1.27.15 Missing a lot of information. Need to address all red text in manual and organize lab into: Purpose, Materials, Data & Observations, Conclusions. Need to include picture of transect and describe Hay Infusion set-up. Transect is 20ft by 20ft there is a typo in the manual. SK

January 15th, 2015: Biological Life at AU

Purpose: In this lab, we observed evolution by looking at Chlamydomonas, Gonium, and Volvox. These organisms are all members of the Volvocine Line. Number of cells, colony size, specialization, motility, and sexual reproduction were all taken into account.

Materials: Slides with organisms, microscope, paper, pen for procedure one. Pencil, paper, jar, soil collection from transect, dried milk, and deerpark water for procedure two.

Data & Observations: Procedure 1: The Volvocine Line Observe Chlamydomonas, Gonium, and Volvox for certain characteristics in order to see similarities and differences.

Procedure 2: Observing a Niche at AU Observe the ecology at American by looking at a 20x20 ft transect. The transect observed had both abiotic and biotic components. Abiotic components in this transect were soil, snow, a fork, wood chips, and cement. Biotic components in this transect were grass, flower buds, leaves, flower bushes, and a spider.

After samples were taken from our transect, we made a Hay Infusion Culture. To do this, dried milk and deerpark water were added to our soil that we collected. The Hay Infusion Culture sat in the lab for a week without a lid. ALS

Conclusions: Evolution could be explained by looking at the different lines of Volvocines.
