SCIENTIFIC METHOD

Mini Project

 

1. Problem Statement: Where can I find monerans

 

2. Hypothesis: Can single celled bacteria called monerans grow anywhere?

 

3. Materials: One potato sliced to get four half inch slices.

   Four baggies

   Three Q-tips

   Pan of boiling water

   Tongs to pick up the slices of potato

   Permanent Marker to mark the bags                      

 

4.Variable: (What could change the results of your findings?  Is there a possible error that could have been made?  Example: you sneezed into the bag before putting the potato in it.)

 

5. Control: one boiled potato piece  in a zip baggy and labeled.

 

6. Procedure: (How did you do run your experiment?)  Slice one potato into ½ inch slices. Place four into a pan of boiling water to kill any bacteria on the potato already.  After 2-3 minutes of boiling, use the tongs and place the potato in zip lock bags and close .  Label one potato in its bag the “control potato” and set it aside.  Choose another potato bag and a Q-tip, swab the Q-tip over a possible infected area, then use that Q-tip to swap the potato, zip the bag shut, and label the bag.  Repeat this process for the next two bags with potatoes.  Place the potato bags by a warm area or vent.
