Mixtures and Solutions
Main Idea: Mixtures and solutions are made up
of two or more substances that are combined in
a physical change.
By: Mr. Leslie’s Class
Mixtures
 A mixture is matter
made up of two or
more substances that
are combined
physically.
 Making a mixture is a
physical change.
 Most mixtures can be
separated by hand.
(Not All)
Common Mixtures
 Bubbles
 Water
 Bowl of soup
 Glass of Milk
 Trombone
 A drawer filled with
socks
 Salt Water
 Concrete
 The water you drink
has minerals mixed
up in it.
 A trombone is made
of brass, a mixture of
metals
 Concrete is a mixture
of gravel, sand,
limestone, clay, and
water.
Solutions
 A mixture of sand and
water looks different than
a mixture of salt and
water.
 The salt seems to
disappear.
 Salt water is a special
mixture called a solution.
 A solution is a mixture in
which the particles of one
kind of matter are mixed
evenly with the particles
of other kinds of matter.
Solutions
 Do you taste the salt in
the ocean?
 You cannot see the salt
because it has dissolved.
 Dissolve means to mix
completely by separating
into particles that cannot
be seen.
 A solution is very difficult
to separate.
 How could you separate
the salt from the water?
