1/25/15 Purpose: In this lab, we are creating a culture in order to examine the forms of life that are present around the school. Each lab group was given a different transect of a different wildlife area around the school. We observed the living and non-living components that make up a biological niche. My group’s transect resembled a marshy/ swamp sort of land, because it was right by a water drain. I hypothesize that the types of organisms we will observe will be found commonly around areas of water and mossy life. Materials: • A wildlife transect found somewhere on the grounds of AU • Paper • Pencil • 50 ml conical tube • 500 mls water • .1 g of dried milk • Medium sized plastic jar Methods: 1. Go out to assigned transect and observe the biotic and abiotic substance found there 2. Draw an aerial view of the transect 3. Describe the location, and topography of the transect 4. In the conical tube collect 50% soil from the area, and 50% vegetation from the area 5. Back in the lab, weigh out 10-12 grams of the collected soil/vegetation, and place it in the jar 6. Add 500 mls of water to the jar with the sample 7. Finally add the dried milk to the water and the sample in the jar 8. Put the lid on the jar and gently mix for 10 seconds 9. Open the jar and place it somewhere safe in the lab Data and Observations: The transect of my group was on the north eastern side of campus, in the front of the Kogod building. It is supposed to have the characteristics of a marshy/ swamp land, because it is located by a water drain. Most of the plants found in the small garden were dead for the winter, but there was still green grass and moss present. Some of the biotic features that can be found in the transect are grass, moss, red cardinal flowers, cat tails, and straw plants. Some abiotic features that are there are rocks, snow, a metal sign, trash, and soil. The sample obtained for the culture consisted of soil, snow, moss, some leaves from the plants, grass, and some straw from the plant. Conclusion: Back at the lab, a hay infusion culture was made using the sample from the transect. It will incubate for a week, so that next week, the living organisms that are present in the transect will be observable under the microscope. This will demonstrate what sort of organisms grow in different environments around the school. [[Link title]] IR
