=__Inside Bacteria v.s. Outside Bacteria__=

By: Michaela Douglas and Angela Kelley

 * **Growth** || None || None || None || None || Small || Medium || There is about twice as much growth in the outside sample ||
 * **Texture** || Normal || Normal || Normal || Thick layer on the surface || Same with a very small amount of fuzz || More fuzz seems to be growing in the outside sample || The inside samples have a smoother texture. The outside samples looks like fur ||
 * **Color** || White || White || White || Yellow || Yellow with small traces of green || More green in the outside samples. Transparent growth in the inside samples. || The inside samples have developed some yellowish bacteria growth. Most likely from skin cells. The outside has grown blusih green fuzz, maybe a mold. ||

====We're going to test the bacteria found on carpet. We chose carpet because it has a lot of bacteria. T he average homeowner's carpet harbors about 200,000 bacteria on every square inch, about 4,000 times as much as their toilet seat. **(carpeting, 2012)** Skin cells, food particles, and pollen can all feed bacteria living in carpeting. **(carpeting, 2012)** ====

==== We're going to test the bacteria found on the ground. 6,300 bacterial species may exist in a single gram of soil. **(soil, 2012)** Bacteria are the most numerous microorganisms in surface soil. **(soil, 2012)** ==== ==== **Procedure**: We're going to put 1/4 cup of milk in cups and swab the chosen destinations. We will grow them in the same room but in different cups, keeping the environment we grow them in the same. The milk serves as the food for the bacteria. The way our bacteria will react with the other bacteria in the milk may make the textures different from each other and the colors different. Milk supports the growth of a variety of bacteria **(Milk, 2012)**. There are five different bacteria in milk. **(Milk, 2012**) We will be checking the bacteria growth everyday and recording it for a week. ====

**Materials**:
 * cups (styrofoam)
 * q-tips
 * milk
 * 1/4 measuring cup
 * bacteria samples from outside and inside of a house

**Hypothesis**: If we take bacteria from the inside and the outside of a house then they will grow differently.
how often are you guys going to check the bacteria growth?(Overly) *How long a period of time will the bacteria be allowed to grow before you record the results? (Maggie Hatfield) What are you going to do about the tempature difference?(Morgan Gabbert) What will you do about the amount of light the bacteria get?(Howley 1/11/13))
