🎯
Aim
To observe the growth of bread mold (fungus) under different conditions of moisture and temperature, and conclude the optimal environment for fungal growth.
🧰
Apparatus
- Fresh bread slices
- Sealable clear plastic bags or petri dishes
- Water sprayer
- Magnifying glass or microscope
- Warm, dark cupboard
- Refrigerator
- Dry environment
🧪
Procedure
- Select the type of bread condition (Dry or Moistened with water).
- Choose the environmental condition: Warm/Dark, Room Temperature, or Cold (Fridge).
- Place the bread slice inside a simulated container and seal it.
- Advance the time day by day (Day 1 to 5+) to observe visible changes.
- Compare the growth rate across different setups to identify the optimal condition.
- Use the microscope view to observe fungal hyphae and sporangia.
