Chlorine: Fertileizer or killer of mold?

[Imammstcnerd]

For my research project I chose to see how different amounts of chlorine in the growing medium of paper effect the growth of the mold pennicilium.

Along with the chlorine we stored the experiment in incubators set to different temperatures 21, 27, 35 degrees Celsius.

I expected the highest amount of growth to occur on the tray kept at 35C with no chlorine but instead the tray with a lot of chlorine and stored at 21C had the msot growth

maybe the chlorine did not affect the mold at all(which is in itself strange) and the temperature was the only decisive factor. my guess is molds should grow best at room temperature

[Imammstcnerd]

I think the chlorine did have an effect because the one with a lot of chlorine didn't grow until 3 days later than the ones with it. the one with chlorine grew a lot in a smaller period of time.

ok we're scientific people and we must build up our views according to the results

it's clear now that temperature is the main decisive factor >>> not the only, but the main one

I guess that chlorine hasn't that omprtant effect on the mold

and it's clear from you experiment

________________

repeat ur work with different concentrations and fix the temperature

then fix the concentration of cholrine and change the temperature

and I think you will find the correct answer

i like your suggjestions and i'd try them out but this was my freshmen research project for high school and it had to be a two factor design of experiment. (DOE)

p.s. I'm sorry if it sounded like i had an attitude in my previous post

Nice words buddy
