Atmosphere notes

The Earth's atmosphere is 99% of atmospheric gasses, with water vapor being the largest in green house gasses. Other gasses in the atmosphere are nitrogen, oxygen, carbon dioxide, and other gasses. These gasses are invisible, unlike smog, the greenhouse effect is very important to the atmosphere, even more so of the ozone. Infared radiation is emitted to Earth's surface due to the warming of the atmosphere. The main gasses responsible for this are water vapor and carbon dioxide. Aerosols are also with the greenhouse effect. Pressure is important with the atmosphere pulling gasses towards the Earth. The higher the pressure, air is thinner, making it hard to breathe. 

Aerosols Conclusion (5th six weeks)

What effect do aerosols have on climate change?


It has a big role in climate balance. Studies suggest that increased aerosol loading may have changed the energy balance in the atmosphere and at the Earth's surface, and altered the global water cycle in ways that make the climate system more prone to precipitation.

 Aerosol effects on clouds can make large changes in precipitation patterns. It can change the regional and global circulation systems.

Aerosols suppress precipitation. Aerosols decrease the amount of solar radiation that reaches the land surface. That makes less heat available for evaporating water. It mostly shuts off precipitation almost completely. 

An example of the Urban Heat Island Effect is like how a city is a lot hotter in temperature than the urban areas around it. 

Aerosols

Aerosols are substances packaged under pressure with a gaseous propellant for release as a spray of fine particles.
Aerosols in the ozone layer come from products like hairspray, cans of paint, and other things like air conditioners.  Dust and sea salt are mainly the only two natural aerosols and they are the most abundant in the atmosphere, leaving man made aerosols with a smaller percentage in the atmosphere.  

Aerosols affect climate and weather because it does chemical changes in the atmosphere.  The particles mixed in with the ozone particles get hot from the sun and harmful rays, causing the aerosol particles to burn the ozone.  The burning of the ozone lead to a warmer climate because of allowing more UVB rays into the Earth’s atmosphere.  Aerosols is a leading factor to the harm of humans.  Aerosols is of the leading causes for the depletion of the ozone. 

Why Surface Ozone Should Be Studied

Surface Ozone Stuff

Surface Ozone affects every human, animal, and living organism on Earth. Ozone is very important. No oganism could survive on Earth without the ozone; there would be no oxygen and the huge amounts of UVB rays. Surface Ozone can threaten and enable life on Earth.
Without ozone, life on Earth would not be the way it is now. The man-made ozone that forms in the atmosphere is extremely toxic and corrosive.

The Ozone is a layer of different chemicals and oxygen in the stratosphere.

Surface Ozone affects health.
Surface Ozone can affect the way you breath and your respiratory region as a whole; it can make you cough, or have an itchy/uncomfortable throat.


Paints, cleaning supplies, photo copiers, and permanent markers contain VOCs. That is a big part that contributes harm to the atmosphere.

The ozone layer is made out of various gasses, most of which is created of various types of oxygen.  O₂ and O₃ are a large part to the ozone.  VOCs are also included.
Factors to protect the ozone are quite easy. The cut down of Fossil Fuels (like gasoline) and aerosols (like cans of hair spray) can save the deterioration of the ozone layer.

 

Group project evaluation

I thought working in groups was okay, but I much rather do independent work.
I feel like I did most of the work, and I think our group needed more communication.

3 things that went well

• We got the work done
• We all got along
• We worked together somewhat

3 things that could be improved

• more communication between group members
• equal work distributed among each person
• working together more

Measurements Procedure

• Found out what area we wanted to measure the trees in
• Taped off the area
• Went outside, and numbered the trees
• Then measured the trees in kilometers
• Figured out what types of trees they were
• Wrote down all our information on sheets
• Mr. Sharpe gave the circumferences of the trees
• Doing calculations 
• Measured forest area
• Finished calculating data

Scientific Method in Everyday life

~Revised


For one of my classes, I had to make a poster board for a project we were doing. I waited until the very last minute, the night before it was due, and I didn't have time to go and get a poster board, so I looked around my house for stuff I could use to make one.

1. Problem:
 I desperately needed a poster board for my project. As said above, I didn't have time since it was the night before to actually go out and buy one, so I had to find out how to make one.

2. Observation/Research:
I looked online to see what would be the best alternative to make paper thicker, without using cardboard. (I didn't have any of that, either.)

3. Hypothesis:
I told myself to try it out. I know it won't be perfect, but at least it would be something.

4. Experiment:
I found some old placemats that used to be on my dining room table that were not in use anymore, and they were pretty sturdy. I began by taking a couple of them, and taking a hot glue gun to make them stick together. They were pretty thick, so it was easy for the glue to work. Then, after letting them dry and making sure they wouldn't easily fall apart, I began gluing all the paper on. I had to do it in layers, so I put about four or five layers on each placemat.

5. Collect/Analyze Results:
It actually worked better than I thought it would! After it all dried, I could draw and write the appropriate stuff on it for my project.

6. Conclusion:
The next morning, I guess after it had COMPLETELY dried, there was still some dry glue on the sides. After scraping and peeling it off, I was very pleased with the outcome.

7. Communicating the Results:
I ended up doing it for class and got an A on the project! Just as I thought I was going to fail, I ended up doing great on it.
So, next time instead of freaking out because I couldn't go buy something, I realized maybe I should just look at my surroundings and see what I can make out of that.

Mr. Sharpe is really cool. I think I will like Earth Science.

I like to draw and I like my dog. I like him more than most people. He's probably my best friend. We like to eat lunchables together and watch The Office.

His name is Pik. He's awesome.
