 Lab:

In the lab, we worked on modeling the sun and some planets to scale. My group decided to use a clock for the sun and playdough for the planets. I didn't realize how small our planets would be compared to the sun. When we were given sticky notes to put behind the planets we made, I was shocked to learn that's how small they are compared to the sun. It was interesting to see the solar system mapped out in Lindquist because it seemed large. Knowing this model was to scale, made me realize how large the solar system is. It was helpful to see the objects in 3D because I'm used to only seeing 2D pictures or diagrams in textbooks. 







Lecture:

We learned that as teachers we should teach science with data and let kids draw their own conclusions. We also learned that Theia created the moon. Theia hit the Earth and some of the leftover debris created the moon. The moon and the Earth slowly move farther away from the sun yearly. They move about an inch away each year. It was interesting to learn that our shadow is always pointing North when we're in Iowa. I never knew this before because I thought our shadow moved around/changed direction depending on the time of the day. 


Pressbook:

From this pressbook chapter, I learned that the gaseous planets grew in size. As their gravity increased, they were able to collect materials from space to make the planets bigger. I also learned that Pluto isn't a planet because it doesn't meet all three requirements to be a planet. It was interesting to learn that a planet has to be able to clear the neighborhood. I never knew that scientists were able to discover that planets were capable of doing this.

 Lab: The Earth is made of the core, mantle, and crust. The hot air rises from the crust, cools at the crust, and then goes back down into the core. Mountains are created when the plates collide. It causes the Earth's crust to crumble, fold, and rise up into mountains. Earthquakes occur when the plates move away from each other.  Lecture: This week we focused on the sea floor and the movement of the plates and ridges. The ocean basin gets older as you move from the middle of the Atlantic toward the African coastline. The ocean sea floors don't spread at a consistent rate over time. We can average how much they move in a hundred years or a year but the results won't be the same. It depends on the time because it isn't a set rate. In lecture, we also learned that the spreading of the sea floor is measured in mm/yr.  Pressbook: In this week's chapter, I learned why compasses always point north. It's because the flow of the liquid metals in the Earth's core crea...

 Lab:  This week in the lab, we worked with our groups to examine samples with the microscope. We looked at eleven different samples to decide if they were developed through water, glacier, or wind. For some of the samples, it was hard to decide how they were developed. We thought most of the samples were developed by glaciers, but after analyzing the correct answers, we realized our results were very different.  Lecture:  I learned that something more dense than water will sink. The diet coke has less sugar than the other pops so it floated. Water displacement can help collect accurate measurements. The container needs to be completely full and you need to measure how much water is displaced from the container to get accurate results.  Pressbook: In the pressbook reading I learned if the specific gravity formula equals 2.7, it's likely the geode is solid quartz. Like the experiment we did in lecture, if the formula is less than 2.7 the geode is probably more ho...

 Lab: In lab this week we learned about the Earth and its timeline. Our first life forms on Earth started in the water. Fish were on Earth before plants appeared 440 million years ago. Once land plants were on Earth, amphibians were able to have food to survive. Pangea occurred 335 million years ago. The first dinosaur appeared 225 million years ago. I was interested to learn that oxygen wasn't always on Earth.  Pressbook:  The pressbook described the timeline of the Earth and how it was created 4.67 billion years ago.  The Earth was covered in ice about three times in Earth's history.  To melt the ice, people believe volcanos continued to erupt under the ice layers. Later on, the continents were created when Pangea broke apart into pieces. Scientists, including Wegener, believe Pangea existed because fossils spread throughout the continents. It shows that animals could walk to different continents since they were all connected in Pangea.
