Hi, this is Lilly and Claire!
First, we got a piece of bread. We had to split the bread into three parts. Then, we rubbed one of the pieces on a desk, one on a shoe, and the last on our tongue. Each of us had to hypothesize which piece of bread we thought would have the most mold based off information we researched.
After that, we put it in a petri dish. The petri dish was split into three equal parts. It was clear so we could see the mold as it grew. We had to label it afterward so we knew which bread piece was which. We put tape on the sides so it would be extra tight. Once we had mold growing we didn’t want take the chance that it would open! Yuck!
Last we put it in a big black container under a desk. We would check the mold twice a week. It took a couple of weeks for the mold to become visible. Once it did we were amazed at the different colors we saw!
These are most of the colors we saw: yellow, black and blue-green. We also saw white fluffy looking mold. Some people didn’t have any mold at all…my group! Bummer! We must be too clean.
Here are some facts about mold…
There are five basic types of mold that grow on bread. The most common mold is penicillium.
used as flavoring for foods such as blue cheese and soy sauce.
What do you think would happen to our world if we didn’t have mold?
