Week 8 : Geology that kids see

 

  1. What did you do in lab today? This week in lab we did an experiment that required us to observe different types of sand. We spent time observing different characteristics of each type of sand such as it's color and size. After we observed it, we made an educated guess as to where the sand is from (desert, river, beach). 

    ​
  2. What was the big question? Where does this sand come from?​
  3. What did you learn in Thursday’s discussion? In this weeks discussion, I learned more about the rock cycle. I learned that there are 3 kinds of rocks (igneous, sedimentary, metamorphic) that may do 3 things. I also learned more about erosion and weathering, and that erosion means the rock has moved, and weathering means that the rock has been broken up. ​
  4. Read the online textbook chapter:                                                                                  What did you learn?​ While reading the textbook this week, I learned that geologists can use the law of superposition and original horizontality to figure out the relative age of a certain layer of a rock. I know that the Law of Superposition allows us to know which layers of rocks are older, but it's interesting that geologist can actually predict a relative age of the rock using this law.                                                                                                             What was most helpful?​ The most helpful part of the textbook for me was the section over weathering and erosion, specifically the key takeaway. It's sometimes hard for me to remember which one is breaking apart the rocks and which one is moving them, but this section allowed me to better understand that weathering is "making the mess" and erosion is "cleaning up the mess".                                                                                                  What do you need more information on?​ I would like to learn more about water erosion. We didn't get to talk about this too much in lecture or lab this week, and the textbook doesn't cover much about it. I plan on doing my own research, however, to better understand this concept. 
  5. What questions, concerns, and/or comments do you have? Learning about the layers of earth in lecture this week was really helpful and helped me clear up some of my confusion. It's easy for me to remember which layers and older and younger, but when there are figures coming out of each layer it gets a little confusing, so the time we spent in lecture on Thursday discussing that was really helpful.

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 5 Galaxies to Black Holes

  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. ​ 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.  ​ 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 in...

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:                    ...
