i will be conducting a second trial within the next few days
(it takes 15 days per trail, which means i AM putting an effort into these experiments)



only 3 more weeks till the final blog and report is due!!!
:(

(including this week), so technically, 16 days.. i think

Note to myself:
- find and include more info in blog!!
- cover sheet, report, booklet and something for crest award in 1 plastic sleeve when hand in (4 things)

REPORT NEEDS:
- abstract

- introduction
(includes hypotenuse and aim)
- method
(and materials)
- results

i just realised that i have no idea how to determine whether it's lighter or darker...
so if anyone else has ideas, it would be appreciated :)

i was looking over my notes the other day and i remembered the teacher saying something about the experimental design method (writing up the method in paragraph form)

so just in case we're to be marked on that,

METHOD:
A dozen uncooked eggs were collected, numbered and photographed separately for later uses. Eight plastic cups were collected, four of which were used to pour 140mls of listerine, 140ml of toothpaste solution (ratio of toothpaste to water 1:13), 140mls of salted water (ratio of salt to water 2:5), and 140mls of tap water. The first four eggs were then placed into the four plastic cups. The eggs were left to sit in the solvents for three days before carefully picking out and placing the eggs on a stand to air dry. The other four plastic cups from the eight collected, were then used to pour 140 mls of coke. when all four eggs had air dried, they were then placed inside the soda solution. the eggs were then left aside for 2 days. when the 2 days had expired, the eggs were gently picked out, lightly dried, then scrubbed clean. photographs were taken of the four eggs and compared to the previous photographs taken. observations and colour differences were then recorded in a table. the experiment was then repeated using 140 mls of lemonade then 140 mls of fanta instead of using 140 mls of coke.

how i am obtaining the results:
as you should know by now, if you have been following the blog, my results are based on colour. this may affect my results greatly, so for a more accurate measure, instead of using a colour chart like these (shown below), on the eggs




i'll be determining the colour difference using the 'colour picker' tool in the paint program, using the photographs i took.



this tool will tell me the exact colours of the eggs in a particular spot. because i took the pictures uniformly (using no flash, eggs seated in exact same spot every time, camera seated in exact same spot every time), picking the spot to tell the colour difference would be quite simple. i only need to find the exact width and length of each picture and press the button. this will give me the hue, sat and lum (but because i have no idea what those terms really mean, i'm going to use the 'red, green and blue' side)

the NEW table:

NB: process for determining the colour difference:

step 1: set the layout as 'show rulers and gridlines'

step 2: collect the 'before' and 'after' photo for egg 1
step 3: paste them onto paint, making sure that they are aligned

step 4: using the 'colour picker' tool, set and right click on the 300 x 200 margin
this colour should be saved to "color 1"
click on "edit colors" and record the 'red, green and blue' numbers

step 5: using the 'colour picker' tool, set and left click on the 1000 x 200 margin
this colour should be saved to "color 2"
click on "edit colors" and record the 'red, green and blue' numbers

step 6: record the results in the table

step 7: complete steps 2-6 for the remaining eggs
