Even though all physical objects are made up of matter. Matter is not all the same. Your computer screen has some very different properties than the notebook. A property is something we can dectect about the matter. We can sense some of properties, like shape, color, luster, smell, taste, texture. Others can be measured such as weight, size, or volume. Still more properties can be dected by the way the materials interact with other substances. For example when what happens when you put it in water: does it float, sink, disolve? How does it interact with energy, such as heat? These things that we can detect and describe about matter are called physical properties.

One of the things a chemist can do is identify a substance by it's properties. You must begin by examining the idea of matter having properties, dectable identifiers.
