HELP!!!
okays i am having the same trouble as Jessica with combining all of my results into one or two tables. so im going to leave it for now and start my report :(
say MOLD!
here are some pictures i took actually all the pictures i took, i kinda forgot about it
i forgot what each of them were and when they were taken so these are just for your enjoyment.

results! results finally!
okays, well im juggling between masterchef, Breaking the Magician's Code (which is sooooo good) and Big Bang Theory and SRP. yeah. just great but it's okay, there all kinda related to science so im doing my work :D Apart from my little break i have results.
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

Later i'll post another table with a more organised results.
i like to move it move it
yes i need to move it into light speed asap. i have calculated that i have around 4 hours left of today to do as much as i can. i am doing all my results now and tabulating it. don't worry everyone, i just had vitamin water and i am PUMPED!
i also realised that forgot to mention some of the risks involving the experiment. here are some of the things that could have killed me:
i also realised that forgot to mention some of the risks involving the experiment. here are some of the things that could have killed me:
- ingesting the mould is dangerous as it is a bacteria so i have to always where gloves if handling with mould and to keep it away from the eating table. i used a closed box to make sure that the mould woudn't contaminate other areas of the house
- sharp objects were used such as scissors and needed to use carefully
EXPERIMENTT
i started the experiment on Wednesday the 2nd of June, i changed the method a bit before i started, here's is what i did
1. the materials were collected:
i thought i will mention this i kinda stole my grandpa's box of zip lock bags, the bag of cotton swabs, the box of gloves and i borrowed the cup. the ruler, marker and scissors are mine. the dropper i got from the chemistry kit box that i put in the background, which i asked my mum to buy when i was young but i never did any of the experiments (maybe when i finish the srp i should do some of them). please ignore the toothpick container thing.
2. i realised that i couldn't really cut 10x10x2cm squares so i decided to cut 8x8x2cm squares,
the depth of the slices were roughly the same. what i did was, i used the crust that no one likes and i ruled the lines and i cut a sample. i used this sample as a guide to cut the rest of the slices. 10 with preservatives and 10 without.
3. Each zip lock bag was labelled accordingly
4. 5 slices
with preservatives where each put in the
'Preserv clean' zip lock bags and 5 slices of bread without preservatives where each put into the 'Non-preserv' clean' zip lock bags.
5. using the cotton swab, swab some dust on the center (on one side)of each 
of the 5 remaining bread slices with preservatives. Then using the dropper, 5 drops of water were dropped spread out around (on one side) on the slice of bread. place each slice in the 'preserve dust' zip- locked bags.
6. Repeat step 5 with the bread slices without preservatives.
7. 2 boxes were obtained. one labelled 'clean' the other 'dust'.
the zip lock bags labelled with 'preserv clean' and 'non-preserv clean' were placed in the 'clean' box. The other bags were placed in the 'dust' box.
8. the boxes were put side by side in a dark covered spot.

it's getting serious!
I've got a scarf, hobo gloves, thick woolly socks, leg warmers and a glass of water . i plan to lock myself to the computer all day. I AM GOING TO DO SOME SERIOUS STUFF.
okay today i have a long list of things i need to do like A LOT. i plan to finish uploading the information on my experiment, the results and the tables and graphs, AND to finish my report which will require some more research.
TIME TO GET TO WORK!! oh and i need a beanie
Also i would also like to thank the Queen. You are my hero. THANK YOU SOOO MUCH!
I WISH YOU A VERY HAPPY BIRTHDAY!! and eternal happiness.
