Procedure II
When we first created the Hay Infusion Cultures Jars the water was clear, the plants were alive, and the smell was clean. After a week, when the observed the jars there was a stark transformation. The water was murky and dirty, the smell of the jar had a strong spoiled milk smell. A thin sludge film covered the top of the water in the jar, and a thick sediment of sludge settled at the bottom of the jar. The plants were no longer vibrant greens, they turned brown and dead with the water.
The organisms near vs away from the plant will be different because on a microscopic scale they are two different habitats therefore the species inhabiting the area will be different. For example, the species closer to the plant might be using the plant as a food source, whereas the species away from the plant may eat the denser sediment on the bottom of the jar.
We obtained our samples from the top film layer and from the bottom sediment sludge of the hay infusion cultures.

Characteristics of the transect: The transect is located at the Washington Seminary at American University. The transect is a circular plot of plant growth with trees growing out from it. Under the plant growth was rich damp soil which would be perfect conditions to support life, however a weed type growth of plants suffocate the area. Within the growth there were fallen leaves from the trees, sticks, and roots entangling the plants. A tennis ball lay on the outskirts of the circular plot, and a ball of aluminum foil was found in the center of the plot. Surrounding the transect is a grassy hill, the road, and stone park benches.
List of Abiotic and Biotic life:
Abiotic: Soil, Tennis Ball, Aluminum Foil, Park Benches
