Week 8

Week: October 14th - October 18st 


1. What did you do in lab this week? /What was the big question? 

My group's big research question was about the earth's origin. There are so many misconceptions about how the Earth was made, for example, the Earth was formed instantly. Historically people used to believe that the Earth was the center of the world. We learned that current science understands that Earth is 4.65 billion years old thanks to geology and fossil studies we were able to set a date for the Earth. 

We also got to hear from other groups about the origin of the Universe, the lifecycles of stars, galaxies, Black holes, and exploration of space. One thing I learned about stars is that depending on the mass of a star, when it dies it either becomes a white dwarf or explodes in a supernova. There is only one picture of a black hole and we can only can tell by the light around it. 


2.  What did you learn in Thursday's lecture? 

In the lecture, the earth was not formed by the Big Bang. Earth started as a small dot that was created by a giant cloud of gas and dust. This then expanded to Earth as we know it now. It did NOT come from the Big Bang and appeared. The Earth's tilt was due to Theia, a protoplanet that hit Earth. 

Fun Fact: There are more stars than there is sand on Earth.

Takeaway: Teach more about people who impacted science that isn't a typical white man. For example Jerrie Cobb and more! 

3. Textbook

    What did you learn? We learned that the moon does not rotate one side faces the Earth and has a thinner crust compared to the side that is not visible and has a thicker crust.

    What was most helpful? The video that explained the Big Bang was helpful, by Khan Academy. 

    What do you need more information on? Nothing

4. What questions do you have?
Why do people believe that the Big Bang started everything?

    Elementary Science II Week: October 21th - October 25st  What did you do in lab this week? / What was the big question?  The two discussion topics for this week's lab is geologic time and earth viewer. We began by looking at a presidential elections are impacted by a 100 years old coastline. We learned that parts of the south were underwater as a point in history, flowing the blue line. Then as a class we got to place events on a number line ranging from humans appeared to moon was created. This allowed use to visual see how far away it took earth to become what it is now. It also helps break the misconception that after the big bang earth just appeared. Now that we have learned many things about our universe we answer the question on how to now placed them in order. If we put  all the formations of the Earth on a time line humans have only been part of the timeline for 2 million years.     Answer questions about the weekly text books readings...

   Elementary Science II Week 13: November 18th- November 22th What did you do in the lab this week/ What was the big question:  We started by talking in our groups about the two articles, Couple Inquiry and Sweater, and about how similar and different they are. Both talk about teachers letting go of the control. I think that is something a lot of us are not used to or have never seen. Even as a college student, I am used to being told what to do and study for. To then move to allowing students to take over the lesson can be hard. But both articles make a great point. The sweater article talked about how students naturally lead a lesson if and only need a little bit of guides. The Coupled Inquiry talked about allowing time for freedom but with guidance.  A fun fact that I learned is that Americans are lagging in academics and despise the free education we give. I find it interesting but also not shocking. In all my travels I have seen how smart students can be withou...
