Week 14: Greenhouse Gases, Albedo, Global Warming

Week 14: Greenhouse Gases, Albedo, Global Warming

1. What did you do in lab today? In lab today we looked at an Excel spreadsheet of C02 levels in three different places. There were trends and consistent changes within the spreadsheet describing C02 levels changing. My group described how the numbers trended up as the years went on meaning greenhouse gases were warming the earth contributing to C02 levels rise.

2. What was the big question? The big question was how does climate change work. We explored this by using saying certain gases in our atmosphere act as like a blanket around the Earth. Light rays come from the sun and they contain visible photons. Visible photons are absorbed my the Earths surface and infrared photons a re-emitted which is what we know as heat we feel.

3. What did you learn in lecture? In lecture Ted used models to explain how there is so much CO2 ppm in classrooms we are basically toxifying kids. There are many contributors to C02 levels rising in this world including light spectrum, volcanic activity, and largely human impacts.

Textbook:

1. What did you learn? Greenhouse gases are molecules made of three or possibly more atoms bonded together. Gases move quickly and collide with other molecules in the atmosphere. This causes greenhouse gas molecules to vibrate and have an asymmetrical shape.

2. What was the most helpful? The video about carbon dioxide and the greenhouse effect helped me visualize the true gas problem our Earth has. Visuals are a great way for anyone to understand what is going on.

3. What do you need more information on? The way carbon dioxide is measured (ppm) is sort of confusing. Is there a good visual for this?

1. What questions, comments, or concerns do you have? None.

Week 1: Earth Moon System

Week 1: Earth Moon System 1. What did you do in lab today? This week in lab we answered a handful of questions related to common misconceptions of how humans interpret the seasons, Moon, Earth, etc. We then got to model in groups how we thought the Moon and Earth rotated along with discussing how the Solar and Lunar Eclipse. 2. What was the big question? Three questions discussed in class along with my answers prior to whole class discussion: 1. How the phases of the moon occur? (The Moon covers the sun while it rotates around Earth.) 2. What causes the seasons? (The seasons are caused by how far away the Earth is from the Sun.)  3. What causes a lunar eclipse? (A line of the Sun, Moon, and Earth, but I'm unsure it what order.) 3. What did you learn in Thursday's discussion? I was not present in Thursday lecture due to an away volleyball game, but I did receive notes from Isabelle Sneath!  All the planets are on the same geometric plane, EXCEPT Pluto, therefore Pluto is not a ...

Week 4: Scale Model Solar System

 Week 4: Scale Model Solar System 1. What did you do in lab today? In lab we conducted an experiment to model the first four planets of our Solar System. We were able to use whatever was available to us in the classroom (lab space). The goal was to make it to scale in means of size and distance. My table group decided to start with our Sun being 500mm. From then on Mercury was 1.748mm, Venus was 4.349mm, Earth was 4.577mm, Mars was 2.428mm, and the Moon was 1.247mm. We ended up going from the science lab room down to the PLC at the West side of North Lindquist.  2. What was the big question? The big question presented at the beginning of lab was "Why is the sight of a full moon phases startling in the middle of the day?". A full moon during daylight happens when the moon and sun are positioned on opposite sides of the Earth. In this phase, the moon usually rises right as the sun sets and disappears as the sun comes up. This makes its presence during the day feel sort of out o...

Week 2: Space - The Final Frontier

Week 2: Space - The Final Frontier 1. What did you do in lab today? There was no lab as it was a holiday. 2. What was the big question? The four big questions we explored in lecture included how the moon was measured, who has gone to the moon, and what is the future of space travel. 3. What did you learn in Thursdays discussion? In lecture I learned that a  Greek astronomer Eratosthenes, 240 B.C.E found that the size of the Earth. He started with the knowledge that a circle is 360 degrees. He measured the angle of his shadow to be able to find the distance and multiply it by 50 and that is the length of the Earth. Ted talked about how y ou can easily do this in a classroom when you team up with other schools aka collaboration!! It allows students to see math and science in a real world context. Textbook: 1. What did you learn? I learned that James Van Allen created the radiation detecter that was in the Explorer 1 Satellite. His discovery of magnetic radiation belts around ou...
