====Summary====                   
{{$demo.summary}}



====Procedure====  
  -Label two plastic bags “Wet Bread” and “Dry Bread.”
  -Place 10 drops of water on one slice of bread and seal it inside the “Wet Bread” bag.
  -Place a dry slice into the “Dry Bread” bag and seal it.
  -Store both bags in a warm, dark location such as a cupboard.
  -Predict which slice will mold faster and record your hypothesis.
  -Check the bags daily for 7–10 days, recording observations in a notebook or chart.
  -Do not open the bags; observe mold growth through the plastic.
  -At the end of the experiment, compare results and draw conclusions.

====Variations====
  *Test different types of bread (white, whole wheat, gluten-free).
  *Vary the amount of water added (5, 10, 20 drops).
  *Compare growth in warm vs. cold conditions.
  *Compare bread stored in sunlight vs. darkness.
  *Leave one slice unsealed to test the effect of air exposure.



====Safety Precautions====
  *Never open the bags once mold growth has started.
  *Do not touch or inhale mold spores; always keep samples sealed.
  *Dispose of sealed bags in the trash after the experiment is complete.
  *Wash hands thoroughly after handling materials.




====Questions to Consider====
  *Which slice of bread molded first? Why? (Moist bread molds faster because fungi need moisture to grow.)
  *What conditions help mold grow best? (Warmth, moisture, air exposure.)
  *Why shouldn’t moldy bread be eaten? (Mold produces spores and toxins that can be harmful.)
  *What role do fungi play in ecosystems? (They decompose organic matter, recycling nutrients.)
  *How does this experiment model how food spoils at home? (Moist, warm conditions encourage microbial growth.)
