Do I have a
story to tell!
EVERY ROCK HAS A STORY
NAME _____________
DATE _____ HOUR ___
Most rocks were created millions of years ago and there were no “witnesses” to their
formation. This makes careful observations of the rock very important.
Visit each of the stations on the lab tables in any order and make careful observations.
From your observations, derive a hypothesis about how the rock formed. The final step is
to explain how to test your hypothesis.
Station 1: Round rock
Observations:
Hypothesis of formation (story of the rock):
How you would test your hypothesis:
Station 2: Playa tracks
Observations:
Hypothesis of formation of the tracks:
How you would test your hypothesis:
Station 3: Green striped rock
Observations:
Hypothesis of formation (story of the rock):
How you would test your hypothesis:
Station 4: Geode
Obserations:
Hypothesis of formation:
How would you test your hypothesis:
Station 5: Triangle Rock
Observations:
Hypothesis of formation:
How you would test your hypothesis:
Station 6: curved rock
Observations:
Hypothesis of formation (story of the rock):
How you would test your hypothesis:
Station 7: holey rock
Observations:
Hypothesis of formation (story of the rock):
How you would test your hypothesis?
Conclusion questions
1. In general, what problems did you encounter with this activity?
2. A problem when creating hypotheses in geology is that it is difficult to recreate
things that existed in the past. List as many factors as you can that have changed
over time that could influence geology.
