experiment

okay i've decided on an experiment:

'Do different brands of bread take different periods of time to become mouldy?'

I will be using the brands WonderWhite, Sunbeam and Sunblest, all white bread. The percentafes of yeast used and preservatives present of each brand will be noted.

Independent variable: the time taken for different brands of bread to mould.
Dependent variable: the amount/type of mould produced.
Controlled variables: the conditions in which the bread moulds in; same brands and types of bread are used each time.

Aim: to investigate the rate at which different brands of bread become mouldy.
Hypothesis: the brand of bread with less water and less preservatives will mould faster.
Method:
1. Take a slice of each type of bread and seal them up in separate bags.
2. Place them in the same conditions for them to become mouldy.
3. Check the rate of mould production everyday using a microscope and record results.
4. After 2-3 weeks, take out the slices of bread and compare the production of mould.

an idea..finally :)

omg haha i finally got an idea. what about doing an experiment on whether different types of bread (eg white, wholemeal, wholegrain, multigrain, etc) produce different types of mould, ms zhang? your approval before i start?

i've done some research on what mould is and different types of mould. according to http://ezinearticles.com/?Bread-Mold&id=405845:

• Bread mold is a kind of fungus that is commonly found on bread surfaces.
• Bread mold is found in different types, species, shapes, and colors. Some of the common bread molds are Penicillium, Aspergillus, Rhizopus, Monascus, and Fusarium.

also, this website suggested an experiment which could be performed to see bread mould:

'If you are interested to see bread mold you can perform a small experiment with bread. You can take a slice of bread and moisten it slightly. Then keep the bread for two or three days in a place where there is no chance of the moisture content drying up. You will see some mold growth on the surfaces.'

i will probably be doing this first to get the mould, then using a microscope to examine the type of mould, and recording the results. any variables i have to consider? or any ideas ?

sigh..

it's been a while since i posted on here
i just read the list of project ideas and i'm thinking...
something to do with food ?
i don't know..
i'll think about it today and hopefully will have decided something tmrw
see you laters
