week 10

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

    Our big question addressed in the lab this week was, what are the layers of the earth? How do plates move? What evidence do we have? To begin this week's lab we talked about the different layers of the earth. There are four main layers of the earth. The crust, mantle, inner and outer core. We also talked about convection currents. These are currents of liquids heating up and cooling making it so there is a constant circulating flow of liquid. After that we made different types of rocks using starburst and heat. We made sedimentary rocks which are cemented and compacted together. We made igneous rocks which melted and then cooled. Lastly we made metamorphic rocks, we heated, but not enough to melt, and were pressured together. 

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

    This week in lecture we talked about earthquakes, volcanoes, plate tectonics, and the rock cycle. We learned that there are three layers of the earth including the crust, mantle, and inner core. We learned that most volcanoes lay on the plate tectonic lines around the world. When looking at the map of the plate tectonics, we saw that the volcanoes were mostly all on the lines. We also talked about the belief that everything used to be one supercontinent. We believe this because there were certain plants and animals found in different continents that would match if the continents were connected. We also talked about weathering and erosion. Weathering is the process by which rocks are attacked by the environment. Erosion is the movement of sediment. Including water, wind and glaciers.  

Answer questions about the weekly textbook reading:

What did you learn?

    I knew about most of this information before reading this week's textbook but I did learn a lot about volcanoes. A volcano is a vent that allows magma, rock fragments, ash, and gases to escape to the surface of a planet or moon. I learned that there are two different types of volcanic eruptions, explosive and effusive. Effusive eruptions are when lava steadily flows out a volcano onto the ground. It happens when magma reaches the surface. Explosive Eruptions are when the magma is fiercely fragmented and rapidly expelled. This happens when cooler magma reaches the surface. Volcanoes can be formed in 3 ways, converging tectonic plates, diverging tectonic plates or over a hot spot. 

What was most helpful?

    I found all of the images and examples to be very helpful. Through the how pressbook there were images that went with what we were learning, whether it was plate tectonics, valones, etc. Everything was explained very well and it made it a lot easier to understand the information. 

What do you need more information on?

    I want to know more information about ways we can teach this to young students. I feel like this information can get confusing for some of the younger kids and I want to be able to teach it in a fun and exciting way but they are still getting the information. 

What questions/concerns/comments do you have?

Week 14

  The big question addressed in the lab, and a description of what you did. Our big question this week in the lab was, how do greenhouse gases work? The greenhouse effect is when gases in the Earth’s atmosphere traps heat from the sun and this is what keeps the planet warm. Without the greenhouse effect, the Earth would be cold. This is the “cycle”: Sunlight comes in and warms the Earth’s surface  The earth gives off some of the heat as infrared radiation  Greenhouse gases (carbon dioxide) trap some of the heat and stop it from escaping into space  This is what keeps the planet warm.  We looked at lots of graphs that showed us how much carbon dioxide is in the atmosphere. One of the graphs I found very interesting was the one from West Branch, Iowa. The graph shows data points starting around 2008 and going up to 2022. We see in the graph that carbon dioxide levels get higher and higher every year and then they don’t go low. The data points go up and down in a s...

Week 8

The big question addressed in the lab, and a description of what you did. This week in the lab we had presentations about different parts of the universe. First we learned about the origin of the universe. The universe is 13.8 billion years old. Then we learned about life cycles of stars. A cool fact about stars was that the bigger a star is the shorter its lifespan. Then we moved onto learning about galaxies. We learned that there are three types of galaxies, spiral, elliptical, and irregular. We also learned about the origin of the earth. We learned that the earth has many layers including the crust, the mantle, and the core. Black holes was the next topic we learned about. Black holes are formed when a star is at the end of its lifespan. Lastly we learned about the exploration of space. I thought that it was interesting to hear that women should have the ones going to space for many different reasons but we used to not be allowed. A description of what you learned in Thursday's ...

The big question addressed in the lab, and a description of what you did. With your group members, physically BUILD, using whatever you have access too, a scale model of the sun and the 4 inner planets. Include the moon (our moon). How big is the solar system? To answer this big question we built a model of the solar system. We included the sun, moon and 4 inner planets. We were told this to scale. So we had to figure out the appropriate size that our planets needed to be to be able to fit within our distance we had. We started out by making the planets pretty big but realized that the scale was to big and we did not have enough room to spread all of the planets out as they should have been. For example the earth was the size of a grape. But after we started over and made our planets a lot smaller we were able to fit everything. These were the size comparisons for the planets: Sun: head of lettuce  Moon: grain of salt  Earth: mustard seed  Venus: a little bit bigger than ...
