Here is my SRP proposal which I completed last term. I received 11/12 for it and the area where I lost marks was the method because it was not clear as to how I would measure the amount of oxidized areas on the apple. So, to resolve this issue, I diced the apples into small cubes and put 100 of them in each of the bowls so that it is easy to determine which brown squares had oxidized.
To discover if apples will oxidize when lemon juice, extra virgin olive oil, vinegar and tap water has been spread onto the surface of the apple slices.
The lemon juice will have the biggest impact on preventing the apple to turn brown.
