Bread Mold Experiment By: Stephanie Westover

PURPOSE
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 …show more content…

Controlling for those 2 factors while maintaining proper and consistent measurement procedures should provide a repeatable and reliable understanding of how temperature variations affect mold growth.
Because the researcher will be measuring mold growth on food and because there is rarely if ever an acceptable level of mold growth on food, absolute precision in measurement is not necessary. This experiment is designed to measure the relative growth of mold across temperatures, not the exact level of mold growth on an individual piece. Therefore, measurement in units of 16th of an inch using a standard fractional rule should suffice. A fractional ruler was used because it easier to utilize in measuring the mold than any other measuring device.

Controlled variables:
-Standard ruler: 6” stainless steel ruler with graduations to the 32nd of an inch.
-Type of bread purchased: Western Family wheat bread.
-Date the bread was purchased: All bread samples will be from the same loaf purchased the day the experiment begins.
-Size of the bread piece: Each sample is one slice.
-Sterility: Each sample will placed in a sealed bag, preventing the introduction of extraneous bacteria.
-Moisture: Each sample will placed in a sealed bag, preventing the introduction of moisture.
-Light: Each bag will be exposed to the same amount of light for the same duration each day.
-Size of the “Zip Lock” baggies: Each bag will be the same size.
-Testing Actions that were used:
