Project Title: Effect of Bleach on Mold
Awards:Honourable Mention for my school Science Fair Project
Hardware tools used:camera
Source of the idea:Internet
Special skills used to build the project:(html)
Project Abstract: In this experiment I wanted to show
how much bleach is needed to kill mold.
I was suprised to see that bleach is so strong
and it stops the mold growth even at concentrations
less than 5%.I used bread to grow mold in petri dishes
with agar and treated the bread pieces with different
concentrations of bleach every other day.To make the
experiment work, I chose to use agar because it is a good
base to grow small organisims such as bacteria and mold.
The concentrations of bleach I used were 0, 1, 2, 5, 10,and 20%.
I had two sets of petri dishes for each concentration to make
sure the experiment worked. In the end mold grew only at 0% bleach
and some grew on 1 and 2%this experiment shows how bleach can
be harmful to the enviornment.
