  • Purpose/Description:

This experiment was about examining biological life on American university's campus. Also examined, Chlamydomonas, Gonium, and Volvox under a microscope.

Materials and Methods: Transect: Draw a picture of the Aerial diagram of the transect on campus. Collect samples from the assigned area with an zip-lock bag. observe area and take note of all the biotic and abiotic components in the transect note details about the transect. Hay infusion: Put 10 to 12 grams of the sample from transect into a plastic jar. Pour 500mLs of deep park water into the jar. Put 0.1 grams of dried milk in the jar then close the jar and shake it well for 10 seconds. label the jar and place in a safe place. Volvocine Line: Pipette a one sample of the Volvox, Chlamydomonas, and Gonium. Place each sample on its own slide and examine the the slides separately Record data to fill out Volvocine line chart and sketch what each organism looks like Data: the Transect that was assigned was a small creek on the north side of campus, behind McDowell Hall. The creek is rocks(abiotic) covered with Moss(Biotic) and fallen tree branches(abiotic). There are about 23 trees(Biotic) and small plants(Biotic) that were in the transect. there were also some dead leaves(abiotic) mixed into the soil(abiotic), also there were some plastic bottles(abiotic). Did not see any animals or organisms in the transect at the time. Conclusion: There would have been more biotic components in the transect, if the weather was warmer but because of the cold weather many of the organisms are underground or somewhere else warmer.
