Bread Mold and Storage Conditions
Easy
What keeps bread from going moldy the longest? You place five slices of bread in different spots:
- A dark, damp area with a few drops of water added
- A room at normal conditions
- Under direct sunlight
- Sealed inside an airtight plastic bag
- Inside a refrigerator
Each day you check the slices with a magnifying glass for signs of mold. The damp, dark slice grows mold first. The refrigerated slice stays mold-free the longest.
Hypothesis
The hypothesis is that bread mold will grow more quickly in warm and damp environments.
Method & Materials
You will prepare 5 slices of bread in different environments and observe the rate of growth of bread mold.
You will need 5 slices of bread, some water, an airtight plastic bag, a refrigerator, and a magnifying glass.
Results
The results showed that the bread kept in the dark and damp place was the first to exhibit signs of mold. The bread kept in the refrigerator took the longest for the mold to appear. This proves that bread mold will grow more quickly in warm and damp environments.
Why do this project?
This science project is interesting because it shows how quickly bread mold can grow in different environments.
Also Consider
Experiment variations include baking the bread at high temperatures before starting the experiment, and using different types of food like biscuits or cooked rice.
