Bread Mold Experiment

What makes mold grow? https://explorable.com/mold-bread-experiment Mold is a natural substance that kills germs and helps humans to live a longer and a healthier life. This substance isn't only used for one purpose but is also used in other medicines across the world to save millions of lives. Mold grows naturally in the environment and occurs in nearly every ecosystem in the world. There are many ways to test the ways of how mold grows such as temperature and this is what they use in this experiment. They use summer and winter as their different seasons of observation. The method they used in this source was that they put each piece of bread into different environments and see which bread mold occurred the fastest and how much of

They use winter and summer but these seasons in South Africa are different to other countries.
Only done by one person and no other further results by others have been commented.

Growth of Bread Mold: https://bcrc.bio.umass.edu/courses/spring2010/biol/biol312section3/content/growth-bread-mold-due-temperature This experiment also explains what mold is but goes into detail about specific conditions and temperatures mold needs to be grown at. Within this experiment they use different experiments and many samples of bread to make sure that their experiment will be accurate and will have a larger amount of results. This source does discuss its methods and materials used and it also discusses the results that have been extracted from the experiment itself. The experiment shows that greater temperatures such as 26.7'C will cause the mold to grow faster and spread quicker rather than being in a cold environment such as 2.2'C.

Validity:
This source has validity because it is very factual about mold itself and the different temperatures at which it will grow the fastest.

Reliability:
This source is reliable because it was done by a professor at the University of Massachusetts and was accompanied by two other

Day Five you do not see any changes on the white bread where as the whole wheat bread has started to form small amounts of the mold but not yet extremely visible. Day Seven you start to see small amounts of mold growing on the white bread but not yet enough to throw it away, where as the whole wheat has already gotten bread mold but at this point those small amounts are increasing there size and starting to spread and take over the surrounding area. On day Twelve you see that both breads have both gotten a nice amount of mold covering but the only difference is that the white bread mold has not spread on a larger area but has clumped together and started changing its colour from a green to a yellow-brown colour, where as the whole wheat bread has kept the green colour and it has spread more widely around the area of the
