1. My Cheese Experiment By: Kristin Ewing

2. 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.

3. 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.

4. 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

5. Materials American cheese (square shaped) Swiss cheese (square shaped) 2 sandwich bags Notebook Pen or pencil

6. 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.

7. Control Variables Bags cheese

8. 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

9. 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

10. Data Swiss cheeseAmerican cheese Day 1. turning a darker yellowDay 1. slightly getting moist Day 2.thin and greasyDay 2. moist Day 3. nothing Day 4. turning greenDay 4. nothing Day 5. the green is spreadingDay 5. moist Day 6. nothing Day 7. almost blackDay 7. nothing

11. 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.

12. 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?
