How Much Water Is in a Fruit?

Compare the volume of an orange to the volume of liquid that can be extracted out of it. Also compare the mass of an apple before and after it has been dried out. In both of these activities, children find that there is an appreciable amount of water contained in fruit. This is an interesting lesson, but one that could be left out of the unit if you are running short on time.
