Strand A: The Nature of Matter
Standard 1 SC.A.1.4: The student understands that all matter
has observable, measurable properties.
Benchmark SC.A.1.4.1: The student knows that electron
configuration in atoms determines how a substance reacts
and how much energy is involved in its reactions.
Benchmark SC.A.1.4.5: The student knows that
connections (bonds) form between substances when outershell electrons are either transferred or shared between their
atoms, changing the properties of substances.
Strand H: The Nature of Science
Standard 2 SC.H.2.4: The student understands that most
natural events occur in comprehensible, consistent patterns.
Benchmark SC.H.2.4.1: The student knows that scientists
assume that the universe is a vast system in which basic
rules exist that may range from very simple to extremely
complex, but that scientists operate on the belief that the
rules can be discovered by careful, systematic study.
Standard 3 SC.H.3.4.4: The student knows that funds for
science research come from federal government agencies,
industry, and private foundations and that this funding often
influences the areas of discovery.

Description/Abstract of
Lesson
Objectives
1 class period (50-60 minutes)
Molecules are introduced in the section entitled “Molecules”
that begins on page 35. [put link to p. 35 here] Chapter 7
describes how to write Lewis structures of molecules on pages
163-173.
 Review structural formulas,
 Give description of energy of interaction between two
hydrogen atoms as a function of distance,
 Explain that distribution of outer level (valence) electrons
are joined by covalent bonds and are most simply defined
by Lewis structures,
Teacher
Materials/Technology
Connection
 Show, using Lewis structures, single, double and triple
bonds, and
 Explain the octet rule.

Essential
Question/Vocabulary
Essential Question: How are Lewis structures representative
of covalent bonding?
Vocabulary:
 Atomic orbital
 Covalent bond
 Double bond
 Electron-deficient molecule
 Expanded octet
 Formal charge
 Octet rule
 Single bond
 Skeletal structure
 Triple bond
 Unshared pair
 Valence electron
 VSEPR model
[Can link each of the terms highlighted in red to the Glossary
file on the web site & the definition will pop up.]
In an earlier class, we identified a molecule as two or more
atoms joined together or bonded. Lewis structures give us a
visual picture of covalent bonds.
 Have students read pages 163-173 in the Student Edition to
familiarize themselves with the topic. Explain the
distribution of outer (valence) electrons.
 Outline and discuss the rules for writing Lewis structures
for single, multiple, expanded octet and resonance forms
Read pages 163 - 173
Give several formulas for molecules and have the students
discuss how to write the Lewis structures. [Link to SE pages
164 & 165] Then give a list of additional molecules for
students to draw independently to be discussed at the end of

the class. Make the Periodic Chart available to the students for
reference.[Link to page 33 SE]
Have students complete pages 133-139 in the Study Guide
and Workbook for homework. [put link to this here]
Action Research: Federal government agencies, industry, and
private foundations can influence areas of discovery through
the types and amounts of funding they make available for
scientific research. Using the Internet, find the most current
sources of funding for scientific research on covalent bonding
and write a short report on your findings. Typing the phrase
“covalent bonding research grant” into a search engine such
as Google will direct students to many sites related to grants
for research on covalent bonding.
The students present their drawings of the molecules and
discuss any questions they encountered completing the Lewis
structures. Use the example that appears within the text on
pages 164 and 165.
Assign students questions 1–20 at the end of the chapter on
page 190.
