We most likely recognize a material by its appearance, sometimes aided by other senses such as touch, smell, and taste. Our senses detect some properties of a material, but we rely more on instruments and tests of other properties for an objective identification and analysis.

In this unit of study, we raise your awareness as to what properties to look for, where to find them, and how to make some senses out of a list of properties. This unit is didvided in the following headings:
