Concept B: Properties of mixtures depend
upon the concentrations, properties and
interactions of particles
a. Identify water as a solvent that dissolves
materials (Do NOT assess the term
solvent).

a. In a beaker of water, students will add sugar
and stir. Students will find out what
happened to the sugar; then boil the mixture
and explain the results. (1.3; 2.3)
a. Students will share with the class their
findings.
b. Observe and describe how mixtures are
made by combining solids or liquids, or a
combination of these.
R

b. Using vegetable soup and water, students
will observe when these are combined. They
can separate the vegetables from the soup.
(2.1; 3.5)
b. Students will record their findings and plan
and present them to the class.
c. Distinguish between the components in a
mixture (e.g. trail mix, conglomerate
rock, salad).
R

c. Students will combine nuts, oatmeal flakes,
raisins, and dried cranberries. The mixture
contains different substances. (2.2)
c. Students will separate, classify into groups
and summarize the results. Students will
compare results with a cooperative group,
reviewing and revising the classifications.
d. Describe ways to separate the
components of a mixture by their
properties (i.e., sorting, filtration,
magnets, or screening).

d. Students will mix water and sand together.
Students will stir their mixture. (3.7)
d. Students will decide how to remove the sand
from the water and evaluate the effectiveness
of the solution.

a. Students will mix a pile of rocks, dust, dirt,
salt, and bits of iron. The rocks are screened
out first. A magnet takes away bits of iron.
Water is added then the filter removes dust
and dirt. Salt water is heated. The water is
boiled and only salt is left behind. (2.5)
a. Students will draw the pile of rocks and
process for separating the components;
Students will interpret the results of their
activity.
