5.2 Physical Science: All students will understand that 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.
B. Changes in Matter
Content Statement
CPI#
Observations and investigations form a
basis for young learners’ understanding of
changes in matter.
5.2.P.B.1
2
Some properties of matter can change as a
result of processes such as heating and
cooling. Not all materials respond the
same way to these processes.
5.2.2.B.1
4
Many substances can be changed from
one state to another by heating or cooling.

Objectives
Explore changes in liquids and solids
when substances are combined, heated, or
cooled (e.g., mix sand or clay with various
amounts of water; mix different colors of
tempera paints; freeze and melt water and
other liquids).
Generate accurate data and organize
arguments to show that not all substances
respond the same way when heated or
cooled, using common materials, such as
shortening or candle wax.
a. Attend to science objects,
materials and activities.
b. Demonstrate an awareness of an
ongoing investigation,
experiment or project.
Predict and explain what happens when a
common substance, such as shortening or
candle wax, is heated to melting and then
cooled to a solid.
a. Make predictions about familiar
events.
b. Conduct an experiment to
change an item’s matter state.
c. Connecting matter states to
various catalysts.
a. Define states of matter by their
properties.
b. Identify ways to collect data.
c. Identify ways to organize data.
d. Conduct simple experiments and
record data.
6
When a new substance is made by
combining two or more substances, it has
properties that are different from the
original substances.
5.2.6.B.1
Compare the properties of reactants with
the properties of the products when two or
more substances are combined and react
chemically.
a. Identify the characteristics of a
substance.
b. List the characteristics of
original and final substances.
c. Define: reactant, property and
substance.
d. Identify possible chemical
reactions.
8
When substances undergo chemical
change, the number and kinds of atoms in
the reactants are the same as the number
and kinds of atoms in the products. The
mass of the reactants is the same as the
mass of the products.
5.2.8.B.1
Explain, using an understanding of the
concept of chemical change, why the
mass of reactants and the mass of
products remain constant.
a. Define mass, atom and product
b. Recognize a chemical change.
c. Demonstrate the ability to
calculate the mass of a
substance.
12
A large number of important reactions
involve the transfer of either electrons or
hydrogen ions between reacting ions,
molecules, or atoms. In other chemical
reactions, atoms interact with one another
by sharing electrons to create a bond.
5.2.12.B.2
Describe oxidation and reduction
reactions, and give examples of oxidation
and reduction reactions that have an
impact on the environment, such as
corrosion and the burning of fuel.
a. Define electron, ion and
molecule.
b. Define oxidation, reduction
reaction and corrosion.
c. Identify chemical reactions in
the environment.
d. Connect an environmental
condition to the chemical
reaction that caused it.
