*<u>Purpose</u>:  
To recognize how natural selection correlates with the evolution of different species and to formulate observations about my own sample niche. During this experiment, we looked to observe unicellular organisms and protists in our Hay Infusion culture. I think my Hay Infusion culture will contain evolutionary organisms in it’s soil.
For this lab, the purpose was to identify six organisms in our Hay Infusion culture by using the dichotomous key. My hypothesis from the previous lab was that my transect will be more abundant with protists than algae. During this lab, I will continue to test this hypothesis.

-Sample of my transect

-50 mL conical tube

-0.1 gm of dried milk

-Plastic Jar

-500 mLs of deerpark water

-Graduated cylinder

1. I observed and drew a picture of the area of my transect and recorded the abiotic and biotic properties of my transect.

2. I used a 50 mL conical tube to take a soil/vegetation sample of my transect.

3. Back in the lab, my group and I measured 500 mLs of deerpark water with a graduated cylinder. And placed it in the plastic jar.

4. Then, my group and I placed 12 grams of the transect sample and 0.1 gm of dried milk in the plastic jar.

5. We mixed the contents of our Hay Infusion Culture for 10 seconds and removed the lid of the jar.
