Week 10: Layers of Earth, Convection Cells, and Plate Tectonics - Science Methods II (Addy Junge)

Week 9: Earthquakes and Volcanoes

1. What did you do in lab today?​

  • At the start of our lab, we filled out our formative assessment! Then we started off with the question of "Why do we have earthquakes & volcanoes NOT on boundaries?" and a map of the midwest. We started discussing in our groups how this could happen and we talked about ancient faults and oil/gas fracking and their contribution to these "random" earthquakes. We then switched groups to share our convection cell videos/ideas, which was helpful to see different points of view of what a convection cell truly is. Our class continued to talk about cell convection and how it works (in water and in the earth). With that, we also dicussed the earth's layers and where convection cells occur within those layers. Switching gears to our (fun and yummy) lab, where we worked with divergent, convergent, and transform plate boundaries with different materials! Lastly, we wrapped up with talking about the continential drift and the theory behind it. 
2. What was the big question?
  • I would say the big question is "What happens when plate techtonics move and how does that affect the overall landscape accross Earth?"
3. What did you learn in Thursday’s discussion?​
  • Here are my notes from our lecture:
4. Read the online textbook:
  1. What did you learn?​
    • Something I learned while reading this chapter is that although continental plates are thicker than oceanic plates, they are less dense, which is why oceanic plates submerge under continetal plates. I also learned more about the Ring of Fire, which I had already learned in a previous class. It was nice to see and read about it this way, as a future elementary education teacher, which helped me understand it better. Lastly, I learned a little bit more about convection cells and how Earth essentially recycles itself. 
  2. What was most helpful?​
    • The most helpful part of this chapter was the images and movement coming from them, specificially the "Convection Cell" picture. This really helped me see the movement the movement of the magma while also seeing the different types of plates colliding. 
  3. What do you need more information on?​
    • I think I still need a little bit more information on the diffrence between the formation of volcanoes and mountains. 
5. What questions, concerns, and/or comments do you have?
  • A question that I continue to have is how do scienctists know when pangea started to split?

Week 2: Space: The Final Frontier - Science Methods II (Addy Junge)

Addy Junge Week 2: Space: The Final Frontier 1. What did you do in lab today?​ NO LAB. It was a Holiday. 2. What was the big question?​ During our lecture, I would say the biggest question would have been "What were some significant discoveries throughout the years about the solar system and space travel?" Some of the other big questions we discussed were how to measure the Earth, who has been on the Moon, and the possibilities of future space travel. 3. What did you learn in Thursday’s discussion?​ Here are my notes from the lecture: 4. Read the online textbook, chapter 1: What did you learn?​ After learning about everything in our lecture, I learned a lot about other historical moments that led us to numerous space discoveries. Right off the bat, I learned more about Sputnik. I remember hearing about it in school, but it was nice to get a refresher on what it was and why it mattered to the United States. Something that also caught my attention was Dr. James Van Allen's ...

Week 1 Notes: Sun, Earth, & Moon - Science Methods II (Addy Junge)

Addy Junge Sun, Earth, & Moon Lab Questions: 1. How the phases of the moon occur? To the best of my knowledge, the phases of the moon occur due to the rotation and lighting of the Earth and the moon when aligned with the Sun. When aligned a certain way, I believe the Earth blocks the light from the Sun that reflects on the moon. Therefore, we only see the lit part of the moon on certain nights.  Over the course of 28 days, the Moon goes through eight phases, where the Sun reflects on the Moon. As the days go by, the Moon moves slightly, reflecting different parts of the Moon's surface. 2. What causes the seasons? When discussing seasons, I believe it is when the Northern Hemisphere is either further or closer to the Sun. Throughout the year, we experience four distinct seasons that change gradually.  Throughout the year, seasons are caused by the amount of direct sunlight hitting the Earth's surface. Due to the Earth's tilt, the direct sunlight hits differently at diffe...

Week 14 Blog - Elementary Science Methods (Addyson Junge)

Week 14 Blog - Elementary Science Methods (Addyson Junge) May 1, 2025                                                 Figure 1 What did you learn this week? This week, during our lab, we got the option to conduct one of the two phenomena we did during week 11. Our group decided to go more in-depth on the "Melting Ice" lab. We were initially confused as to why the ice melted faster on a metal surface than on a wooden surface. Throughout the lab, we started to gain a better understanding of why the ice melted faster on metal because of the density of particles. We then produced our flip video, for which we had created a layout on a whiteboard (Figure 1). In our lecture, we talked more in-depth about phase changes and why that happens. We continued to look into how temperature affects different atoms/molecules.  Are you able to relate what yo...
