Week 7: Rocks and the Rock Cycle Blog

 1. What did you do in lab today? 

Today in lab I had to leave early due to School of the Wild with prior communication with Alexis and Ted. However, while I was there we did a formative assessment over rocks, which humbled me greatly as I thought I knew what a rock was, but I was very wrong. Next, we looked at different probes we can use as formative assessments and looked at books with plethoras of probes we can use, which was super heloful and definitely a resource I will use in the future. Then, we talked about assessments, and how assessments do not tell us what our students really know, and looked at an example of this with packing parachutes. Then, I reviewed the slides since I had to leave and what was done in lab today, after I left, they reviewed questions from the exam we took last week, and they set the curve for the exam. Next they reviewed the course feedback formative assessment we did. After, they reviewed our reading response that was due on Sunday, and lastly they did an experiment on the rock cycles of the three types of rocks. 

2. What was the big question? 

I think that there were two big questions in lab this week, the first one being: Why should we not judge how much our students understanding off of an assessment grade? And: What are the changes each type of rock goes through when there are changes to heating/cooling/pressure/or color? 

3.What did you learn in Thursdays Discussion? 

Metamorphic: 

  • Big change 

  • Can go through weathering and erosion and become sediment 

Sedimentary: 

  • Sediment 

  • Can get pushed into magma and melt 

Igneous: 

  • Born from fire 

  • Can go back into magma again and melt 

  • Or can go through weathering and erosion and become sediment 

  • Could go through heat and pressure and become metamorphic 

Buoyancy: 

  • The pops with sugar sunk because the sugar makes the pop denser than the water outside 

  • The diet/zero sugar pops floated because there is not an sugar so it is not denser than the water in the tank.

Specific Gravity: 

  • Specific gravity=W(air)/(W(air)-W(water))

Online Chapter

1. What did you learn? 

I learned that rocks are classified into 3 different types, Igneous (magma cooling), Sedimentary (particles called sediments compacted together), and Metamorphic (from existing rocks undergoing heat or pressure). I also learned about geodes which are when a cavity forms in a rock creating a geode. Within geodes they are different colors and can have different minerals.

2. What was most helpful? 

What was most helpful for me in this chapter was how the three different types of rocks were broken down and I was given information on each of them and the characteristics of how each of them form which helps me understand the differences between each type.

3. What do you need more information on? 

I think I need more information on rocks and what happens to rocks over time,  do they ever change?

4. What questions/comments/concerns do you have? 

Does every state have geodes?

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...
