Week 2

Observations:

Without the microscope I was able to see very active clear organisms moving around the tank. Also, some of the Wolfia was turning brown.

Under the microscope I observed multiple Cyclops Copepods moving around the tank a great deal. These did not stay in one part of the tank, but moved through all layers.

I also observed two Ostracods, or seed shrimp, in two different stages of life. One had already shed its shell which was visible at the bottom of the tank. The Ostracods stayed in the Wolfia at the bottom of the tank and one appeared to be consuming the Wolfia.

The moss is still green and seems to be doing well.

Week 1

Set up:
I began by obtaining an empty aquarium and labeling it with the appropriate colored dots (red, green, and green).
I chose to use water #5 and, using a pipete, filled the aquarium 1/3 full with water from the bottom of the sample, 1/3 with water from the middle, and 1/3 with water from the top.
I then placed bits of moss C into the tank.
Observations:
The tank contained a good bit of green Wolfia visible to the naked eye.
Under the microscope, I observed one Copepod Cyclops. It remained stationary but was vibrating a great deal. At one point some brown stuff shot out the back of it.
