  https://youtu.be/Gor3dTSgwp4 Lab I was not in lab this week, but from what I read and looked at, we thought about when things first appears on earth, such as humans, dinosaurs, plants, and animals. We then placed the answers that we were thinking about on a timeline. We investigated what the significant events in the history of the earth are. Noting the importance of the event, when it happened, and placing it on a timeline. We also brainstormed questions to investigate about earthquakes and volcanoes and how they relate to earth's plate tectonics.  Thursday's Discussion We had our exam so we did not learn or talk about anything new this time.  Pressbook: - I learned that earth was formed around 4.65 billion years ago. I learned that humans came about a long time after rocks, prokaryotes, oxygen, organisms, animals, and plants. I also learned that planet earth was in ice a couple of times and this was called the snowball earth. I learned that because of plate tectonics,...

  What did you do in lab today? In lab today, we learned about the Origin of the Universe, specifically around the Big Bang and different misconceptions around it. One misconception is that the Big Bang created our entire universe and that it was an explosion. We also learned about stars, the life cycle of stars, the origin of the earth, how the earth formed, galaxies, and black holes. We learned about these through different presentations. Black holes are very dense and nothing, not even light, can escape from them.  What was the big question? The big question this week was around the timeline and origin of the universe. Everything we were learning about, such as the life cycle of stars, the origin of the earth, the earth formation, galaxies, and black holes all tie together of the big phenomena of the origin of the universe. What did you learn in Thursday's discussion?  In Thursday's discussion, I learned that water rotates clockwise in one hemisphere, and on the other ...

What did you do in lab today?  In lab today, we got into groups and built a model of the sun, the moon, earth, mars, venus, and mercury. This model needed to be to scale, so we converted the actual distance of the moon and the four inner planets from the sun. We used the sink as our sun, and calculated the different distances going all the way out to the hallway. It was really difficult to think of ways to convert the actual distances in order to make it to scale. This took a lot of trial and error because some of our conversions made it way too small to make the planets, so small that they would be specks of play dough. We also got to explore how the earth is compared to other planets to put things into perspective of just how big our solar system is.  What was the big question? The big question that we were investigating this week is how big is the solar system? We got to get a good idea of this through the physical model of the solar system that we built in lab.  What ...

 What are your best understandings about?... 1. How the phases of the moon occur?  The sun covers the moon in different phases and only shows parts of the moon at certain times. Waxing gibbous, waning gibbous, crescent.  2. What causes the seasons?  The way that the earth is turned or rotated on the axis and with the hemispheres. 3. What causes a lunar eclipse?  When the sun is directly in front of the moon.  What did you do in lab today?  The questions above are ones that I answered before we started investigating in lab. As seen above, I only had some ideas as to how the sun, earth, and moon work together. I believe I had some prior misconceptions before we began investigating. In lab, we were able to better visual how the moon, earth, and sun work together with the different globes we had, styrofoam balls for the moon, and the light bulb for the sun. After better explanation and visuals, I was able to see that the sun does not cover the moon to make...
