POTATO ON DIET (Amazing Science Games and Experiments)

Materials Required:

  1. Large potato
  2. Small, sensitive scale,
    such as a postal scale or
    dieter’s food scale
  3. Pen and paper

Procedure:

  1. Wash and dry the potato; then place it on the scale. Note the weight and write it down.
  2. Now, set the potato in a dry place and leave it there for about three weeks.
  3. After three weeks, weigh the potato again. Even though the potato may look the same size to you yet it will weigh less than when you first weighed it. Has
    the potato gone on
    a diet?

This is what happens:

Water makes up a large part of most animal and plant matter. When the potato was exposed to the dry air, some water evaporated and this resulted in a weight loss. Do you know that most of your own body is made up of water?
