Week 14: December 2 - December 6


What did you do in the lab this week/ What was the big question: 

( I was absent from class)

 In lab, we started by talking about our elder's interview. I chose to interview my mom and found that many people in the Mexican community don't know about climate change. My mom knows it's getting hotter in summer and that winter is getting colder. But never taught about climate change.

 How has global warming work? The earth's atmosphere contains gases like carbon dioxide, methane, and N2O that trap heat from the sun. This natural process is called the greenhouse effect. Without it, our planet would be too cold to support life as we know it. 


What did you learn in Thursday's lecture?

I learned that the three big factors impacting climate change are solar radiation (sun), volcano activity, and human impact. I learned about the Albedo Effect, which is a measure of how sunlight a surface reflects back into space. It is expressed as a percentage: a high albedo means a surface is highly reflective, while a low albedo means it absorbs more sunlight. Students already have experience with this and as teachers, we can create an experiment. You can place a ice on a white shirt and a black shirt. Students can study how fast the ice melts.

Answer questions about weekly textbook readings:

1. What did you learn? In chapter 23, I learned that the ice-melting will mess up the ocean cycle, but adding more cold water. This will negatively affect the plant and living creatures in aquatic ecosystems which affects marine-based economic industries, such as fishing. This is something that is slowly happening but has big effects. 

2. What was most helpful? It was helpful to watch the videos and visuals. 

3. What do you need more information on? Nothing, I feel good about this week's content. 

4. What questions do you have? No questions

    Elementary Science II Week: October 21th - October 25st  What did you do in lab this week? / What was the big question?  The two discussion topics for this week's lab is geologic time and earth viewer. We began by looking at a presidential elections are impacted by a 100 years old coastline. We learned that parts of the south were underwater as a point in history, flowing the blue line. Then as a class we got to place events on a number line ranging from humans appeared to moon was created. This allowed use to visual see how far away it took earth to become what it is now. It also helps break the misconception that after the big bang earth just appeared. Now that we have learned many things about our universe we answer the question on how to now placed them in order. If we put  all the formations of the Earth on a time line humans have only been part of the timeline for 2 million years.     Answer questions about the weekly text books readings...

   Elementary Science II Week 13: November 18th- November 22th What did you do in the lab this week/ What was the big question:  We started by talking in our groups about the two articles, Couple Inquiry and Sweater, and about how similar and different they are. Both talk about teachers letting go of the control. I think that is something a lot of us are not used to or have never seen. Even as a college student, I am used to being told what to do and study for. To then move to allowing students to take over the lesson can be hard. But both articles make a great point. The sweater article talked about how students naturally lead a lesson if and only need a little bit of guides. The Coupled Inquiry talked about allowing time for freedom but with guidance.  A fun fact that I learned is that Americans are lagging in academics and despise the free education we give. I find it interesting but also not shocking. In all my travels I have seen how smart students can be withou...

What did you do in lab this week? / What was the big question?  My group's big research question was about the earth's origin. There are so many misconceptions about how the Earth was made, for example, the Earth was formed instantly. Historically people used to believe that the Earth was the center of the world. We learned that current science understands that Earth is 4.65 billion years old thanks to geology and fossil studies we were able to set a date for the Earth.  We also got to hear from other groups about the origin of the Universe, the lifecycles of stars, galaxies, Black holes, and exploration of spa...
