Place all bags in a safe place. Be sure not to open any of the bags. Return to the bags of bread each day and observe how they change (expect to see results after about a week when using baker's bread). The Science Behind It. Certain pieces of bread develop mold faster or in larger amounts than others Procedure. Sprinkle water on the slice of bread. Put the bread in the plastic bag and zip it. Use the tape to secure it further. Write today's date on the tape with the marker. Leave the bag undisturbed for 7 days in a warm place outside the house. Track the growth of the mold by checking the sample every day The results of the experiment will remind you that you should always wash your hands. Aside from the control piece, the soap and water slice was the only piece of bread that had no mold on it. Even hand sanitizer, which we might think as a substitute for hand washing, showed evidence of mold
The purpose of this experiment was to see whether different temperatures in different kitchen environments would affect the rate of fungal growth (bread mould) on bread. It was essential that I had a tight control in my variables and that I didn't change a lot of my variables because it might affect my results dramatically Bread mold experiment I think the mold will grow naturally on the bread with water sprinkled because molds do not contain chlorophyll unlike the other normal green plants and mold needs moisture, dark place to be able to germinate and it is really hard for mold to grow on a dry surface such as normal bread as it does not contain moisture To grow, mold and other microorganisms need a few things, namely a source of food and a source of water. Because paper bags let so much air through, there wasn't enough moisture for mold to grow. But in plastic, moisture is sealed in and mold forms more quickly. The results. Wonder Bread . 11 ingredients; Theoretical shelf life: 7 day Experiment Steps. Now let's take a look at the steps needed for this experiment, one point at a time: 1. Take your plastic bag and label each as sample 1 - 4 on the bag in the upper right hand corner effects of mold. will conduct an experiment where they will Figure 2. Moldy bread. What are the health impacts of mold? Spores from mold growth, while natural, can also pose health risks. Some people, with or without allergies, are very sensitive to mold or may become sensitive to mold from single or repeated exposure
The idea here is that the more natural the bread, the more that bread mold is going to grow on it. I can't wait to see the results of your experiment, although I have some suspicions what the results will be :D That's why we refrigerate our homemade bread. Jennifer. on June 29, 2011 The fourth day of the experiment, each slice of bread was blow dried with a hair dryer for five seconds to create even faster results. For seven days, once a day, the mold was measured to observe its growth. The results of the Moldy Bread Experiment were that the Non-Organic rye bread was the fastest and quickest to mold Hypothesis The Hypothesis of this experiment is that bread mold will lie dormant in temperatures below 32 degrees and thrive in warmer temperatures. This hypothesis was based off of a statement made on the Mold Blogger website. 4. Process of Data Collection As predicted, mold spores are dormant in cooler temperatures 8. Keep a careful note of your results for each slice of bread for the entire duration of the experiment. You can even take pictures or draw the slices if you want to be really scientific! 9. Average the results for sample types A, B and C. 10. Once you have finished, throw out all of the bags without opening them
Mold spores are everywhere just waiting for the right environment to grow and multiply in. But what is the best environment for them? Is it cold or warm? Sunny or dark? This bread mold experiment will help your child find out, while developing important hypothesis-making and experiment-designing skills Moldy bread shows kids the importance of washing their hands. A teacher and behavioral specialist showed children the importance of washing their hands by using bread and mold in a science experiment Idaho teacher Jaralee Annice Metcalf showed her students what happens to bread that's been touched with dirty hands. https://bit.ly/2M0rN2f Subscribe: https:..
Bread 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. Most of us know that food seems to become moldy more quickly in the summer than in the winter when it is. The Effects of Moisture on the Mold Growth in a slice of bread. Purpose: This lab was an investigation on how moisture contributed to the mold growth in a slice of bread. Hypothesis: If the level of moisture in the bread increases , then the mold growth will intensify , since mold feeds off of moisture Introduction Mold is a microscopic organism Bread mold experiment for kids is a hassle-free fun activity that involves the least amount of risk.

We are attempting to answer this question by doing a bread mold experiment. We started out by baking two loaves of rye bread and two loaves of wheat bread. We put one loaf of each in a cooler, chilled with ice. And the other two loaves in a cabinet at room temperature. We will check the bread every school day and take pictures to display the. With DoughLab (or the equivalent components from the store), you can design your own delicious bread experiments and learn about yeast! Before you start, here's the skinny on saccharomyces: Yeast,a single-celled fungus that belongs to the same kingdom as mushrooms,is one of the most common microbes in the world.In the presence of oxygen, this fungus munches up sugars and produces carbon.
