Lesson Plan in Science Grade 8 I.Objectives

The lesson plan teaches 8th grade students about electronic configuration. It aims for 85% of students to understand electronic configuration and how to determine the configuration of elements from the periodic table. The lesson introduces electronic configuration and reviews periodicity. Students locate elements and learn that the period, block, and family identify an element's configuration. Examples are provided. An evaluation assigns students to determine configurations of specific elements. As homework, students must memorize configurations for elements 51-60.

LESSON PLAN IN SCIENCE

GRADE 8

I.OBJECTIVES

At the end of the lesson, it is expected that 85% of the students will be able to:

a. know the use of electronic configuration; and

b. explain how to get the electronic configuration of the elements in the periodic table.

II. SUBJECT MATTER


Topic: Electronic Configuration

REFERENCES: Chemistry III (Frontiers in Science & Technology)

MATERIALS: Chalk, Manila paper, Adhesives, Marker and Periodic Table of Elements

PROCEDURE

A1- Prelab

Drill:

Review: Periodicity and the Chemical Behavior of elements

Motivation:

The teacher will be presenting the periodic table of elements. Then, the students will locate the
elements in the periodic table. Afterwards, the teacher will ask students on how to easily locate
the elements.
A2- Analysis

1. What are the different groups in the periodic table?

2. What are the different periods in the periodic table?

3. How to get the electronic configuration of an element?

A3- Abstraction

1. The different groups in the periodic table are: Alkali Metals, Alkaline Earth Metals, Transition
Elements, Halogens, Noble Gases, Lacthanides, and Actinides.

2. The different periods in the periodic table are: Period 1, Period 2, Period 3, Period 4, Period 5, Period 6,
and Period 7.

3. In getting the electronic configuration of an element, always remember that the number in the leftmost
side is the period, the letter is the block, and the number in the right is the family.
Example: Boron

Boron is located in the 2nd period, block p, and in the first family of halogens. Therefore its electronic
configuration is 2p1.

A4. Application

The teacher will give an element, then the students will give its corresponding electronic configuration.

1. Sodium

2. Gold

IV. EVALUATION

Find the electronic configuration of the following elements.

1. Germanium

2. Iron

3. Zinc

4. Magnesium

5. Xenon

V. ASSIGNMENT

Memorize the 51st up to the 60th element in the periodic table.
