Lab Notes : Creating a timeline. We also looked at the earth viewer simulator. We came across 5 different time period events. One of them that really stood out to me was the Permian Extinction this one happened 251 million years ago. I also found the snowball earth glaciation to be interesting which took place 715 million years ago. This is what spread ice around the globe and I found that fascinating. Lecture : We took the space quiz in lecture! Textbook: I thought reading about the space race was very interesting information as it also went into things extensively on also how the full process worked. I learned about when this was all kicked off and what the timeline entailed. I thought it was very helpful seeing the timeline and dates laid out for what year all events occured. I would like more information on what people did to educate peers that were confused or struggling on topics.

Lab : Today we had our space presentations. The 6 main topics were the origin of the Universe, the Lifecycles of Stars and galaxies, the Origin of the Earth, black holes, and exploration of space. For Black Holes, I learned that Black holes are formed when a big hole is at the end of its life when it becomes too weak to support its own gravity and collapses on itself. Black holes can also be of different sizes. The parts of the black hole include the event horizon (point of no return), the singularity (center of the black hole gravity becomes super intense becoming infinite), and the accretion disk (found on most black holes is the ring of gas and dust). My group presented on Galaxies, and when I thought I knew a lot about it already, I gained more information yet again. Galaxies consist of stars, planets, and vast clouds of gas and dust, all bound together by gravity. Galaxies are known to also come forward in a variety of shapes, like spirals and ellipticals. Galaxies are typically o...

Lab : In the lab for week 7, we were designed to physically build a model of the sun, moon, and the four inner planets. We were instructed that this needed to be by scale. The hardest part was getting each of the planets, the sun, and the moon to be the exactly correct size that it would relate to in real life. We then had to space out all 6 of those in the correct distance that it would be in real life as well. After lots of errors and trials, we finally got all 6 of them to the right distance. Overall, I take away from this investigation just how spread out the moon is from the sun. It was a good way to hands-on work on this by visually being able to tell how spread out everything truly is. Weekly Textbook Reading : Our Solar System- The four inner planets are Mercury, Venus, Earth, and Mars. They are all considered rocky planets because they have a solid outer surface, this was a helpful reminder once again. It was most helpful reading on the section regarding the Sizes and Distance...
