Final method, i swear.

Okay, since ms Zhang said that my other method was too primary school level, which I agree, I have come up with my final method, hopefully. The aim and hypothesis will be stated in my introduction.

Materials:
  • 4 slices of non-preservative bread (I used Baker's Delight bread)
  • 4 cotton balls
  • 4 sealable bags
  • Rice vinegar
  • White vinegar
  • Brown vinegar
  • Magnifying glass
  • Dropper
  • Face mask

Method:

  1. Wet the 4 cotton balls with water.
  2. Seal each slice of bread in a separate sealable bag and dab one area of the bread with a cotton ball until it is moist. Leave the bag in a dark area until mould begins to grow.
  3. Put on face mask.
  4. Draw white vinegar into the dropper.
  5. Open a little slit of the sealablebag and place a few drops of vinegar onto the bread mould.
  6. Wash the dropper afterwards.
  7. Observe any changes to the mould over a period of time when changes start happening to the mould.
  8. Record your observations.
  9. Repeat steps 4-8 with brown and rice vinegar.

And I have started my experiment tonight! I've put the slices of bread in the sealable bags and chucked them under my bed. Dark place ;)

I'll upload photos tomorrow. For now, night!
