Teacher: Suzette Kerr-Brown
Class: 9I
Date: June 8, 2021
Time of day: 1:15-2:15pm
Duration: 1 hour
Subject: Integrated Science
Unit Topic: More about Matter
Lesson topic: Elements and the Periodic table
Sub-topic: The Periodic Table
General Objectives: By the end of the lesson students should be able to:
1. Know that chemical symbols are used to represent elements on the periodic table.
2. Understand that the Periodic table is a collection of elements.
3. Appreciate the use of different elements of the periodic table in everyday life.
Specific Objectives: At the end of this lesson students will be able to:
1. Identify the different periods in which the elements of the periodic table are located using
their textbooks.
2. Work individually to determine the different sections of the periodic table using their
textbooks or online resource.
3. Explain why elements are placed in groups and periods using number heads together.
Prior Knowledge: students should be able to recall that the periodic table is an arrangement of
elements with increasing atomic number.
Resources: Laptop
Teaching Strategies: Collaboration, discussion.
Key concepts/ vocabulary: elements, periods, groups, non-metals, metals, noble gas, halogens,
alkali earth metals, alkaline earth metals.
Key Skills: communicate, observe, critical-thinking, classify, and collaborate.
Content:
The Groups are numbered from one (I) to eight (VIII) using Roman numerals. The Number of
the groups tell you the number of electrons on the last shell of the atoms found in that particular
group.
Therefore all the elements in Group I have one electron on the last shell and those in group two
have two electrons on the last shell of the atom.
Group eight also known as group zero consist of elements that have the maximum number of
electrons on their last shell. For example: Helium has a maximum of two electrons on its first
shell which is also its last shell.
The Periodic Table is further divided into metals and non-metals. Elements in group I, II are
metals and Aluminum in group III. Elements in groups IV, V, VI and VII are non-metals and
Boron in group III.
Some groups of the periodic table have special names to classify all the elements within them.
For example:
 Group I elements are called the alkali earth metals
 Group II elements are called the alkaline earth metals
 Group VII elements are called the halogens
 Group VIII elements (Group 0) are called noble gases or inert gases. These elements are
considered inert because they are usually unreactive.
The Periods are also numbered and tells the number of shells possessed by the atoms of elements
within a given period. Therefore all the elements in period 1 has only one shell. Period 2
elements have two shells and so on.
