Unit 3: Atomic Structure
Time Frame: Oct 5 through Nov 1
Science > Physical Science > Unit 3
Unit Description
Utilizing inquiry processes and modeling techniques, students
explore current atomic theory. Emphasis will be placed on
utilizing the periodic table as a tool to understand periodic
trends and chemical nomenclature. Through research and
discussion, students will differentiate between fission and
fusion and debate the issues relating to nuclear reactions and
radiation.
Enduring Understandings
 Within and among systems where parts relate to other
parts, input from one system may be output for another.
 Models are used to think about concepts or processes that
may be abstract, not easily observed, or potentially
dangerous.
 Systems tend to change in order to reach stability; changes
in surroundings can interrupt stability.
 Science is an evolving body of knowledge and a process of
understanding the world around us.
Essential Questions
 How can systems be interdependent?
 What can models tell us?
 Why do stable systems change?
 Why is science always changing?
Student Understandings
Knowledge of atomic structure includes identifying subatomic
particles and comprehending various models of the structure of
the atoms. Students will draw Bohr models, identify
implications of the arrangement of the periodic table and
explain periodic trends. Students will learn to name
compounds and identify ionic and covalent compounds.
Students should be able to differentiate between atomic fission
and fusion and their end products.

Guiding Questions
1. Can students interpret models of atoms (Thomson’s Plum
Pudding Model, Rutherford’s Model, Bohr Model, and
Electron Cloud Model)?
2. Can students list the major components of an atom and
provide the charge for each?
3. Can students recognize and explain patterns, simple
