Methods

Specimen Collection: Not all water collection plates were used because they did not all contain water; 2 cement, 2 plastic; q-tips were used to collect the bio slude from the bottom of the collection plates; droppers and beakers were used to collect the dirty water from the plates; all samples were kept seperate to prevent cross contamination
Specimen Study: a dry and wet mount was created for each collection plate; dry mounts viewed at 100 magnification, wet mounts at 40 magnification; each group viewed a different collection plate's samples, and the number of different organisms was noted.
