for the post below .
Th description should read as bottom photo to the one highest.

(sorry for inconveniences)

photo of experiment 1

The following photos display mould. From the photo above follow left , top and right.
The bread pieces display different levels of fungi. The photo with the bread unaffected by mould was sprayed with 20% bleach concentration. To the left of that photo, it showed indications of mould spores which was conducted under the 5% bleach concentration at day 6 or 7. The first photo on the top left corner displays mould spores forming around the bread. The last photo shows the bread which has reached its final stages of degrading it was sprayed with 0% bleach concentration. As seen the bread piece size is far from what the original amount looks like.
This shows that bleach concentrations with higher amounts of bleach does stop mould from growing . The two controls can be compared with the two different bread pieces and its observations.

method of experiemnt

1. Loaf of white bread was bought from the supermarket
2.The loaf was cut into 10 square pieces (3 x 3cm)
3.The 4 pieces of bread was labelled as experiment 1
4. The other 4 pieces of bread was labelled as experiment 2
5.Each bread was labelled 0%,5%,10%,20% in experiment 1
6.Repeat steps for experiment 2
7.Plastic container lids were prepared (8 lids)
8.The lids were divided in 2 groups
9.The first four lids were labelled as experiment 1
10. The other four lids were labelled as experiment 2
11. All the bread pieces were placed onto each lid according to its experiment number
12. All four empty sprayers were labelled ;0%,5%,10%,20%
13.From the measuring cup , 20ml of water was measured out and poured into sprayer bottle 0%
14.From the measuring cup, 1ml of bleach was poured into sprayer 5%
15.The measuring cup was rinsed and wiped clean
16.From the measuring cup 19ml of water was poured into sprayer 5%
17.From the measuring cup of 2ml of bleach was poured into sprayer 10%
18.The measuring cup was rinsed
19.A total of 18ml of water was measured from the measuring cup and poured into sprayer 10%
20.A total of 16ml of water was poured into sprayer bottle 20%
21.A total of 4ml of bleach was poured into sprayer bottle 20%
22.The bread pieces from experiment 1&2 with the 0% label was sprayed with the 0% sprayer
23.Repeat step 22 to the other bread pieces and their assigned sprayers
24.Spray assigned bread pieces with solutions three times a day for 7 days
25.Place all bread pieces on lids in a damp spot, preferably away from sunlight
26.Repeat step 15 three times a week
27.The bread pieces were observed everyday for 7 continuous days
28.The mould should not be moved or shaken during experiment
29.A table was drawn up to record any descriptions of mould growths or changes
30.Observations of the mould was recorded during the week everyday
31.Each assigned bread piece was thoroughly observed
32.Observations were recorded onto a table
33.The whole method should be repeated one more time to obtain more accurate results
(the experiment can be repeated using 4 bread pieces ,4 number of lids, half the number of chemicals. 3.5ml of chemical & 35ml of water

method

All of the 3 experiments have been completed
and finalized.

experiment conducted'

the first experiment
has been conducted and results are in; since i changed from A
different
experiment to this one i had to hurry.

My first set of data did support the hypothesis
water will stimulate mould growth but bleach will kill and stop all mould growth.
Over time , the mould did respond to the bleach concentrations. It had stopped
growing, but the bleach sprayed and treated with water encouraged mould growth.

mouldy,.

previously i spent my other weeks
preparing a little test.
My test was between detergent, dettol, bleach and floor cleaning substance.
My results have finalized that bleach was the strongest on most dry
molds and fungi but not on wet molds.

Finishing final experiments on the effects of bleach on mould.

I had 2 hypothesis together; one with water
i want to find out if water will have any effect on the mould
so i decided to put them together.

hypothesis: water will stimulate mould growth but bleach will kill and stop all mould growth.

final.the effect of bleach on mould.

TO make a better experiment;
ive decided to use one dependent variable. Mould.
There were far too many dependet variables in my other plans.

