Biology Experiments on Bread Mold

bread mold experiment observations

Meredith Juncker is a PhD candidate in Biochemistry and Molecular Biology at Louisiana State University Health Sciences Center. 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. The independent variable in this case would be the types of bread used since this is the variable the researcher changes to and controls in order to determine the experiments outcome. Spray the bread with water. Food in refrigerators seems to keep longer than food left out in the sun. Have you ever taken time to inquire of how to store bread? Most are not even conversant with how the experiment is conducted.

A few days la ter the three slices of bread will be observed and compared. Students ensure to breath on both pieces of bread. These spores are a constant part of our environment, but they rarely cause health problems. There are various species of bread molds. This time he sneezes into my elbow. Sample A 80 Degrees Fahrenheit c. Usually, one sees thread like structures on top of which there is a circular shape.

Important Note Please note that some people are allergic to mold; ask your doctor or parents. Mushrooms and toadstools are a type of fungi. Compare the specimens after two weeks. I chose to do my mold project on cheese and soda and titled it Cheesy Science With a Pinch of Fizz. How It Works What in the world causes mold to grow on products like bread? The amount of mold grown on the samples in ten days seems a good amount of time to let mold spores gather together. All types of soda were bought cold and fresh.

Label the bags with the bread types. At the end of each segment of the head you should be able to see small spores. While I am checking their work I have the student explain to me why it is important for us to wash our hands. Using the guidelines, make observations. At the end of the experiment this can take a few weeks , I glue the bottom part of the sheet into the students' science journal and have them draw what they observe and answer the questions.

There are usually plenty of student volunteers so I use the fair sticks to select a student. Samples are checked every day, for ten days, at the same time each day. Setting up accurate and effective experiments is a skill the students will need to develop so that they are able to test their own hypotheses. To begin, set up two bread specimens and two fruit samples. It is important that you observe them every alternate day without fail, and note down your observations in a table.

It's just a matter of time before the spores settle again. At the end of ten days the samples will be collected, photographed and measured. Maybe you could keep the temperature the same for all of the samples but use different types of bread. We will record the results in our science journals. You will glue this on the page next to your recording page. Even though many people will not take much care on how they store bread, there is a very high risk associated with eating moldy bread. Your final graph should resemble a line graph.

This way you can vary one element, and note down various observations of the mold growth. Table number two, you know what to do. This can be done with a sheet of graph paper and colored pens or on a computer. Prepare your specimens according to the guidelines. Complete observations as described in the guidelines. We recommend using soft bread that is preservative free, but many fruits or vegetables such as potatoes or oranges will also work. On the fifth day, the humid bread was 12.

Conclusion If white bread's freshness is affected by salt, darkness, humidity, cold temperature, or light, dry environments, then the humid environment will cause mold to grow the fastest because it is a nourishing environment where spores can develop. What Are They Doing On My Food? What are mold's favorite foods? Containers will be thoroughly cleaned. Don't forget to wash your hands! Write down whether you think there will be more or less mold for each condition at the end of the experiment. It also was spongy and appeared to absorb more coffee compared to the bakery bread. When the conditions are favorable, such as warm temperatures, shaded or dark places, and moisture, these spores will settle down and begin to feed on the bread. White, yellow, green, and black mould.

Ensure all the Ziploc bags remained sealed until disposal. The dependent variable would be when the mold started to grow. Put each bag in a spot where it will not be disturbed: one goes in the fridge, one on a shelf or table and one near a radiator, heat vent or other heat source. Hand wash and 1 dishwasher cycle with steam heat. Pour Sprite in container about ¼ filled and seal in a Ziploc bag.
