Molds grow on foods that are wet. Molds can jump from one food to another.
|
|
|
We wanted to find out what kinds of molds affect food.
|
|
|
- jars
- tape
- water
- strawberry
- bread
- pineapple
- orange
- potato chips
|
|
|
Get clean jars. Get some types of foods and cut them very small. Dip the food in water. Then put the wet food in a jar. Seal jar with masking tape or another strong tape. Then record dates you put the food in the jar and name your specimens.

Maxıs conclusion:
In conclusion I found out that citrus foods such
as fresh oranges and pineapple grow greenish
mold, and it grew fast. Strawberries grow fuzzy
white stuff, but it took a long time to grow.
When you have a piece of mold with a strawberry
it jumps fast. As for a long time the
strawberry sat on its juice and faded. The
cooked zucchini grew a fuzzy kind of mold. It
also grew fast. As for the uncooked zucchini,
it just on the bottom of the jar. The Hostess
cupcake did grow some mold. Whenever we put a
piece of mold separated from a piece of food.
It jumped to the food.
Andrewıs Conclusion:
My conclusion proved that our hypothesis was
wrong. Some mold grew on dry foods and some
specimens that were wet didnıt grow mold. My
specimens showed none of them having mold
jumping from one mold to another. For my
specimens I didnıt put a drip of a water as Max
did put submerged most of my specimens.
