Week 9: Geologic Time

The big question this week was: How do we think about geologic time? 

What did you do in lab today?

In lab, we talked about geologic time. We put sticky notes on a timeline to show how incredibly close in time each geological and biological event was, compared to the billions of years after the Big Bang. Each group chose 5 interesting events to put on the timeline. 

What did you learn in Thursday's discussion? 

We took the Space quiz on Thursday.

What did you learn? 

• Plate tectonics caused the movement of land masses that formed differently-shaped continents throughout geologic history. 
• The Continental Drift theory didn't explain how or why the continents moved around, just that they likely did. The plate tectonics theory explains how and why the continents moved and still move. 

What was most helpful? 

• The drawn out cycle of cooling and more cooling. It helped me understand the process and align it with the visualization of the process that I have in my head. 

What do you need more information on? 

• I'm excited to learn more about how plate tectonics works! I remember some stuff from previous geology classes, but I'm excited to learn how to teach it to kids.
