A Lesson Plan in Grade 8 – Science

I. Session Objectives
At the end of the lesson, the students should be able to:
1. describe a fault in terms of its appearance;
2. explain how faults form;
3. identify three types of faults; and,
4. cite importance of identifying/locating faults in the nearby surrounding.
II. Subject Matter
A. Competency: Using models or illustrations, explain how movements along faults
generate earthquakes. (S8ES-IIa-14)
B. Topic
 Module I: Earthquakes and Faults – Faults
C. References
 Teacher’s Guide page 47
 Learner’s Material pages 115-132
D. Materials
 Activity Proper – folder, fine sand, ruler, newspaper/plastic sheet, fault model
 Lesson Proper – laptop, projector, video clips, fault model
E. Values Integration
 Participate in class discussion
 Respect the ideas of other classmates
 Develop confidence in answering questions
 Patience in doing the activity
F. Definition of Terms
 Fault - is a break in the Earth’s crust, and along the break, significant movement
has taken place
 Normal fault - formed along divergent boundaries; due to tension.
 Reverse fault - formed along convergent boundaries; due to compression.
 Strike-slip fault - formed along transform boundaries; due to shearing.
G. Science Processes
 Listening, Reading, Manipulating, Analyzing, Inferring

III. Learning Activities

A. Preparatory Activities:
 Prayer
 Greetings
 Checking of Attendance
 Review/Recall
The teacher will ask the following questions:
 What were the topics covered in the first quarter?
 Motivation
1. The teacher will divide the class into 6 groups.
2. They will be given a sheet of manila paper for them to record their answers.
3. The teacher will give instructions to manage the flow of pre-assessment
activity.
4. The students will be given 2 minutes to do the simple activity and report it
afterwards.
B. Lesson Proper

 ACTIVITY
1. The students will stay in the same grouping.
2. The teacher will introduce the activity to be performed.
3. The teacher will hand in the materials to the different groups.
4. Every group will be given 5 minutes to finish and record their observations.
5. After performing, one member of the group will read their output to the class.

 ANALYSIS
The teacher will ask the following about the activity:
1. As you move the sheets, what is formed in the sand?
2. What happened to the lines? Why?
  ABSTRACTION
The teacher will discuss the concept of a fault.
Fault is a break in the Earth’s crust, and along the break, significant
movement has taken place. The word “break” refers to a crack in the ground.
The word “crust” refers to the outermost layer of the Earth. We live on the
surface of the crust. “Significant movement” means that the rocks have been
displaced or shifted considerably. Earthquakes are associated with faults. When
a fault suddenly moves, an earthquake occurs. Faults form as the Earth’s crust
deforms due to stress. Generally, the movement of the tectonic plates provides
the stress, and rocks at the surface break in response to this. Three types of fault
are the following: normal fault, reverse fault and strike-slip fault.

 APPLICATION
With the same grouping, the students will make a simple illustration out of the
different types of fault using the fault models provided.

The teacher will ask the following questions:

IV. Evaluation
