High School/Chemistry I
Unit Periodic Table
Concept:
Generalizations
The periodic table was developed and organized as an information tool for scientists to predict properties of
atoms.
(5) The student understands the historical development of the Periodic Table and can apply its predictive power.
TEKS:

Periodic Table History & Organization
(A)
Student Expectation: 5AB
Formal Assessment:
Clarification:
Explain the use of chemical and physical properties in the historical development of the Periodic Table;
(Supporting Std)
(B) Use the Periodic Table to identify and explain the properties of chemical families, including alkali metals, alkaline
earth metals, halogens, noble gases, and transition metals
(Readiness Std)
EOC (state), EOC (district), and Campus Common Assessments
Student should be able to answer the following essential questions:
- How did the development of the Periodic Table come about?
- What did the Periodic Table establish with regard to chemical and physical properties of elements?
- How is the Periodic Table we use today organized?
Student should be able to perform the following skills:
- Identify and explain the properties of the different chemical families
 In the EXPLAIN activity, f orbitals can be skipped since they are not covered in reg Chem. Have the students skip
this part of the instructions but let them know there are additional orbitals. You can also code all of the transition
metals with one pattern vs. separating out the “inner transition” metals.

In IPC, the student knows that relationships exist between
the structure and properties of matter. They relate physical
and chemical behavior of an element, including bonding and
classification, to its placement on the Periodic Table. (IPC

UNIVERSAL
GENERALIZATION: The
Periodic Table reveals
relationships between atoms
and elements that can be
explained by examining the
subatomic arrangement of
particles within.
Engage Activity 1:
Have the class stand up and
divide them up based on
commonalities they share. For
instance, types of shoes,
sports played, color of shirt,
start with generic
characteristics and then get
specific to form smaller
groups. Can some students
go with more than one group?

Students can work in groups or individually
on this assignment.
Or
Request Hastings Activity- Atoms Family
Explain
Part I:
Students read the
Teachers’ Domain
Periodic Table Essay
on the History of the
Periodic Table.
Discuss the basic
development of the
PT over time.
Part II:
Have students
identify the different
parts of the Periodic
Table by completing
one of the following
activities:
Elaborate
Use the activities
to reinforce what
the students have
learned:
Lab: Metals,
Nonmetals,
Metalloids
Evaluate
Evaluation should take
place while monitoring /
questioning/checking for
understanding of students
during each phase of
instruction.

Engage Activity II:WalkAround Calendar Activity
Place calendars around the
room at stations with a piece
of chart paper of questions at
each station. Have the
students respond to the
questions on the chart paper
in small groups. Allow the
students 3-4 minutes at each
station for response.
