The big question addressed in lab, and a description of what you did. The big question that was addressed in lab was about what are the different layers of earth, and how do plates move. We investigated this by using starbursts to model rock formations. We melted starbursts to demonstrate and see how rock formations are on Earth. We had gone over how there are igneous, sedimentary, and metamorphic rocks. In addition, we went over the answers to the test and about tests.  A description of what you learned in Thursday's lecture. In Thursday lecture we learned about rocks and rock formations. I learned that all rocks started as magma and and then the magma cools. When the magma cools it turns into igneous rocks. The plate boundaries can be classified as divergent, convergent, and transform boundaries.  Answer questions about the weekly textbook reading: What did you learn? One thing that I learned from the textbook reading was about the ring of fire. I have heard this term before...

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.  A description of what you learned in Thursday's lecture. This week we had a quiz in Thursday's lecture.  Answer questions about the weekly textbook reading: 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 t...

  The big question addressed in lab, and a description of what you did. In lab we did presentations about all of the different topics. My group had done the presentation on the origin of the earth. I had learned that black holes can grow by taking matter and small stars are more stable and big stars burn a lot faster. I also learned that there are two different pathways for stars.  A description of what you learned in Thursday's lecture. I learned that light didn’t happen until about 300,000 years after the big bang which I thought was really interesting. I learned that the small star ends up turning into a white dwarf, and the big star ends up exploding and turning into a black hole. I learned that the reason that we know that the previous sun before our sun was bigger was because timewise and because it had to undergo a supernova and had to explode.  Answer questions about the weekly textbook reading: What did you learn?
