```5.2.6.A.3 6th grade
Physical Science: Physical science principles, including fundamental ideas about matter, energy, and motion, are powerful conceptual tools for
making sense of phenomena in physical, living, and Earth systems science. (5.2)
Properties of Matter: All objects and substances in the natural world are composed of matter. Matter has two fundamental properties: matter takes
up space, and matter has inertia. (A)

Desired Results/Assessments
Sample Assessments
To show evidence of meeting this CPI,
students may answer the following
questions:
You are a forensic scientist who has just
been presented with an unknown
material. It is your job to identify the
5.2.6.A.3 6th grade
substance to the best of your scientific
ability. Begin by examining general
properties, the presence or absence of
which can eliminate whole classes of
substances.
1. A few of the basic starting questions
are:





How does the substance respond
to heat?
Does it dissolve in water?
Does it dissolve in any other
solvent?
If it dissolves in water, how does
the solution behave?
Compare your findings with
those known substances that you
worked with in your classroom
investigations to determine the
identity of the substance.

a vignette for use as a guide related to the
sample assessment.
