January 26, 2015: Lab 1: Biological Life at AU In this lab the main objectives were to 1, understand how natural selection drives the evolution of different species and 2, to make careful observations about the characteristics of a niche. The Purpose of this Lab was to familiarize ourselves with microorganisms and our transects. This would help our understanding of Evolution by observing the surrounding environment. We also gathered materials for the follow-up lab a week from now. Methods and Materials: In the first procedure we examined microorganisms with our microscopes. We observed three organisms ranging from smallest to largest called: • Chlamydomas • Gonium • Volvox These organisms are in the Volvocine Line. The Procedure for dealing with our transect was: • Observe the 20 by 20 meter transect • Know the number of the transect • Use a sterile 50 ml conical tube for soil and vegetation The Procedure for the Hay Infusion Culture: • Place 10 to 12 grams of the soil/ground water into the jar • Add 0.1 grams of dried milk • Mix for 10 seconds • Remove lid and place on the table • Label jar well Data and Observations: [1] [2] [3] Abiotic Factors: • Lampost • Sidewalk • Snow/water • Soil • Rocks • Sprinkler Biotic Factors: • Tall bushes • Leaves • Plants • Trees • Short bushes • Woodchips Conclusions and future predictions: I believe that the abiotic factors and biotic factors of our transect might change in the coming weeks. I think that the hay infusion jar will have many microorganism we can observe through the microscope.
