Lab 8 Climate Change

            I have chosen to use the “Environmental Protection Agency. Climate Change Basic Information” article.

            Part 1 Climate Change:

1)    I agree with everything said in this article. There is nothing in this article that I did not find to be untrue. I had not known actual numbers on climate change thought and learned them in this article. In the article they say “Earth's average temperature has risen by 1.5°F over the past century, and is projected to rise another 0.5 to 8.6°F over the next hundred years.” This to me surprised me.  I had thought when we started hearing about global warming it would be by a high number like 15 or 20 degrees. I had no idea it was just 1.5.

2)    Three places I could look if I had have any questions would be to look online at any reputable website. As in the ones we were provided for this lab. We also have our textbooks that we are using for the class. It is full of useful information that has been checked for accuracy. We could as an expert in Environmental biology such as a teacher or a scientist. We could even go to a library and look for books that pertain to the subject we wish to check.

3)    Yes having a background in environmental biology helps a lot. As I stated in question one without knowing anything about environmental biology I thought that when they said global warming it would be by some high number, like 15 or 20 degrees at least. Now with learning environmental biology I know that earth would most likely be destroyed at that rate and that all it takes is a very little change to change the whole earth’s environment. Still reading this article without having learned environmental biology I would have told myself what are we worrying about if global warming is only going to increase by 8.6 degrees Fahrenheit within the next 100 years. But thanks to this class I now know that if this happens it will set off a chain of events that will drastically change the way we live on earth.

Part 2 Biotic Communities

1.     I live in Rimrock Arizona which is “154.12 Arizona Upland Subdivision - Sonoran Desertscrub.”

Lab 6 field methods

Part 1 A Qualitative vs. Quantitative, Dimensional Analysis, and Growth

Qualitative –

1)      I see that the plants are the color green.

2)      There is brown dirt. It’s the brown that you see in the dirt after it has rained.

Quantitative –

1)      There are 12 green plants total.

2)      There are 4 planter boxes filled with the brown dirt.

Part 1 B Dimensional analysis

1)      A four-pound bass weighs how many grams?

There are 453.592 grams in a pound.

Equation 4 x 453.592 = 1814.368grams

Part 1 C Linear VS. Exponential Growth

1)      The graph for this question is attached as a photo.

2)      Question 1 – The most profitable is to earn a dollar with a 25% increase each day.

Question 2 – The six dollars a day while earning another six dollars each day at day 6 seamed the most profitable it was well above the pay of the one starting at only a dollar.

Part 2 B Measurements of Biodiversity

11) I choose this sight because it is our families garden.

Part I C

                                    Location                    N level/rating    P level /rating      K level/rating     pH level/rating

Sample A                         garden	N2 adequate	P2 adequate	K3 adequate	7.0 neutral
Sample B                         Lot across the street	N3 sufficient	P2 adequate	K2 adequate	6.5 slight acid

6)A) The nitrogen and phosphorous. They both contain phosphorous and oxygen.

B) We have to have soil to grow crops or anything. That we need to survive.

C) different soil types show the different regions it shows biodiversity because, one soil is in one place.

D) erosion – can carry sediments to new places.

Human interference – add different soils together changing the composition.

Genetically modified – we can engineer different types of soils.
