Introduction

This science experiment focused on how different liquids affect apples.

1. To set up the experiment, set out five containers with a few apple pieces in each one.

2. Label the five containers with the name of the liquids you are going to use: Lemon, Winegar, Water, Tonic Water, Soda

3. Once everything is set up, pour the appropriate liquids into each cup.

4. If you want, you can also set up a “control” cup of apple pieces without any liquid.

5. Then wait and see the chemical reaction.

6. After a few hours, check on the apples and talk about your observations. Record observations on the Recording Sheet if you choose.

Conclusion:

Oxidizing happens when the apples come in contact with the oxygen in the air and begin to react, turning brown. There is an enzyme in the apples, that when exposed to oxygen, turns the apple brown. Lemon juice, for example, keeps the apples from browning, because it slows down this enzyme. Keeping the apples submerged regardless, will help to cut off the oxygen supply to the apples.
