Bread Mold Experiment By: Stephanie Westover

The purpose of this experiment will be to determine how temperature affects the growth of mold on wheat bread. The researchers choose this topic because she thinks it will be beneficial to find a way to keep food from molding. Determining how long bread can be stored before molding can help save money, prevent illness and preserve freshness. The question the researcher will attempt to answer is how freezing affects the rate of mold growth in wheat bread.
The information gathered in this experiment may be relevant to those individuals who contend with food borne molds at home, or professionally. Because the rate of mold growth can vary depending

This should ensure that the temperature of the bread sample will not fluctuate too far from the intended test temperature.
The Independent variable will be the temperature at which the bread is stored for the duration of the experiment.
The dependant variable will be the rate of mold growth during the ten days of observation
The researcher will measure the mold growth through the clear zip lock bag to ensure that no moisture, bacteria, or other foreign contaminants can influence mold growth. She will also leave the zip lock bags sealed to prevent the introduction of air to the samples. The researcher will measure the temperatures in each zone daily to ensure that the temperatures remain consistent. She will note any temperature fluctuations that may influence the mold growth and indicate the need for greater precision in temperature control. The researcher will ensure the samples are subjected to light only at the times the measurements are recorded.

My hypothesis is that bread mold when in a freezing temperature will grow at a slower rate than it will at a warm temperature.

MATERIALS USED 1. Three slices of whole wheat bread 2. Three Ziploc baggies 3. one ruler 4. freezer set to 23 degrees Fahrenheit bag A 5. refrigerator set to 41 degrees Fahrenheit bag B 6. room set at 65 bag C


These are the procedures that I followed.
1. Buy whole wheat bread
