Classification
of
Matter
It is easy to describe matter classification using a
concept map. We will draw it together as we go
through these notes.Draw the map on the front
of the paper and write definitions on the back.
At the top of the front page draw:

HOMOGENEOUS MIXTURE­ mixture contains two or
more gaseous, liquid, or solid substances blended
evenly throughout.
example­ soft drinks, milk, paint, stainless steel
colloids- contains some
particles that are
intermediate in size
between the small
particles in a solution and
the larger particles in a
suspension
suspensionsheterogeneous
mixture that
separates into
layers over time
Types of
Mixtures
solutionswhen substances
dissolve and form a
