i gave up organising the pictures and also click on the images for a clearer look. i guess you can call this my raw datasheet. well it's the one i used to record my results.
if your wondering how i worked out the percentages. well all i did was some vague mystical movements then BAM! MAGIC!!!. the secret is some calculator punching and i got the idea from a previous California science fair project(which i previously mentioned before :D http://www.usc.edu/CSSF/History/2006/Projects/J1305.pdf
what i did was i made this 1x1cm grid (shown below) and everytime i measured, i calculated how many and how much of the squares it took and i calculated the % covered in mould by dividing the amount of squares covered in mould with the total surface area of each slice (which i found varied a bit) and convert into a percentage.
and i also forgot to mention that i didn't have time to do a second trial but im going to count my trial with the dust and water as my second trial. hmmm i hope this works out
