 Olivia Langosch What did you do in lab today? I was not in lab today, but after reading the slides I learned that greenhouse gasses are gasses that absorbs and re-emits infrared light. This has created more CO2 in the atmosphere. It has gone up about 10 parts per million in a year and a half.  In the simulation, as I put the amount of greenhouse gasses to lots, it created more infrared photons. If we continue with increasing CO2 in the atmosphere, there will be more infrared photons released and back into the atmosphere, which creates more CO2 back in the atmosphere.  What did you learn in Thursday’s discussion? In lecture, I learned about how humans produce a lot of carbon dioxide. 25,000 parts per million. 200,000 year run of humans. Things will start to disappear that humans need in order to survive, this will make humans extinct. Snowball, major Ice Age. The Albedo Effect is when sun lets off energy, the different colors reflect differently, lighter things reflect mo...

 Olivia Langosch  What did you do in lab today? Weather is day to day. Climate is the average of weather over a thirty-year period.  "Weather is your mood, climate is your personality." "Climate is what you expect, weather is what you get."  The Goldfinch is going to move up North, hotter and humid here, not environment that it likes.  We also looked at data in the slides about climate change and we made this paragraph with our table group about the data we found:  Climate change can be seen in many of the diagrams that we were presented with. One that we noticed that had data which helps prove climate change is happening is the Snowy december chart where it showed that in 2007 there was 20.27 inches of snowfall, and in 2019 there was only 1.1 inches. This shows that there must have been increasing temperatures because snow was not able to form and therefore snow and low temperatures have drastically decreased over the last 10 years. Another chart that we f...

 Olivia Langosch Some common themes we talked about were:  * How people are in denial of the impact on climate change, but it's. real thing.  * Humans are a big factor in climate change  Major issues we talked about were:  * Cows and eating beef * Fracking  * Deforestation We want to ask:  * Is the planet able to even be saved at this point?  How we can address them:  * Make scientists findings public for others to read about, or thing about.  I learned that climate and weather are different things. Climate is a 30 year average of weather.  We also talked about the climate change, and discovered different parts of Iowa and how we think the Goldfinch is in danger. The picture below is our research in the middle bottom part of Iowa, "Duke". 

Olivia Langosch In lab, we looked at a bunch of different types of sand under a microscope. We looks at 11 different sands up close. We described the characteristics of each type of sand, whether the sand was opaque, clear, colorful, types of sizes, etc. Then, after that we got to guess what sand it was from, glacier, wind, or water. Those are the pictures below.  In Thursday's discussion, I learned that when something is more dense, it sinks. When something is less dense, it floats. We tested this with different cans of liquid in class. We also talked about, through the book, Archimedes, about density in general. We tested the density of the "gold" in the water to test if the "gold" was dense or not.  From the pressbook, I learned that sand is weathered down, or broken down rocks. This can either happen from wind or water. I also learned that black sand is from lava, that was cooled, making it igneous rock, and found near volcanoes.  The most helpful was the li...
