I took the sample pond water from the library pond (Central Michigan University), thinking well during mock rock this year I want to know really what I am swimming in. So I took a jar then scooped it up from the muskiest part of the pond. After collecting the sample we placed the sample in a glass jar in the Biology lab at Mid Michigan Community College by a window and then it was sealed with oxygen holes. We would be checking on the sample once a week for lasting six weeks, just incase we …show more content…
As the oxygen levels increased, the water looked and smelled cleaner, and more life was visible.”(Example) My pond water did the exact opposite, the odor and the color changed for the worse. However things that I found in the Central Michigan University Library was very disturbing, I found large single celled organisms called Protozoan and these guys can create some huge problems with people if they ingest any of the water during their little dip into the CMU Library pond. “Protozoan’s are typically large single celled organisms and are found mainly in aquatic environments. These organisms if ingested may cause gastrointestinal disease, dysentery and ulcerations of the liver and intestines.” (Storm water) Reading over the stuff and things that are swimming around in the pond makes me wary on every participating in Homecoming week again. I was expecting more things swimming around during my microscope observations but I think that CMU chlorinates the pond so things are killed off, or at least most things are killed by the chlorine. I also was shocked to find out that the pH level raised over time, I thought it would be more consistent then it was. Another thing that I was confused about was that my pond water did the exact opposite thing everyone else’s did. My water became darker and cloudier with a more intense smell. I have no idea why that happened and I would like to
