Description
Encourage middle school students to think critically about the geologic time scale with this guided research activity. Students work in groups to read 5 outlines about the 5 major mass extinctions in geologic history. Then, they discuss the similarities and differences between each of the mass extinctions to complete a 3 page worksheet.
Mass extinctions covered:
-
Ordovician-Silurian Extinction
-
Late Devonian Extinction
-
Permian-Triassic Extinction
-
Triassic-Jurassic Extinction
-
Cretaceous-Paleogene Extinction
For each mass extinction, research document includes:
-
When did the extinction occur?
-
What caused the extinction?
-
What were the effects of the extinction?
-
What happened after the extinction?
The 3 page student worksheet asks students questions such as:
-
Do mass extinctions occur at predictable intervals of time?
-
Are extinctions sudden or gradual?
-
In what ways are the 5 mass extinctions you studied similar and different?
Includes suggested answer key.
