Observation 2
Without using a microscope, I noticed that the MicroAquarium had more debris floating at the top (mostly white colored). There also seemed to be less movement. Around Plant A I noticed more single-celled organisms than in the previous observation. There were about 20 in one field of view (under 10X). Around Plant B I saw a clear, fat worm and there was only 1 (it could be a midge larvae). Around the bottom layer I noticed a green amoeba-like blob and one stationary spiral worm. In the last observation, however, I saw a few moving spiraling worms. Even though I saw less movement in the MicroAquarium, I did not see any dead organisms in the bottom.

How were the worms moving? Were they round or flat?
