Earthquake Detailed Lesson Plan

1.OBJECTIVES
At the end of a 60 minutes session, each student must be able to: 1.1 differentiate active, inactive, and reactive fault by their chance to produce an earthquake 1.2 locate the different areas in the Philippine map which lies near active faults 1.3 demonstrate the different movement patterns of tectonic plates concerning earthquake

2.LEARNING TASK
2.1Unit: Earthquakes and Faults
2.2Topic:
2.2.1Active and Inactive Faults
2.2.2Philippine Fault System
2.3Concepts
2.3.1An earthquake (also known as a quake, tremor or temblor) is the result of a sudden release of energy in the Earth’s crust that creates seismic waves. 2.3.2The seismicity, seismism or seismic activity of an area refers to the frequency, type and size of earthquakes experienced over a period of time. 2.3.3There are two types of fault: active and inactive faults.

3.1 Daily Activities
3.1.1Prayer/Greetings
Angenine lead the prayer.Our father who are in heaven…
(students will follow)

3.1.2Checking of Attendance
Group 1 is there any absent?I’m glad to say that no one is absent in our group
What about group 2?(each representative of the group
will be doing their attendance report)

3.2 Motivation
TEACHERS ACTIVITY| STUDENTS ACTIVITY|
Class, you are about to watch a video clip. Please observe silence and watch carefully. ( presentation of video clip) (after the video clip)What do you think is the reason behind the destruction of the city?Yes, it is an earthquake. Now we are going to find out how an earthquake forms, the kind of faults and their difference in terms of the chance they are likely to produce an earthquake, and the Philippine fault system. | An earthquake, because as observed the ground and all the buildings shake dramatically.| 3.3 Lesson Proper

3.3.1Introduction
Each year the southern California area has about 10,000 earthquakes. 3.3.2 PresentationStandards for viewing: * silence * avoid unnecessary movements * focus * observe carefully3.3.3 Comparison and AbstractionAn earthquake (also known as a quake, tremor or temblor) is the result of a sudden release of energy in the Earth’s crust that creates seismic waves. Earthquakes are measured using observations from? Aside from volcanic activities, faulting is the common cause of earthquakes. There are two types of fault. What are those? An active fault is a fault that is likely to have another earthquake sometime in the future. Faults are commonly considered to be active if there has been movement observed or evidence of seismic activity during the last 10,000 years. Inactive faults are structures that we can identify, but which do not have earthquakes. As you can imagine, because of the complexity of earthquake activity, judging a fault to be inactive can be tricky, but often we can measure the last time substantial offset occurred across a fault. If a fault has been inactive for millions of years, it’s certainly safe to call it inactive.

However, some faults only have large earthquakes once in thousands of years, and we need to evaluate carefully their hazard potential. As I had explained, in terms of earthquake production. What do you think is the difference between active and active fault? The Philippine Fault System is an inter-related system of faults throughout the whole of the Philippine Archipelago, primarily caused by tectonic forces compressing the Philippines into what tectonic geophysicists call the Philippine Mobile Belt. Do you have any follow up questions, clarifications, or anything that is not clear to you regarding earthquakes?That concludes our discussion.| Seismometers or seismograph.Active and inactive faults.Active fault has a high risk of producing earthquake, while an inactive fault has a very small chance.None. Everything is clear.

3.3.3Generalization
Earthquake are caused by faulting and measured by seismograph. There are two types of fault namely: active and inactive fault. Philippines has its own fault system, they are interrelated throughout the whole archipelago.

3.3.4 Application
A. Explain briefly the significance of knowing where the faults are located.
B. Draw the three diagrams showing the different patterns of plate movement. C. Given a Philippine Map, locate the areas that lie near fault lines correctly by tracking it using a marker.
