MixturesMaple syrup is a mixture of water and
naturally-occurring sugars (sucrose,
fructose, and glucose).
The sugars are dissolved in the water,
so you can’t see them. When you
look at maple syrup, you cannot see
the different components of the maple
syrup. Mixtures where only one phase
is visible are called homogeneous
mixtures. In a homogeneous
mixture, the particles are evenly
distributed.
Mixtures
When you pour maple syrup on
your pancakes, you create a
heterogeneous mixture. A
heterogeneous mixture is a
mixture where the different
phases are visible. In a
heterogeneous mixture, the
particles are unevenly
distributed. Even after you have
poured the maple syrup, you can
still see pick out the maple syrup
from the pancakes.
Mixtures
Decide if each food item is a homogeneous or heterogeneous mixture.

Solutions
Maple syrup is a mixture of water and
naturally-occurring sugars (sucrose,
fructose, and glucose).
The sugars are dissolved in the water.
When one substance is dissolved in
another substance, we call the mixture
a solution. The substances that get
dissolved are called solutes and the
substance that does the dissolving is
called the solvent. Solute (eg: particles of sugar)
Solvent (eg: water)
Solutions
Solutions are homogeneous
mixtures, because you
cannot see the different
phases when you look at it.
When a solution has dissolved
the amount solute it possibly
can, the solution is called a
saturated solution. Before
that point is reached, we call it
an unsaturated solution.
