The main focus of this experiment is to observe the difference in mold growth between

slices of bread that were handled with dirty hands and with clean hands. As a control test there

was one slice of bread that was not handled by human hands and was only touched with clean

Germs were first discovered by Louis Pasteur. In 1850, Pasteur first started investigating

why beer at a factory was turning sour. In his work to determine the cause, he put a sample of

the beer under a microscope. This is when he found thousands of microorganisms that was

living in the beer. These microorganisms are what we call germs. He went on to continue to

study different liquids and the presence of germs in them. Pasteur then came to the belief …show more content…

Joseph Lister knew of Pasteur’s work and took it a step further. Lister researched how

there was a connection between post-operative death and infection and how clean the hospital

conditions were. Most of the steps he came up with for use in surgical rooms to prevent the

spread of germs and infection are still used today.

FACTUAL SUMMARY

Mold is a fungus that can be found anywhere. Mold grows best in conditions where there

is moisture and warmth. Just like germs, mold spores are easily spread. Mold can be spread by
