“Post-Lab Questions”

“1. Which plate grew the most bacterial species (based on number of different colonies)? Was this a surprise? Why or why not?”

Click here to enter text.

“2. Was the control plate free of bacterial colonies? If yes, what does this mean for your experiment? If not, what could be the source of the contamination?”

“3. Did the airborne contamination plate contain any growth? Were any of the colonies similar in appearance to those found on the other plates? How does this plate demonstrate the need for following aseptic technique when culturing bacteria?”

“Post-Lab Questions”

“1. Did the colonies that grew on the transfer plates retain the same appearance from the initial plate? Why or why not?”

Click here to enter text.

“2. Were the colonies uniform in appearance on the transfer? What could account for any differences seen?”

Click here to enter text.

“3. Did growth occur through the depth of the stab tube? If not, what could account for the lack of bacterial growth?”

Click here to enter text.

“4. Why was it important to include a control plate and stab tube in this experiment? Did they serve as positive or negative controls?”
