Week 5: Galaxies to Black Holes

 What did you do in the lab today? 

-Today in lab, we listened to groups present about multiple topics. Something I learned is that there are three different types of galaxies; the Milky Way is a Spiral Galaxy. Our Solar System takes 240 million years to orbit the Milky Way. 

What was the big question? Timeline of the Universe

What did you learn in Thursday's discussion? 

The sun is held together because of its mass, so as it loses heat and light, it has less mass, and then it loses gravity and begins to inflate (red giant)

Textbook: 

What did you learn? 

The sun can only burn atoms up to Iron. When a star goes supernova, it is so powerful that it builds the rest of the periodic table

What was most helpful?

 I think it was most helpful how you split up each concept and told us the definition and the key concepts. I think that is super helpful, that way I know what I need to remember and what I don't need to worry about. 

What do you need more information on?

I am still confused about how shadows/phases of the moon work based on where the sun, moon, and Earth are lined up. 

What questions, concerns, and/or comments do you have?

Week 15 Blog post

                                                         What did you learn this week?       No matter how substances react during a chemical reaction, there is as much matter before the reaction is the same as there is afterward. To explain this phenomenon to a 5th grader, we weighed the baking soda, vinegar, and the bottle. After we had weighed the ingredients separately, we combined vinegar and baking soda in the bottle. After 30 seconds, we weighed the baking soda, vinegar, and the bottle. We saw that even though they mixed together to create a chemical reaction, the weights were still the same, because of the conservation of matter.  How can you apply what you've learned to your teaching in the future?  In the future, I can conduct this experiment with my students. We can use scales, a...

Week 12: Climate Change

Image
 What are the primary points in the video?  -Powerful people and lawmakers do not believe climate change is real, and are not slowing down productions that influence climate change. Burning fossil fuels and drilling in the Arctic are causing glaciers to melt, Miami to flood, and droughts to occur.  What are the major issues? -Burning fossil fuels vs. alternative options, but alternative options are expensive -Meat and oil for cooking have huge impacts on releasing CO2 into the atmosphere  -The Positive feedback loop between rising temperatures and causing glaciers to melt, which is causing temperatures to rise even more What questions do you want us to teach you?   -We don't ever learn how to prevent climate change on the local level How would you like us to teach you? -No preference  What did you do in the lab today? Today in the lab, we calculated the average rainfall in the Northern Central region of Iowa. We calculated the average. rainfall from 1900-19...

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

Image
  What did you do in the lab today?  Today in the lab, we created the four examples of what happens at plate boundaries. The Graham crackers/rice cakes act as a plate, and the whipped cream is magma. We conducted four examples of what happens to plates when they collide, sink, or spread apart. What was the big question?  -What are the layers of the Earth? -What is the Theory of Plate Tectonics? -What can form at the three types of boundaries? What did you learn in Thursday's discussion? I learned that the Appalachian mountains were once connected to mountains in Africa, but the Appalachian mountains experience more erosion, so they are shorter in height than the mountain range in Africa.  Textbook: What did you learn?  -The flow of liquid metals creates Earth's magnetic field, which is why compasses always point north. The magnetic field protects the planet from extreme weather and radiation in space  What was most helpful? I like the images of the continen...
