Suppose you have a beaker of sugar and a beaker of salt. They are unlabeled and the white crystals look identical. Your assignment is to identify each one. Tasting would make identification easy, but you should never taste anything in a science lab. Instead, you can use scientific knowledge and investigation to help you identify each substance.
