Much more interesting

On Tuesday, I went to observe my microaquarium and had the chance to look at it under the microscope connected to the computer. I was much easier to locate organisms and I also was able to take pictures and videos that I have yet to post. I found a few organisms that we were able to identify. The first being an algae called "Eugiena Spyrogyra". It had a spot near the tip called the "eye spot" and stripes on its body called the "pellicles". It also had what is called a "flagellum". It is what propels the organism into motion (Forest, 1954). The second identified organism was a "Rotifer". It was by far the most interesting. It had a spinning head that would draw in water and would process the water through its body and shoot it out it's side. Another organism was a "Paranemia"; it is classified as a protozoa (Patterson, 1998). It had a very distinct flagellum that showed up quite nicely in pictures. There were also several other things that I was unable to identify. After I observed my microaquarium, I placed a food pellet in it as instructed.

Setting up the MicroAquarium

We began the lab by going over all the different types of water sources we had. I chose to use water source number 10. When we first looked through the microscope at the microaquarium I saw nothing moving. I only saw the soil and plants I had put in there. After looking a little while longer, I began to see little tiny speck floating around fairly quickly. Nothing special just very lightly colored specks. I thought that I had seen something larger float in front of the lens and then dodge into the soil, but I couldn't locate it after that. It should be interesting to see what shows up with the pictures we take.
