Brian's group project evaluation
I think this was a good project to do because it was very interesting. I liked going out and measuring the trees in the transect the most. I also liked finding out what kind of tree it was out in the woods. The third thing I liked about the project was actually finding out how much money in timber is on the hill. It was really hard doing the project by myself though. My parents in my group weren't at school or didn't help out much at all. So I had to do the whole thing in one night an that's the part I don't really like. Overall it was alright but I just wish I had more help on the project.

Brian's aerosol blog
Aerosols or particulates are fine particles in the air and
can either be solid or a liquid aerosol. They are formed from a wide variety of
natural and anthropocentric sources like biomass burning, incomplete combustion
like black carbon, soil dust and sea salts. These are not good for the climate
and can cause changes like an extreme precipitation change. We use aerosols
around the house every day that are not harmful, but other aerosols can really affect
our lives. If there are more aerosols on the clouds and are reflecting the suns
heat it can lead to world global cooling.

Brian Johnson's ozone blog
Oxygen, carbon
dioxide, and ozone are all beneficial and harmful. Human and animals need
oxygen to breathe but plants can die from too much oxygen. Plants need carbon
dioxide to live though. The ozone protects us from the sun’s harmful
ultraviolet rays but surface ozone can cause health problems. Surface ozone is
formed when (NOX) and (VOCs) from cars
and power plants are emitted. This is when nitrogen in the air Is burned from
cars or power plants and Volatile Organic Compounds and Oxides of Nitrogen are
released. The sun’s rays cooks them and
makes ground level ozone. Ozone can damage the lining of your lungs, aggravate
asthma, make it harder to breathe, and irritate your respiratory system.
