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.

Interesting facts

• 1.place the cheese where no pets will harm it • 2.make sure bags are sealed completely• 3. don’t take cheese out of bags • 4.do not touch without gloves • 5.dont touch the bags while in the process of

the experiment• 6.write down all information

Materials

• American cheese (square shaped) • Swiss cheese (square shaped) • 2 sandwich bags • 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 Variables

• Bags 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.

• Day 3- nothing • Day 4-turning green • Day 5- the green is spreading • Day 6- nothing • Day seven almost black

Observations for American cheese

• Day 1-slightly getting moist • Day 2-moist• Day 3- nothing • Day 4-nothing• Day 5- moist • Day 6- nothing • Day 7- nothing

Day 5. the green is spreading Day 5. moist

Day 6. nothing Day 6. nothing

Day 7. almost black Day 7. nothing

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?
