Vocabulary
Investigation 1
mixture – two or more materials together
matter – something that occupies space
liquid – state of matter that has mass, takes up space, has a definite
volume, but has no definite shape
solid – state of matter that takes up space, has a definite shape and
volume
gas – state of matter that is colorless, takes up space, but does not
have a definite volume or shape
property – characteristics of an object
solution – special mixture formed when a material dissolves in water
dissolving – process by which a solid material seems to disappear into
a liquid

powder
mass – a measure of the amount of matter in an object
evaporation – process of a liquid drying up; it turns into a gas and
goes in to the air
crystal – solid form of a material that can be identified by its
properties, such as shape, color, and pattern
