Week 10 Blog: Layers of the Earth, Convection Cells, and Plate Tectonics

What did you do in lab this week? This week in lab we shared our convection cell videos, and then we did a lab about plate tectonics and their movement, and even got to eat our lab supplies. I will attach photos of the lab to show what I did. 


What was the big question? What are the different types of ways plates move, and what do those movements look like?

What did you learn from Thursday's discussion?

Earthquakes:

  • Earthquakes are caused because plates move. 

  • Earthquakes have different levels of power because of the amount of tension that is built up between the plates. 

  • There will be an earthquake big enough to shake the whole world. 

  • Underwater when earthquakes happen it causes tsunamis.

  • An earthquake could not cause the earth to fall in on itself. 

  • Earthquakes do occur in predictable ways, but they can occur in areas that are off of normal pathways due fracking and other things. 

  • There is no correlation with increased earthquake activity and global warming. 

Volcanoes: 

  • There is a volcano that is powerful enough to destroy our continent/parts of earth. (Yellowstone, it is a super volcano) 

  • Lava that flows in the oceans does affect ocean life. 

  • Volcanoes become active and erupt due to plate movement. 

  • Volcanic ash buries things and preserves then, 

  • Volcanoes do occur in predictable areas, but happen off of their normal route due to an influx of materials. 

  • We do not know when a volcano is going to erupt again, but they are constantly monitored by the lava flow/pressure within

  • Plates converge and come together (ocean materials and continental materials) think of if a semi hit a sports car. 
  • If continental materials it each other mountains would form (Think of two semis hitting each other)Magma fills the void if continents are ripped apart


Online Chapter: 

What did you learn? From the online chapter, I learned more about what makes up the inner layers of our Earth- the inner core, outer core, mantle, and crust. I also learned more about Pangea, which is the supercontinent that all of our continents were once apart of before the tectonic plates started to shift, which I find really interesting. I also learned about different types of plate boundaries, and also more information about convection cells which helped solidify my learning from the video I made. 

What was most helpful? The tectonic plate boundaries graphic was the most helpful thing in this chapter for me, because I still mix up the different types of boundaries, so this visual was helpful for me to see the actual differences between each type of boundary. 

What questions do you have? How did continents move so much from the original Pangea? 

Do you have any comments/questions or concerns? N/a

Week 5 Blog Post

                                         Week 5 Blog 02/19/2025  This week, we had lab on zoom, although we were not able to meet in person, we got a lot done and learned new knowledge and also built on upon prior knowledge throughout our zoom lab. We started the lab by going over the five parts of the 5E model which are: engage, explore, explain, elaborate, and lastly evaluate. We then also talked about the lesson plan assignment for this week just to make sure we all understood what we are supposed to do. We then broke up into small groups and made a small google slides presentation over the 5 parts of 5E and what the teacher does in each part and what the student does. Then, we broke back up into our small groups and went over the reader response from last week which was the NGSS classroom video featuring Ms. Copes class and their lesson over changes to the earth and their ef...

Week Four Blog Post

                                              Week 4 Lab Blog 02/12/2025 This week lab was a little different than usual, we had a snow day so the work that we were supposed to do was assigned asynchronously. We learned about a 5E lesson model and what the functions of each section are. Then, we completed an assignment where we had to find the lesson on NGSS with limited information. Next, we had to define the performance expectation of the lesson, and answer 6 reflection questions in regards to 5E. Then, we had to find and write the scientific and engineering practices, crosscutting concepts, and the disciplinary core ideas.  Thinking back to my prior knowledge, learning about 5E was new to me this week but I found it to be very helpful as a future educator. NGSS, I am somewhat getting familiar with due to this class and us exploring it and learning about it often in ...

Week 8 Blog Post

                                              Week 8 03/12/25 Lab  This week in lab we learned a lot. We looked at our fast plants and observed changes we saw. I noticed that the roots of our plant are changing colors and petals are falling off. Then, we shared the baby we created yesterday to the class and talked about dominant and recessive genes. Next, we learned about DNA, mRNA, and Amino Acid sequences and did two simulations that helped deepen our understanding. Then, we did a superhero worksheet where we changed the DNA of a person and made them a superhero and we talked about how mutation happen. Lastly, we talked about our reader response from last week which was about carbon cycles. Overall, we learned a lot this week in lab.  I can relate to what we learned this week to my prior knowledge as I remember learning about DNA, mRNA, and Amino Acids in high s...
