Knowledge:
In addition to score 3.0 performance, the student demonstrates in-depth inferences and applications that go beyond what was
taught.
Students demonstrate they have developed an understanding of:
 that substances often are placed in categories or groups on the Periodic Table if they react in similar ways
 use the periodic table to create a diagram of the structure of an atom and determine if it will bond with another
element
Students will recognize or recall:
Specific vocabulary such as:
atom, proton, neutron, electron, nucleus, energy level, atomic number, atomic mass, positive, negative, neutral, bond
Basic knowledge such as:

use the periodic table to locate an element with specific characteristics
the reasoning for an element’s placement on the periodic table
the relationship between protons, neutrons and electrons
the atom as a basic building block of all matter
In addition to score 3.0 performance, the student demonstrates in-depth inferences and applications that go beyond what was
taught.
Students demonstrate they have developed an understanding of:

2
that substances react chemically with other substances in predictable ways to form new substances (compounds)
which have different properties
 that in physical changes and chemical reactions, atoms do not appear, disappear or change their identities
 atoms may bond by giving, taking or sharing electrons with each other. Chemical reactions occur when the bonding
arrangement among atoms changes, resulting in the change of reactant substances into products
Students will recognize or recall:
Specific vocabulary such as:
electron, bond, reaction, chemical, conservation, mass, valance, matter, physical, reactant, product, energy, element,
compound, substance
Basic knowledge such as:
 the difference between a chemical and a physical change
 in a chemical reaction, atoms gain, lose or share electrons
 the signs a chemical reaction has taken place

Learner Objectives
I Can:

analyze and interpret
the properties of
products and reactants
to determine if a
chemical reaction has
occurred.

interpret a model to
determine if matter is
or is not conserved in a
chemical reaction, and
explain the reasoning.

conduct an experiment
to determine if energy
is absorbed or released
during a chemical
reaction.
