On Friday, October 22nd, one beta food pellet was added to my micro aquarium. Bellow I have included additional information about the food pellet. I observed much more activity this week than I did last week. There were all kinds of organisms swimming around. In addition to the organisms identified last week, I also found several amoeba this week. There were also many organisms that I could not identify because they would not stay still long enough. I managed to take pictures of some amoebas as well as another euglenoid.

October 21st - Week 1 Observation
Today, I observed my micro aquarium for the first time since the initial set up and took several pictures of the various organisms I observed. At first, I had trouble locating anything, but as I became more familiar with the equipment I was using, I was able to locate several different organisms.
The first thing I spotted was a Rotifer. I was able to identify this as a Rotifer because of the transparent, wheel like structure of the organism. Throughout my observation, I spotted several more Rotifers. The second thing I came across was a Gastrotrichs. This one had a clear "slug like" appearance. However, the characteristic that led to the identification of this organism was its split tail. The last organism that I was able to identify was a Euglenoid. This one was easy to identify because of its green body and its red eye spot. I observed several other organisms, but I was unable to identify any of them. Some of them moved too fast to get a good look at and others were just too small.

Microaquarium 1st entry
On the first day of our term project we set up our micro aquariums. First, I obtained the necessary materials from the instructor. I then added soil and water from source #5 (Meads Quarry Island Home Ave.). Next, I added plants A and B (to supply oxygen) to my micro aquarium. There was not much activity during the first observation. I only saw one organism under the microscope. It was moving by spinning its body in a spiral motion.
