We started today by creating our micro aquariums by using small glass containers a couple centimeters thick and filled them with a water type, each person chose the type they wished to use. My water was number 5--which came from a pond near Meads Quarry in Knox county, TN (picture far left). Then we put in two different plants: plant A- an algae (darker green plant closer to the left in the aquarium) and plant B-an insect eating aquatic plant (stringy mass of light green closer to the right). After putting the plants in the aquarium and filling it up with the water used previously, we took a look at the aquarium using our microscopes. We got a close up look of what was in the aquariums, including what was in the sediment from the water we used that settled at the bottom. Here are my observations.

There appear to be a large amount of microorganisms in the sediment of the water. One type was a small, brown, translucent, ovular shaped organism that moved rapidly in the sediment. Another was a larger ovular shaped organism with one-two tails that swam more in the open water but close to the sediment. A third is shown in the top right of my notes, there were many of them, they were transparent and quick moving, they also liked to hide from the light in the sediment, so finding them is difficult. An orange, transparent worm-like organism sifted through the sediment, apparently eating eat. Finally, a much larger organism that is similar to the previous, but MUCH larger, on the 10 objective it took up approximately half the view.
