Bread Mold Experiment

Does bacteria on hands impact with mould growth

Introduction:
Mold is a part of the fungi family, it grows on almost anything with yeast on it if you leave it out for to long. Mold is often occurs on a yeast product like bread and this happens when the bread is in a warm moist conditions for a period of time like 4-10 days. mold on bread is common because bread provides a desirable source of nutrients for mold. These include the bacteria on the bread and the bread needs to moist and relatively warm and humid for it to take place. The mold that usually grows on bread includes Penicillium and Rhizopus. Mould is a form of fungi, fungi can be defined as any of a diverse group of organisms that live by decomposing and absorbing the host as they

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

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
In this experiment the conductor finds out that mould needs moisture thus needs to be included to conduct the experiment.
