
regions. Does this pattern make more sense now? Explain.
______________________________________________
_____________________________________________________
____________________
22. 4. Extend your thinking: As glaciers moved away from the
poles, rocks stuck to the bottom of the ice were dragged over
the ground. This left scrapes and scratches on rock outcrops that
can still be seen today. The scratches show which direction the
glaciers moved.
A. Look at the arrows that show the direction of glacial
scratches. What is the pattern?
_____________________________________________________
______________
B. Which landmass do you think was located over the South
Pole in the time of Pangaea? Why? Discuss your answer with
your teacher and classmates.
