Week 7: Rocks and the Rock Cycle - Science Methods II (Addy Junge)

Week 7: Rocks and the Rock Cycle

1. What did you do in lab today?​

  • During lab, we started off with our formative assessment, posing the question "Is it a rock?" After that, we got the chance to look at assessment probes that provide science teachers with questions to get students thinking. This also helps us figure out what our students already know. We also reviewed our exam grade/curve while discussing grade inflation and our Activitymania assignment. During our lab activity, we discovered a little more about the rock cycle and how different rocks are made. We did this by using Starburst and melting them in different ways (using different colors, different melting strategies, mixing the Starburst, etc.). 

2. What was the big question?​
  • I would say the big question during our lab would be "How do different types of rock form?"
3. What did you learn in Thursday’s discussion?​
  • Here are my notes from our lecture:
4. Read the online textbook, chapter 1:
  1. What did you learn?​
    • I learned a little bit more about igneous, sedimentary, and metamorphic rocks and their characteristics. I also learned a lot more about Geodes. I know we talked about it in lecture, but I did not know that they could form in sedimentary rocks here in Iowa. This chapter also touched on Archimedes' Principle and included a video on that topic. In the TED Ed video, it mentioned how the density and volume would make the water overflow. This relates back to finding out whether or not a Geode is hollow. If the Geode is solid, the specific gravity should be 2.7. Anything less than 2.7, and the Geode would be more hollow. 
  2. What was most helpful?​
    • The part in this chapter that helped me the most was the bullet points under igneous, sedimentary, and metamorphic rocks. It made it less intimidating to read and more engaging. I also enjoyed looking at "The Rock Cycle" image. It helped me see how heat, pressure, cooling, and melting affect the different types of rocks!
  3. What do you need more information on?​
    • I think I need more information on how the specific gravity formula works. 
5. What questions, concerns, and/or comments do you have?
  • A comment I have is that I took Introduction to Earth Science and Natural Disasters in previous years. I'm curious to see how these courses will all connect and how they will differ.

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...

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...
