Blog Post Week 9

1. The big question addressed in lab, and a description of what you did.

The big question that we addressed in lab was what are the significant events in the history of the earth.We used earthviewer to explore and discover different significant events on our own and with our groups to learn about the history of the earth. One of the interesting things that I found was how late on the timeline humans appeared compared to all of the other things. 

2. A description of what you learned in Thursday's lecture.

This week we had a quiz in Thursday's lecture. 

3. Answer questions about the weekly textbook reading:

1. What did you learn?

One thing that I learned from this chapter was about the snowball earth which I have never heard of before. The snowball earth is where the earth was almost all the way filled with ice and we know this because of sedimentary rocks. It was caused by a positive feedback loop which is where one specific change is going to affect the next change into a specific cycle that encourages the initial change. It creates a cycle of ice growth, increasing albedo, less insolation absorbed, cooling, and repeat. 

2. What was most helpful?

One of the things that I thought was most helpful was including the specific K-6 standard that relates to what I was reading. This was helpful because it's important for me to be able to correlate specific information with the specific standards I am going to be teaching in the classroom. 

3. What do you need more information on?

One thing that I need more information on is continental drift. I had learned about the basic concepts and ideas about what continental drift is. However at the end of the chapter it explains how some of his ideas were not accurate, such as how the continents separated, which was explained by plate tectonics. However, I would like more information on the different things that were proved false with this theory and more information about plate tectonics. 

4. What questions/concerns/comments do you have?

I was super interested while reading about the snowball earth because of all of the other theories and major events in the text I have heard about before. I have learned about pangea and continental drift in the past, but don’t remember ever learning about or hearing about the snowball earth.