TESTING THE EFFECT on mould.
with bleach.

toodles.

changed to the better;

It has been decided that
instead of using so many different variables
i am using one type of fungi.
mould on bread .
More then a handful of bread has
been in a bin outside for 4 days now.
Tomorrow i shall start extracting the bread pieces out.

To see which detergent or household agent effectively
kills mould the fastest. From a couple of hours to a few days.

EXPERIMENTS

fungi types such as foot fungus can be get ridden of using
household liquids .
Vinegar, Tea Tree Oil, Listerine, and Alcohol
helps stunt the fungi spores.
This can be related to the fungi and household experiment.

• This is a photo of the fungi/moss/mould arranged in a column. The column is of the detergent & was taken before any drops of detergent was dropped.
  

method : experiment 1.

This experiment uses 2 types of fungi- penicillium & fusarium
& moss and mould

Which household liquid will kill fungi,moss & mould most effectively?
equipment-
tweezers
1 marker
1 container lid
1 eyedropper
1 measuring cup
4 types of fungi in 4 different portions
2.5ml of washing detergent for dishes
2.5ml of bleach
2.5ml of advanced floor cleaning liquid
2.5ml of dettol antiseptic

MEHTOD:
1. Gather the following equipment
2. Set out equipment , placing container lid on a flat surface
3. Using tweezers place each portion of penicillium onto the lid
4. Repeat step 3 to the fusarium, moss & mould portions
5. Label each column using the marker
6. Measure the washing detergent with the measuring cup(2.5ml)
7.Fill the eyedropper with washing detergent and squeeze onto the first column.
8. Repeat steps 6-8 to the other household liquids
9. Allow 15 mins and record observations
10. Allow another 15 mins and record any changes

-Penicillium fungi

-Fusarium fungi

MOSS & MOULD

Results:

During each 15minute intervals (there was 3 intervals in total)
The fungi types had shown the most discoloration and affect.
3 days later, spores were thriving off the fungi types. Around the edges of the
fungi, spores were still growing out of the fungi, hence dettol antiseptic isnt the
best option . Some fungus bits were harder then the rest .
The moss had completely dried out.
The mould had no effect, but did not thrive or grow.

photos of experiment 1 -dettol antiseptic

diagram 1(on left):
The four different types of fungi and moss are collected. Instead of a petri dish a clean cup lid was used instead.

diagram 2(second ):
2ml of Dettol was dropped on the fungi and moss. The photo was taken 15 mins after the dettol had been dropped. The penicillium fungi had been affected the most. The mould had no effect. The other fungi type started to show discolouration.

experiment 1.

Experiment 1:
equipment-
* eye dropper
*dettol
*container lid
*portion of mould
*portion of moss
*portion of fusarium(mould found on rotten bread)
* portion of penicillium mould (found on rotten bread)


independent variable : dettol antiseptic
dettol solution contains-
-chloroxylenol

2ml of dettol antiseptic

POINTS TO CONSIDER:

Theory is that antibiotics kill the 'good' bacteria
which also prevents fungal growth.
This is why antibiotics are never given to fungal infections.
Although this is a theory, i can prove this theory right
by testing it on a measured growth of fungi.

Fungi are eukaryotic ( similar to human cells)
the mechanism for destroying the cells are different.

It is a known fact that antifungals kill all types of fungi .
E.g. yeasts to dermatophytes ( athletes foot)
So, it would be pointless to include antifungal cream or drops to
the dependent variable as it kill fungi the fastest.

independent variables: antibacterial soap
dettol
antibiotic drops
washing detergent
all independent variables are measured the same

dependent variables: mould on bread
algae growing in shower/ shower head
rotting fruit

aim: To see which chemical antibacterial brand will kill fungi the fastest

yay idea came back to life~

so im doing the antibacteria on petri dishes and how to Compare the effect of antibiotics on gram-positive and gram-negative bacteria.
IT SHALL BE FUN.

yay thought of idea ..



..it left me now :(
