 1.  The big question addressed in the lab, and a description of what you did. This week in the lab we started talking about the timeline of when things started to live on earth. Our big question was, what are the significant events in the history of the earth and when do they appear in our timeline? To answer this question we took events of when things started to appear on earth, e.g., humans and dinosaurs, and placed them on a timeline to show when we thought they appeared. We then learned about when all of these things would have appeared on earth. We did this by looking at earth’s history as a clock and using earthviewer.  2 . A description of what you learned in Thursday's lecture.  Exam this week. 3. Answer questions about the weekly textbook reading: What did you learn? At the beginning of the textbook it talks about geologic time and it breaks down every part of when things arrive on earth. It starts with the earth forming and then finishes when homo sapiens ...

The big question addressed in the lab, and a description of what you did. This week in the lab we had presentations about different parts of the universe. First we learned about the origin of the universe. The universe is 13.8 billion years old. Then we learned about life cycles of stars. A cool fact about stars was that the bigger a star is the shorter its lifespan. Then we moved onto learning about galaxies. We learned that there are three types of galaxies, spiral, elliptical, and irregular. We also learned about the origin of the earth. We learned that the earth has many layers including the crust, the mantle, and the core. Black holes was the next topic we learned about. Black holes are formed when a star is at the end of its lifespan. Lastly we learned about the exploration of space. I thought that it was interesting to hear that women should have the ones going to space for many different reasons but we used to not be allowed. A description of what you learned in Thursday's ...

The big question addressed in the lab, and a description of what you did. With your group members, physically BUILD, using whatever you have access too, a scale model of the sun and the 4 inner planets. Include the moon (our moon). How big is the solar system? To answer this big question we built a model of the solar system. We included the sun, moon and 4 inner planets. We were told this to scale. So we had to figure out the appropriate size that our planets needed to be to be able to fit within our distance we had. We started out by making the planets pretty big but realized that the scale was to big and we did not have enough room to spread all of the planets out as they should have been. For example the earth was the size of a grape. But after we started over and made our planets a lot smaller we were able to fit everything. These were the size comparisons for the planets: Sun: head of lettuce  Moon: grain of salt  Earth: mustard seed  Venus: a little bit bigger than ...
