Bread Mould (Brilliant Biology Experiments)

You will need:

1. 8 fresh slices of bread (4 toasted and 4 untoasted)
2. 16 plastic zip-lock bags
3. Sterile gloves
4. Labels and pens
5. Spray water bottle
6. Liquid soap
7. Hand sanitizer

Would a soap or sanitizer stop the growth of moulds on bread? Find out with this experiment.

INSTRUCTIONS

1. Put on sterile gloves and cut 4 toasted and 4 untoasted slices in half.
2. Begin with the untoasted slices. Place the first in a zip-lock bag and seal it. Label it.
3. Place the second in a zip-lock bag without sealing it.
4. Very lightly spray water on the next 2 pieces of the untoasted bread. Place them in separate zip-lock bags, sealing only one.
5. Spray 2 pieces of the untoasted bread, with the soapy water and place in separate bags, sealing only one.
6. Spray some hand sanitizer on the last 2 pieces. Place them in separate bags, sealing only one.
7. Repeat the entire process with the toasted bread the same way.
8. Place the labelled bags in a warm dry place undisturbed for a week.

RESULT

The bread sprayed with water/ soap and left unsealed will have grown moulds, but the bread in sealed bags will have less growth of moulds on them. The sealed bags with toasted bread will have even lesser moulds on it, because toasting the bread dries it out.
