Materials and Methods



A microaquarium was obtained with a stand and lid. It was coded with lab period information, table information, and seat position information using three color coded stickers and by wrinting individual initials on each sticker. A pipet was used to extract a small amount of muck from test container nine (individual's choice) and carefully squirted straight down into the microaquarium. Mostly water was then extracted from the same test container using a pipet and filling the microaquarium to about halfway. A square inch of two water plant species was then obtained and placed in opposite sides of the microaquarium. More water from the sample container was then retrieved and placed in the microaquarium up to about two millimeters from the top. A microscope was then used on ten times magnification to observe the contents of the microaquarium. This will be repeated once a week for five weeks. The microaquarium was then lided and put into storage.

Observations Week One

I first saw a tiny transparent. segmented worm that did not appear to move very much on a part of plant A. After scrolling across the microaquarium I came across a dark hairy oval within plant B, after looking a while in plant B I found many more of these objects. In the muck, Plant A, and plant B I found seven unicellular dark green algae organisms that appeared to move. The most fascinating find on the initial day was a extremely large, transparent yellow tinted worm that was very quick moving and agile. It appeared to be agitated by the light of the microscope and it also seemed extremely hungry, taking several bites of the muck within in a second for at least two minutes. After this amazing find I struggled to find anyting else other than a tail of a transperant blue tinted organism sticking out of the muck. This was all I saw of interest. Good Day.
