Week 10


The big question addressed in lab, and a description of what you did.


In lab, we made a curve for our last test to be regraded on, talked about convention cells which I learned is how air fryers work, and recreated the rock cycle with starburst. An air fryer will send the air up to heat food. 


For some of the starbursts we changed with pressure like the very top two, for the third one we used heat from a blow torch, and for the bottom one we melted two starbursts with a hot plate

A description of what you learned in Thursday's lecture.

In Thursday's lecture, we learned that sand comes from distant mountains and landforms, not from the ocean floor. We also learned that rocks are naturally occurring mineral collections. Then we got introduced to earthquakes and volcanoes. We learned that Yellowstone is a super volcano that could destroy our continent or parts of the world, like in thousands of years. The debris from this eruption will block out the sun for years after. 
Additionally, we learned that scientists sometimes know when a volcano going to erupt by monitoring activity under the crust. They cannot always detect these activities though. Next, we learned that plate tectonics are why earthquakes/tsunamis/ volcano eruptions happen.

The layers of the earth are like an egg. The layers are  crust, mantle outer core, and inner core . Ali said that we will be focusing mainly on the crust and mantle.










Another thing we learned is tsunamis are earthquakes underwater.





Ali also referenced Finding Nemo.The mask that says P Sherman Wallaby Way Sydney is in a trench.


Plate Facts 
-mountains from previous plate movement 
-Volcanos move from hot spots from plate movement and become inactive 
- each continent is not a plate, more than 7 plates, 16ish plates 
-fossils and where they are found is evidence that plate movement is real 
-older rock is farther away from the ridge,
-igneous has two types : intrusive, extrusive 
--extrusive small crystals, intrusive big crystals
-metaphoric happens from pressure and heat 

Answer questions about the weekly textbook reading:
What did you learn? I learned that divergent plates pull apart from each other and convergent plates push into each other.
What was most helpful? The vocab being bolded and the pictures are very helpful.
What do you need more information on? Maybe what will be on the test would be some good information to have.
What questions/concerns/comments do you have? I am just wondering how to know how to know what information is important. I did not expect to do as bad on the last test as I did.

  The big question addressed in lab, and a description of what you did. In lab, we reviewed more on  "Before the Flood" and then talked about the importance of students being able to read graphs. We also talked about coupled inquiry. Climate change seems more of an issue for island people because they are surrounded by water. One way climate change affects them is because it causes thermal expansion in sea levels which means the water rises. We, Iowans, are surrounded by land so people here pretend climate change is not an issue. Another misconception is that climate and weather are the same thing, but this is untrue. Weather is the current temperature and conditions, climate is 30 years worth of weather. One cool fact about climate change though is that Iowa City is in the top 100 cities for making efforts to prevent climate change. Moreover, coupled inquiry is important because we want our students to ask questions and we want them to learn how to investigate their inquirie...

  The big question addressed in lab, and a description of what you did. In lab, we tested different factors like slope, weight, clothing, and others that could change how fat one goes down a slide. My group decided to test how clothing impacts speed. We felt that thinner material would cause a person or object to go faster down the slide, but that no clothing would go the slowest. We found out that we were right. A description of what you learned in Thursday's lecture.  In the lecture, we learned about gravity and forces like friction. We were not all knowledgeable about the subject but then had a discussion and learned much more about how friction works. One example that stuck out to me was how a magnetic force will act against a gravity force. Like for instance, when I tried to use a magnet to put my roommate's calendar on the fridge the forces of the magnet and gravity were fighting with each other. However, in this case, gravity won because even two of our magnets together...
