i've decided to do how different environments and bases added to apples affect how fast it browns.

Method

1. collect 5 plastic cups. leave one empty

2. in the other cups, pour difference bases (vinegar, water, lemon juice, solution of bicarb soda + water) into each of the remaining cups, filling abut 1/5 of the cup.

3. cut an apple into about 5 pieces.

4. put one piece into each of the cups and take note of the time.

5. leave in a cold environment (fridge?)

6. record and compare the times for when each apple starts to brown.

7. repeat steps 1-6, except leave in a hot environment instead of cold.
