1. PROPERTIES OF MATTER: PHYSICAL AND CHEMICAL Matter : Anything with Mass and volume

2. PHYSICAL PROPERTIES OF MATTER  Matter has many properties. Physical properties are those that can be observed. (by sight, touch, smell, hearing, or smell)  Other examples of physical properties would be hardness, freezing/boiling points, the ability to dissolve in other substances, and the ability to conduct electricity.  Density is an important physical property of matter. It is calculated from the amount of mass in a given volume. (Think of a bowling ball vs. a volleyball; similar volume, but vastly different mass leads them to very different densities.)

3. CHEMICAL PROPERTIES OF MATTER  Some properties of matter can be measured or observed only when matter undergoes a change to become an entirely different substance. These properties are called chemical properties.  Flammability is the ability of matter to burn. (Wood is flammable; iron is not. When wood burns, it changes into ashes, carbon dioxide, water vapor, and other gases. After burning, wood is no longer wood.)  Reactivity is the ability of matter to combine chemically with other substances. (Iron is highly reactive with oxygen. When iron and oxygen combine, rust is formed.)
