4. Objectives: to take bacterial swabs from places around Ironwood Ridge.
to inoculate (swab) Petri dish with bacterial culture and monitor growth
to count bacterial colonies
to find out where bacteria are the most numerous
to determine what kind of environmental conditions influence bacterial growth

5. Materials: 1 Petri dish with agar per group (of 3) cotton Q-tips
Masking Tape (parafilm)
 Grease pencil (sharpie)
 Incubator

6. Bottom of the Petri dish!!!!

I’ll divide the divide the dish into 4 equal parts with a sharpie & number 1-4.
Write your groups’ initials and period on a tiny piece of masking tape and stick to your Petri dish (DO NOT OPEN IT YET!)

(… and why are bacteria around anyway?
Think about:
“We are 90-99% DNA” (from TED TALK)
Where do bread, yogurt and cheese come from?
How many of the 3 Domains on Earth are bacterial (prokaryotic)?
What about decomposition…. Think about everything you have
learned – Are bacteria mostly good? Bad? Both?
