Week 10 Blog Post

 

  1. What did you do in lab today?
    1. This week in lab we got to discuss the investigate the different types of rocks and how they are made. We got to use starbust and a small blow torch to form and shape the different rocks. The picture below shows the different rocks we made and two of the rocks at different stages of theri formation. We also talk a lot about our exam that we jsut took and went over those ideas as well. 


  2. What was the main lab question?
    1. How are rocks formed?
  3. What did you learn in Thursday's discussion?
    1.  This week in lecture, I learned about plate tectonics, and how pangea happened. The idea of pangea shows the reason while plate tectonics conintue to move. We also learned about ridges and how the ridges tell us how old it would be on the coastline. 
  4. Online Textbook:
    1. What did you learn?
      1. Something that I learned was the was about geode. A geode forms when a cavity forms in a rock, which can occur in different ways. I didn't what this event was or that it was something that could helpful so this is something that I had learned through the pressbook. 
    2. What was most helpful?
      1. One thing that was most helpful that whole process of the rock process. I had no idea how rocks were created and formed or what was techinaly considered a rock. The key processes in the rock cycle are heat & pressure and weathering & erosion, which is also something I never knew helpful for me to understand.  
    3. What do you need more information on?
      1. One thing I need more imformation on is Archimedes’ principle becaue I am not really sure I understand it. In the pressbook it says that the Archimedes’ principle says that the weight of the displaced liquid is equal to the weight of the object. I am not sure how this related to rocks though. 
  5. What questions, concerens, and/or comments do you have?
    1. How do we know if soemthing is a rock?
    2. Why are there different types of rocks?

 This week was really interesting to me. We got to really dive deep into the M&M experiment we tried last week and got to change different variables. It was also interesting to hear about the other tables because we all got to experiment with different ideas and use different ways to find them. One thing that I learned was the capture of the water influenced how fast the colors bled. Overall, the orange M&M bled the fastest while the blue bled the slowest. It was also interesting to see that the sugar water made the colors bleed very slowly and contained around the M&M, while the waters with no sugar bled and spread. Overall, I thought this activity was really fun and interesting to complete and think about. I think this would be a great activity to complete in an elementary classroom to get them to start thinking about ideas like this one.

 This week in class, we learned about the ideas of DNA and RNA. In this topic, we learned the differences between the four bonds within. For example, in DNA the four bonds are A and T and then C and G. In RNA there is no T, so the letters are A and U and then C and G. This is how the strands work. We also learned about mutations and how they can affect the DNA strand and also how a mutation works in a DNA strand. This was really interesting to learn about and can benefit my future students because it will help them also understand the way they look. Lastly, once again, we looked at our plant and got to see the growth of our plant. Unfortunately, it is getting very dry and starting to die a little. Overall, I enjoyed learning about DNA and RNA this week.  Our plant from this week!

 During this week's class, we got to explore many different hands-on labs. The main point of this activity was to discover the why. Many young students want to know why, but we don't know how to explain it. We can understand what is happening and why it's happening, but how do you explain this to someone who doesn't understand. I think that this was a really interesting way to explore this idea. We discovered so many different things during this activity. The most interesting one was the baking soda and vinegar. We knew as older students what was going to happen, but we were not sure how it happened. I think that doing these experiment help us learn how to teach ideas like these, but also can help students in the classroom ask question and be curious during experienmenting. Asking question is a good way for studetns to learn and start to understand they why of things happening. Here is two of the different acitivites that we did!   Ice melting ^^^ Plunger Push ^^^
