My Cheese Experiment
By: Kristin Ewing
Big question
• My big question is will American or Swiss
cheese will mold faster? I want to know this
because of I think it would be cool to see if
American cheese will last longer or shorter
than the Swiss cheese would.
Hypothesis
• My hypothesis is that the American cheese
will mold faster than the Swiss cheese. I think
this because the American cheese has more
moister than the American does. American
also has no holes in it like Swiss cheese does.

Materials

Notebook
Pen or pencil
Step by step instructions
• Step 1.Put both American and Swiss cheese into two
separate sandwich bags.
• Step 2.Place both bags on a smooth surface where it
won’t be disturbed or harmed.
• Step 3. report any observations you see over the next
week to see if American/Swiss cheese have molded.
• Step 4. Lastly in your notebook put down which
cheese has molded the most in one week.
Control
• Bags
Variables
cheese
Observations for Swiss cheese
• Day one-is getting moist in bag has changed to
a different color yellow
• Day 2-edges are getting soft. Looking very
greasy. Thin and getting darker.

Analysis of data
• My experiment did test my hypothesis. It
tested my hypothesis by the Swiss doing more
than the American cheese. What I would
change in this experiment would be that I
would put the American cheese in a container
without the lid.
Conclusion
• My hypothesis was wrong. The Swiss
cheese molded first.
• Some questions I have are- why didn’t the
American cheese mold? Why wouldn’t the
American cheese mold? Why did the Swiss
cheese mold faster than the American
cheese?
