Scientific Method The systematic process of observation, hypothesis, and experimentation used to expand and refine a body of knowledge.
Property A characteristic useful for identifying a substance or object.
Chemical Change A change in the chemical makeup of a sunstance.
Solid A substance that has a definite shape and volume.
Liquid A substance that has a definite volume but assumes the shape of its container.

Nonmetal An element that is a poor conductor of heat and electricity.
Metalloid An element whose properties are intermediate between those of a metal and a nonmetal.
What kind of properties does matter have? Physical Properties & Chemical Properties
Physical Properties can be seen or measured without changing the chemical identity of the substance.
Chemical Properties can ONLY be seen or measured when the substance undergoes a chemical change, such as a chemical reaction.
