METHOD:
aim:
to determine what type of solution best protects egg shells from acids

hypothesis:
the solution that contains the most amount of sodium, will protect egg shells from acids, the best

risk assessment:
method:
1. collect a dozen eggs (uncooked), 140mls of coke, lemonade and fanta, containers (8) and three lots of 140mls of Listerine, toothpaste and water in ratio 1:13 , salted water in ratio 2:5 and tap water
2. take a picture of the first 4 eggs(for colour reference- at the end)- note remember which egg is which
3. fill up 4 containers of one 'lot' of solvents (Listerine, toothpaste compound, salt water and tap water)
4. soak the eggs (4) in the solvents for 3 days
5. pick up the eggs slowly, placing them on a stand to dry. note: do not wipe them dry
6. place the eggs in separate containers of coke and leave aside for 2 day
7. pick up the eggs and, with a towel,lightly dry them, then scrub clean.
8. observe the eggs- what is the colour difference compared to the matching photo taken in step 2
9. record the results in a table
10. repeat steps 2-9 for the rest of the eggs,this time placing them in lemonade and fanta instead of coke

results:

conclusion:
--



note:
~ i think my aim and hypothesis makes sense...
might have to do a bit more research
~ i couldn't really assess more risks because my experiment isn't dangerous. so i just have one :)
~ because i have written a method in blog 5 without a clear idea as to the amount of liquids used or the amount of days the eggs can be left in the containers, i have changed a few things from that method to make the one above- the amounts of liquids (volume), ratios and days have been changed to conduct this experiment more easily and to suit the containers and how much (grams/ milligrams) of the materials i have bought
~ with my results, i found a colour wheel/chart thing that shows a variety of colours and different shades in that form. so i will be using that to differentiate the colour before and after the experiment. whether the colour change is lighter or darker depends on whether the number on the colour wheel/chart is greater than or less than the previous one.
~ the conclusion (obviously) has not been written up yet because the experiment has not yet been conducted.

...hope that all made sense


now that that's all done, i shall start my experiment
if any problems shall arise, I'll be sure to let you know
wish me luck
..i hope this all goes well and that i don't make any mistakes :)
