Transcript of Bread Mould Experiment

By: Jordan Fielding Bread Mould Experiment The purpose of the experiment is to find out how the amount of moisture affects the growth of mould on bread. Purpose Hypothesis My hypothesis is that the wet piece of bread will grow mould first because it has the most moisture and mould needs moisture to grow. We took 3 pieces of bread, 1 dry (toasted), one wet (water), 1 normal and left them to see which kind of bread would grow mould first and how much mould each kind would grow. What We Did Procedure First, we write our names on each of the 3 bags. Then we put a piece of wet bread, dry toasted bread, and a piece of wet bread into the 3 separate bags. After that we seal up the bags and label them. Then finally, we watch! Materials We needed:

- toaster
- 3 plastic bags
- 3 pieces of bread
- electricity (for the toaster)
- water
- labels
- marker
- measuring spoons
- recording log Unfortunately we only had 6 days of observation. This was because the bread was getting smelly and weird. Observation Circle
(here) oO Observation Circle Oo Day 1 Since it was the day that we started the experiments,
there was no change, nothing at all. Day 2 No changes to normal and dry pieces,
but wet has grown green mould on one
side of the bread. Day 3 No change to dry or normal bread but a wet has 5 1/2 cm of mould and some touching the crust. Day 4 No change for dry and normal bread but wet bread has 7 cm of yellow, white, and green mould. Day 5 No change to normal and dry mould but lots of
mould on both sides of wet bread. About 8 cm
long of mould. There were lots of colours like
black, green, white, and yellow mould. Day 6 Still no mould on final day for dry and normal. Same amount of mould for wet as Day 5. White, yellow, green, and black mould. There is a yellow line of mould across the bread 5 cm long. Conclusion In conclusion my hypothesis was right and the wet bread grew the most (and only) mould. I can logically assume that the more moisture the bread has, the more mould it will grow. This was a fair test because each of the bread pieces had equal time to grow. The End
