Simple Science Experiment
(While the grown-ups are doing all the Thanksgiving cooking, here is an experiment for the kids to try.)
Can you keep an apple from turning brown once that you have cut it?
Do you know the answer to this question? Come up with your hypothesis and write it in your notebook. Perform the experiment below to see if your hypothesis is true.
- One apple
- One lemon, juiced
1.Cut the apple into quarters. (Don't use a sharp knife without an adult's help!)
2. Leave one of the apple quarters on the kitchen table.
3. Place another apple quarter in the refrigerator.
4. Sprinkle lemon juice on the other two apple quarters.
5. Place one of these quarters on the table and the other in the refrigerator.
6. Check each of the apples every minute or so.
Which quarters turned brown first? Which quarters turned brown last? Record your observations in your notebook. Is the hypothesis you wrote in your notebook before you started the experiment true?
