1/14/15 Lab 1: Biological Life at AU

I. Purpose: The purpose of today's lab was to observe and record characteristics of an assigned transect. My assigned transect was group 3: Tall Bushes. I recorded macroscopic observations of abiotic and biotic components in my transect. Then my group made a Hay Infusion Culture from materials gathered from our niche.

II. Materials and Methods:

· 20 x 20 meter transect to study

· Use a sterile 50 mL conical tube to gather materials such as soil and vegetation from transect

· Place 10-12 grams of gathered materials into a large jar

· Add 500 mLs of deerpark water to the jar

· Add 0.1 gm of dried milk into the jar and screw on lid

· Mix contents gently for 10 seconds

· Place the jar in designated lab section area with the jar labeled and lid off

III. Data and Observations:

The abiotic components inside the transect included:

· Light

· Water/snow

· Concrete

· A metal lamp post

· Dirt

· Rocks

The biotic components inside the transect included:

· Grass

· Shrub

· Bushes

IV. Conclusions

This transect is located north of the Battelle-Tompkins at American University. This is an aerial-view diagram of my transect labeled with it's abiotic and biotic components:
