  1. Light and Moisture and its Affect on Muenster Cheese By, Brian Wheeler & Casey Gruttadauria

  2. Introduction • The purpose of this experiment is to see what environment mold grows better in, Light or Dark. And to see if mold grows better with more or less moisture. • We believe that the least growth will happen when mold is in light and does not have any water/moisture on it. • The cheese that is in the dark and has 15 drops of water on it we think will grow the most mold. • We think the cheese that has more water on it will grow more mold. Between a dark and light environment, the cheese in the darker environment will grow more mold.

  3. Experimental Design IV: Light and Moisture DV: Growth of mold

  4. The control of this experiment is the piece of muenster cheese that is in the light and that has no drops of water on it. Constants: The petri dish the cheese is placed in The type of cheese = muenster cheese The liquid used to moisten the cheese = water The temperature = room temperature The amount of time the cheese is in it’s environment in order to wait for mold growth Controls and Constants

  5. Procedure • Get eight pieces of muenster cheese • Get eight petri dishes • Label the petri dishes according to what the experiment calls for • Put the pieces of muenster cheese in the appropriate petri dishes • Drop the appropriate amount of water on each slice of muenster cheese varying on what the label on the petri dish says, remember to add drops on a regular basis • Put the pieces of muenster cheese in the petri dishes into plastic tubs • Place the plastic tubs with the petri dishes labeled “dark” in a cabinet and the plastic tubs with the petri dishes labeled “light” on the counter near the window • Take observations daily and take pictures whenever change in the muenster cheese has taken place

  28. Conclusion • After we did a mold transplant mold grew more on the cheese with more drops. • We discovered that the cheese in the dark environment also grew more mold. • The cheese without any drops of water which was in the light and dark did not grow any mold. • Our experiment clearly showed that mold grows better in a darker environment than a lighter environment, and the mold grows better with more moisture.
