For most parts of this exercise we will work in groups of four. Each of you should write up your own lab report based on the results your group got. Briefly describe what you did, the results you got, and your interpretation of those results. Evaluate the experiment.
Quick version Use a parer to shave peels from a carrot.
Divide the peels into two groups. Place one group in a bowl with water and the other in a bowl of water with a tablespoon of salt. In a few minutes check the texture of the peels. If the celery or lettuce in your refrigerator is a little limp, you should be able to make it more crisp by dunking it into water. If it is very limp because the cells have been damaged, the water won't help.
