Matter and Materials
All objects around us are made of matter. Matter is anything that occupies space. We find matter in three different states: solid, like ice, liquid, like water, and gas, like water vapour. We can make matter change its state by heating or cooling it. Matter is made up of an enormous number of different substances. The substances used to make objects are called materials. Materials can be natural, like wood, or artificial, like plastic.
