12.11.53 Understand that in chemical reactions, atoms
combine into molecules by means of bonds (e.g., by
sharing electrons to form covalent or metallic bonds or by
exchanging electrons to form ionic bonds).
12.11.56 Understand that the conservation of atoms in a
chemical reaction, as summarized in a balanced chemical
equation, leads to the ability to calculate theoretical
masses of reactants and products.
12.11.57 Understand how to read, interpret, and balance
chemical equations.

11.A.3a Formulate hypotheses that can be tested by
collecting data
11.A.3b Conduct scientific experiments that control all but
one variable
11.A.3g Report and display the process and results of a
scientific investigation
11.B.4f Evaluate the test results based on established
criteria, note sources of error and recommend
improvements.

Meets
Purpose
Meets standards AND
hypothesizes combustion
products
Correctly defines the
purpose of the
experiment
Incorrectly defines
the purpose of the
experiment
Introduction
Meets standards AND
provides example of both
complete and incomplete
combustion
Correctly defines
complete and
incomplete
combustion; correctly
balances experiment
reactions
Incorrectly defines
complete and
incomplete
combustion;
incorrectly balances
experiment reactions
Results
Meets standards AND
describes the
relationship between the
independent and
dependent variable
Provides a table
summarizing the
results of the
experiment
Displays an incorrect
or unorganized
summary of the
results
Conclusions
Meets standards AND
suggests specific
improvements for future
experimentation
States conclusions
about the dependent
variable as an effect
of the independent
variable; correctly
identifies error
sources
Conclusions do not
relate the dependent
variable to
independent
variable; incorrectly
identifies error
sources
