k...Lakshmi just failed, epically :(
I guess the only good thing that came out of yesterday was that, I have errors to talk about in my discussion. u c... I didn't really think about the fact that if you put an apple in a solution it would float! Because the apples decided to float they weren't fully submerged in the solution resulting in my apples browning really weirdly. For instance the apple in the vinegar solution is really brown at the top but really white on the submerged side.... As a result of these really obscure observations & obvious errors in my experiment I have been forced to start again and am really lacking in motivation...*sigh* However, one thing I have done is....
WRITTEN UP A NEW METHOD!!!
here it is....
NEW METHOD
(Set equipment up as shown in the diagram below)
1. Get three clear, 350mL glass cups and place them on a table
2. Label one ‘A’, another ‘B’, & the other ‘C’
3. Pour 350mL of tap water into cup ‘A’
4. Pour 175mL of tap water & 175mL of vinegar into cup ‘B’ and stir the solution
5. Pour 350mL of vinegar into cup ‘C’
6. Get an apple
7. Cut it into 3 equal pieces that are 1cm in thickness
8. Place one slice of the apple carefully into each of the 3 solutions. Keep spillage to a minimum
9. Cover all three cups with a layer of cling wrap
10. Cover this layer of cling wrap with a layer of aluminium foil
11. Cover this layer of aluminium foil with cling wrap, providing a secure seal for the cup
12. Put a elastic band around the mouth of the cup so that it further secures the cling wrap/aluminium seal
13. Turn each cup from their current vertical positions to a horizontal position
14. Leave all the cups in a cool, dry place for one hour
15. Turn all cups from horizontal position to a vertical position after one hour
(Set up equipment as shown below in the diagram)
16. Get three plastic plates and place them on the table
17. Label one ‘A’, another ‘B’, & the other ‘C’
18. Remove cling wrap/aluminium seal off each cup
19. Remove the apples from the solutions using a pair of tongs
20. Place the apple from glass ‘A’ onto plate ‘A’
21. Place the apple from glass ‘B’ onto plate ‘B’
22. Place the apple from glass ‘C’ onto plate ‘C’
23. Observe apples
24. Record observations on a table like the one constructed below. Take into consideration any other significant observations. Continue the recording of observation every ten minutes for one hour.
25. Take photos of the apples every ten minutes when recoding observations & include it in recording table
26. Repeat entire experiment two more times for reliability

…ahhhh! Now that that’s done I just need to do the experiment! I have planned to start the experiment Wednesday…after school :)
Hoping that everything goes to plan,
Lakshmi :)