Results: The results of the experiment are that almost all the Wonder Bread slices have no visible mold, except for the sample labeled coffee, which grew mold that covered about 30% of the slice of bread. All samples of the bakery bread exposed mold. Conclusion: My hypothesis was correct because I predicted that the bakery bread sample labeled coffee would grow mold sooner than the others. or vegetables. Describe the mold(s) that appeared on the bread products. Extensions Repeat the experiment, and change the variables. 1. Place some bread samples in the dark, and expose other identical pieces in the light. 2. Place some bread samples in a cool place (refrigera-tor), and expose other identical samples in a warm place. 3 The mold colonies have ended up on the bread either from landing on the bread from the air, or as a result of being collected from the bench in the process of wiping. The difference in the quantity and types of mold present show that wiping the bread on the bench results in far greater mold growth as well as diversity However, what you got are still results. As the other expert suggested, it is still an indication on how effective preservatives are. He also suggested another experiment that could be achieved in between now and the due date of the project. I would add another suggestion: I noticed that organic bread tends to mold much faster than regular bread
. While mold spores aren't a virus or bacteria (they're actually fungi!), they are what we use in this experiment to show us just how dirty our hands can become throughout the day. According to the CDC, mold is everywhere, even in the air and on common area. Over the course of the experiment (1-2 weeks) you will start to see some seriously gross results. The bread that you handled with dirty hands should mold first and the rate of mold growth will be rapid. In some cases, by the end of the experiment the bread that was touched with dirty hands will be unrecognizable We chose this experiment for our science class because we had been learning about decaying leaves and toxic mold and flu season was approaching, Jaralee Metcalf told Bored Panda. We decided it would be a cool experiment to learn about germs by using moldy white bread! Together, they put five slices of bread in separate bags The bags were left hanging for just a few days before varying degrees of mold started to form on each piece of bread, in a result that Metcalf called disgusting after sharing the experiment on.
Further, some fungi can use carbohydrate sources (such as those from wood) for energy that most bacteria cannot use. In this experiment, you will determine which factors encourage mold (filamentous fungi) growth on pieces of bread and apples. Add 120 mL of water to a saucepan or large microwaveable bowl and mix in Â½ cup of sugar Plants with chlorophyll have the ability to absorb energy from the sun and convert it as nutrition. Otherwise, mold needs to absorb the nutrition from other plants, animals, or medium. Bread is one of the perfect media for mold to grow. Mold does not grow well in direct sun light. If bread is stored in a cupboard, plastic container, or a bread. The choice of using bread was chosen because it is common food found in kitchen. The dependent variable is the mold growth. To prepare for this experiment, I will put two Â½ inch slices of wheat and white bread exposed to the air, and another two Â½ inch slice of wheat and white bread contained in an airtight plastic bag. Then, after every week. Purchasing bread with few preservatives usually means loaves of bread tend to have a shorter shelf life. Unfortunately, however savory these loaves can be, they usually become moldy, which results in us accidentally taking bites from slices of moldy bread. Worry not, as eating these fuzzy green mold spots on slices of bread will cause us no harm
Use the following scale to assess the extent of mold growth. 0 = none. 1 = little/some (1-25%) 2 = moderate (26-50%) 3 = heavy (51-75%) 4 = extensive (76-100%) Record your results in Table 1. Do not open the bags when you are finished with the experiment. This will disperse mold spores and contaminate your work/living area Science experiments with mold show how different environmental conditions like temperature, type of food medium or surface, and moisture, are conducive for mold growth.

The independent variable for the experiment is light and the dependent variable is bread mold reproduction. A control is a test in which the independent variable is kept constant in order to measure changes in the dependent variable
Because most bread sold in grocery stores and to schools needs to have a long shelf life, it includes preservatives. The experiment took place over 3-4 weeks because of this (although the mold started forming on some of the slices in just a couple of days!). Here's what slice #1 - the one rubbed on the Chromebook - looked like FLU CAUSES MORE THAN 300 MINNESOTA MIDDLE SCHOOL STUDENTS TO CALL OUT SICK. A month later, the results were in. The control remained mold-less, while the piece touched with clean hands appeared.
an ANOVA comparing the different brands of bread to each other. Results We found that there is a statistically significant difference in mold growth between organic bread and non-organic bread, the p value was 0.27 (figure 1). Less mold grew on the organic bread than the non-organic bread. We found no statistically significant difference Methods and Results. Now, this bread mold is known to be able to survive in both types of mediums. It can survive in the minimal media by turning what is available into those other vital building.
A teacher and behavioral specialist showed children the importance of washing their hands by using bread and mold in a science experiment.
