Suggested Assessments
These samples assessments offer ideas and are not
meant to limit teacher or student resourcefulness
a. Using the Kinetic Theory model, illustrate and
account for the physical properties (i.e., shape,
volume, malleability, and viscosity) of a solid,
liquid, or gas in terms of the arrangement and
motion of molecules in a substance
R
a. Students will use models and physical
examples to describe how the Kinetic Theory
best explains differences in solid, liquids and
gases. (1.3; 1;5. 1.10; 2.4)
a. Students will explain from various examples
how physical properties can be understood as
interactions between the atoms and molecules
of the substance.
b. Use the Kinetic Theory model to explain changes
in the volume, shape, and viscosity of materials in
response to temperature changes during a phase
change
R
b. Students will demonstrate how heat can
change the viscosity (oils, etc.), the size (ball
and ring experiment), and shape of substances.
(1.3; 1.5; 1.8; 2.4)
b. Students will predict the changes that will
occur when various substances undergo a heat
change.
c. Predict the effect of transfer on the physical
properties of a substance as it changes to or from a
solid, liquid, or gas (i.e., phase changes that occur
during freezing, melting, evaporation, boiling,
condensation)
Concept E: The atomic model describes the
electrically neutral atom
Concept F: The periodic table organizes the
elements according to their atomic structure and
chemical reactivity
Scope and Sequence – Physical and Chemical
Properties and Changes of Matter
R
c. Students will investigate phase changes in
simple substances (water, wax, solder) in the
laboratory. (1.3; 1.10)
c. Students will perform an actual demonstration
using common items to show the phase
changes that occur in that substance.
Not assessed at this level
a. Recognize that more than 100 known elements
(unique atoms) exist that may be combined in
nature or by man to produce compounds that make
up the living and nonliving substances in the
environment (Do not assess memorization of
Periodic Table)
a. Teacher will introduce the concept of the
Periodic Table of the Elements. (2.3)
a. From samples of various pure substances,
recognize that they are each made of elements
listed on the Periodic Table.
