Week 5 Galaxies to Black Holes

 

  1. What did you do in lab today? This week in lab we presented our projects to our class. My group presented over The Lifecycle of Stars. Other groups presentations consisted of Meteors, Meteorites, Craters, and Comets, Galaxies, and Black Holes.​
  2. What was the big question? The big question for this week revolved around the presentations, as each group came with a set of multiple choice questions that allowed the listeners to think deeply about the content that was discussed. ​
  3. What did you learn in Thursday’s discussion? I learned more about galaxies in Thursday's discussion which helped me understand them better. I learned that there are 2 trillion galaxies, that each galaxy has about 200 billion suns, and that a galaxy is just a collection of hundreds of billions of stars. Furthermore, I learned about Katie Bouman and how she is the person who took the only worthy picture of a black hole. Lastly, I learned more about the inner and outer planets, and that the inner planets only have 3 suns- 1 on Earth and 2 in Mars. ​
  4. Read the online textbook chapter:                                                                                  What did you learn?​ I learned that the asteroid belt is located between Mars and Jupiter, and that it contains a vast majority of asteroids known as minor planets. I also learned more about the Milky Way, and that at the center of it is a black hole named Sagittarius A, which has 4 million stars.                                                                                                              What was most helpful?​ The section under Meteors and Meteorites were most helpful to me. This section included definitions and key concepts of meteors, comets, and asteroids. This was helpful to me because I find these terms to be confusing, so having a clear definition on what they are and what they do was very helpful.                                                 What do you need more information on?​ I would like more information on Black holes. Though the textbook did a good job at explaining what they are, it is hard for me to fully comprehend what a black hole really is. I know it is not an actual hole, rather a space, but I don't fully understand them. How would the universe/ galaxy be different without blackholes? Or would it exist at all without black holes? 
  5. What questions, concerns, and/or comments do you have? As I previously mentioned, I am still not too confident about meteors and meteorites, and all that stuff. I would like to spend more time in class covering these concepts to get a fully understanding of what they are, their purpose, etc.

Week 15

  What did you learn this week?  This week we learned and explored how to create a lesson for 5th graders using phenomenon to learn about the conservation of matter. We used baking soda, vinegar and other tools like a scale, balloon, and funnel to explore this investigation. We had to participate in multiple experiments before we found a structured way we could explain this phenomenon to students. There was a lot of trial and error, for example we realized that using a balloon wasn't the best way to demonstrate the conservation of matter, so we had to adjust our experiment. When we adjusted our experiment, we took away the balloon and added baking soda by using a test tube into the soda bottle. Overall, I learned that there are many ways that teachers can demonstrate the conservation of matter to students, but it is our job to figure out the best way to demonstrate this to students.  How can you apply what you learned to your teaching in the future?  I plan on applyi...

Week 1: Earth Moon System

  What did you do in lab today? In lab, we talked about why we have seasons. We specifically talked about how the seasons work based upon direct sunlight and how much sunlight is hitting the surface of the earth at a certain time. We discussed how seasons happen when direct sunlight hits a tropic (northern and southern line).        ​ What was the big question? The big question that we were answering these 2 days was "Why do we have season?"  ​ What did you learn in Thursday’s discussion? In Thursday's discussion, we also discussed why we have seasons, specifically talking about how being closer to the sun does NOT mean it is warmer. We specifically discussed Aphelion, which happens around July 5th, and how the earth is 94,500,000 miles from the sun; and Perihelion, which happens around January 4th, when the earth is 91,400,000 miles from the sun.  ​ Read the online textbook chapter:                    ...
