What is the conclusion of bread mould investigation?
Conclusion. The conclusion is that when faced with all other factors constant, the temperature will have an effect on the growth of mold. It was shown that in temperatures of below 32 degrees farenheit no mold growth occured. However, at room temperature there was slight mold growth.
What is the purpose of bread experiment?
Purpose. The purpose of the experiment is to find out how the amount of moisture affects the growth of mould on bread.
What is the main hypothesis of the bread mold experiment?
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.
What is the observation of bread mould?
By looking at the hyphae under a microscope, you will be able to identify what kind of mold it is. Rhizopus feeds on starch or sugar, making it a common mold on bread. This type of mold may start off as white hair-like structures and eventually will form solid black spots.
What is the independent variable in making bread?
Independent Variables: Rise time. Temperature. Water content. Water type (distilled vs.
What causes mold growth on bread?
Mold grows on bread because spores land on it and begin to multiply. It can grow quickly on bread and start a colony.
What factors affect the growth of bread molds?
The major factors affecting growth of mould are nutrients, temperature, light, aeration, pH and water activity. Nutrient requirements for moulds may vary from mould to mould. Some moulds may thrive well on substrates with high sugar or salt content.
What is the independent variable in bread mold experiment?
The variables that are not changed are called controlled variables. The problem in this section concerns the effect of light on the reproduction of bread mold. The independent variable for the experiment is light and the dependent variable is bread mold reproduction.
How does mold play an important role in nature?
Molds play an important role in nature. They the speed up the process of natural decomposition by breaking down organic materials like leaves, wood and other plant debris. In other words, mold helps get rid of nature’s trash.
Why does the bread easily get molds dependent variable?
The dependent variable would be when the mold started to grow. This is a dependent variable because when the mold begins to grow depends on how much water or moisture is sprayed on the bread.
What makes mold grow faster?
Warmth. The last thing mold needs for an ideal environment is warmth. This just means temperatures above freezing, which is why you may see mold in your refrigerator but won’t see it in your freezer unless it’s not working. Mold grows fastest in temperatures above 60 degrees Fahrenheit.
What three conditions does bread mould need to grow?
1) Mold requires warm temperature for better growth. The temperature is in a range of 77 to 86 degree Celsius. 2) Mold needs high humidity or moisture condition for growth in size. 3) It also requires oxygen for quick growth and development.
Which variable can be manipulated in an experiment?
the independent variable
A manipulated variable is the independent variable in an experiment. It’s called “manipulated” because it’s the one you can change. In other words, you can decide ahead of time to increase it or decrease it.
What is the independent variable for bread?
In an experiment with moldy bread, a researcher might be trying to determine how much moisture it will take for a bread to go moldy. The independent variable would be how much water the researcher sprays on the bread. The amount of water is the independent variable because this is the variable the researcher controls.
What factors affect the growth of mold on bread?
How does mold benefit the environment?
What is the control variable in bread mold experiment?
The other variables for the experimental and control setup, such as the environmental conditions for the room where the boxes are placed—temperature and humidity—and the brand of the breads used must be kept the same. These are controlled variables.
How does mold start growing on bread?
Appearance. This is one of the most important ways to identify bread that may be contaminated by mold.
Is there a project on bread mold?
Mold facts for science projects. When doing your bread mold science fair project, here are some fun mold facts for kids to include: Mold is a type of fungus. Mold grows in the shape or multicellular filaments called hyphae. Mold grows from spores that float in the air. There are thousands of types of mold, some good and some bad.
Can You bake bread in a mold?
Nuts, bread, and even rice contain this type of mold. Oftentimes, the seeds and the upper surface of bread and nuts start to form a light discoloration. Even baked products like cookies and cakes can carry this mold, which can often be destroyed, once it is exposed to extremely high temperatures.
Which bread molds the fastest?
Acidity of Bread. The acidity or pH level of bread can help determine whether or not it will mold more quickly.
