Properties of materials are characteristics of matter. There are certain words used for describing them and you need them in your vocabulary. The properties of different materials make them useful for different purposes. Although it floats, cork would not be a very good choice of material if you wished to build an ocean-going ship. And, although it's very shiny, painting your wall with some gloss paint would not make a good mirror.
Does your vocabulary include the words that describe the properties of materials? See how well you understand their meanings by taking this science quiz.
