Question

Mr. Arnold's 5th grade science class did an experiment to see if mold would grow better on moist bread or on dry bread. Each lab group was given two pieces of bread. They were to add 20 mL of water to one piece of bread and no water to the other piece of bread. They were also to keep both pieces of bread in a cool, dark place and to make daily observations of the bread. However, Keisha and Sam did not read the lab procedure carefully and they put 20 mL of water on one piece of bread and 40 mL of water on the other piece of bread.
At the conclusion of the experiment, mold had grown on both pieces of their bread. On which piece of bread did mold grow better?
a Mold grew better on the moist bread.
b Mold grew better on the bread kept in the dark.
c Mold grew better on the dry bread.
d We don't know since Keisha and Sam added water to both pieces of bread.

Answer 1

IT WOULD GROW BETTER ON MOIST BREAD BECAUSE IF IT IS DRIED IT IS HARDER FOR IT TO FORM AND IF IT IS MOIST IT WILL GET MOLD ON IT FASTER
