Bread Mold Experiment Essay - 2022 Words

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 â€Å"Zip Lock† baggies: Each bag will be the same size. -Testing Actions that were used:Show MoreRelatedTesting The Conditions Of Black Bread Mold Growth1054 Words   |  5 PagesConditions of Black Bread Mold Growth II.

Both hand soap and hand sanitizer kill off the germs and bacteria that can cause infections and diseases. Which one works best? The purpose of this experiment is to show which is more effective, hand soap or hand sanitizer (Bjornsson). To prove this, Bjornsson writes up a lab using the growth of bread mold to help identify the results of both products (Bjornsson). I believe that hand soap works better than hand sanitizers because doctors remind us that we should wash our handsRead MoreMold Experiment1325 Words   |  6 PagesBread Mold Experiment Mold is something that we often take for granted, as something that makes us have to throw the bread away or the cheese smell bad. Mold is, in fact, a fascinating organism which has had many different uses over the years and our lives would not be the same without it.

It is a process for experimentation which is used to explore and answer questions. When scientists cannot directly experiment (dinosaurs digesting food) the scientific method is slightly altered and therefore cannot fully answer their hypothesis. Throughout the experiment scientists may re-do some parts to gain backup evidence, they may also use others evidence to help along with their own work. Scientists follow the method to enable them toRead MoreSurely YouRe Joking Mr. FeynmanÂ… Essay1151 Words   |  5 Pagesactually tried the Coke bottle e xperiment with my roommate.
