Transcript of What was our question?

Materials
The bread on the counter molded faster and had the most mold. By the end of the experiment, the bread in the fridge had only a few splotches of mold and the bread on the counter was basically completely covered in mold.
What were the results?
In conclusion...
What was our question?
Our hypothesis was correct and we discovered that bread left on the counter grows mold quicker than bread left in the fridge. They were pretty close with the amount of mold grown on them. What we could do differently next time is not swap the breads by accident. We did that one time.
2 Breads
2 Zip lock bags
Water
Fridge
Counter
Spray Bottle
Camera
Pen

Microscope
Paper
In due time, which bread stays fresher in the counter or in the fridge?
"Bread" Coming Of Age By Patrick Quinn, Edgar Mendoza, Pablo Nolasco
We predict that the bread on the counter will stale quicker because the bread in the counter is exposed to more dirt particles that will go through the bag and microorganisms that also can go through the bag.
Hypothesis
1. You first get one ounce of water and place it in the spray bottle
2. Put on gloves
3. Spray the water on the slice of bread and place it in the zip lock bag
4. Put the bread in the ziploc bag on the counter
5. Repeat steps one and three
6. Now place that bread in the fridge
7. In due time, every day use the camera to take a picture of the two breads
8. With the pen and paper record the levels of freshness and percentage of mold on the breads

Procedure

Our discussion was that the bread on the counter took less time to mold than the bread in the fridge. The bread in the fridge probably grew les mold because it wasn't exposed to many things like the bread on the counter. The bread on the counter was exposed to many dirt particles and other microorganisms.
Our discussion
Background
Bread consists of special ingredients that make it fluffy and edible. Bread has yeast, flour dough, and many oils that keep it fresh for a few weeks. If it was unattended for a few days, the yeast that is in the bread turns white and begins to decompose. Now if the bread was to be sprayed with water, that will make the bread moist and will begin to decompose quicker. Dust particles and microorganisms in the air help mold grow on the bread. I researched which ingredients in bread keep it fresh and which substances grow on bread from the surrounding air. For what ingredients keep bread fresher, people who use humectants, water attracting ingredients keep the bread fresher longer. Ingredients such as salt and sugar work as water attracting ingredients in bread keep it fresher for a longer period of time. www.Sci-toys.com/ingredients/bread.html. Mold grows on bread from the surrounding air, because in due time dust and microorganisms in the air get on the bread creating mold.
