Detailed Lesson Plan in Science –9
I.
Objectives:
At the end of 60 minutes, the students are expected to achieve 75% level of proficiency
of the following:



Characterize a volcano.
Describe the different types of volcano; and
Classify volcanoes as active or inactive.
A. Content Standards:
The learners demonstrate an understanding of volcanoes found in the Philippines.
B. Performance Standards:
The learners shall be able to demonstrate precautionary measure before, during and after a
volcanic eruption.
C. Learning Competencies/Objectives LC Code:
1. Describe the different types of volcanoes; LC Code: S9ES-IIIa-25
2. Differentiate between active and inactive volcanoes; LC Code: S9ES-IIIa-27
II.
Subject Matter:
A. Topic: Volcanoes
B. References: Science-9 Learners Module pp.163-181; www.environmentalatlas.ae ;and
Microsoft Student with Encarta Premium
C. Materials: Pictures of Volcanoes, List of Volcanoes in the Philippines,
Manila paper, marker, Map of the Philippines, and Color pen
D. Teaching Methods: Group Work Strategy,
E. Science Concept: A volcano is an opening in the surface of the earth where molten
rocks, hot gases, smoke, and ash are ejected. Volcanoes are classified according to
record of eruption as active or inactive and; shape of volcanic cone as shield, cinder, or
composite. The heat flowing from inside the earth is tapped as source of electricity in the
geothermal power plant.

5. Review
 What does Biodiversity means?
Bio means Life and Diversity means variety.
Biodiversity means a variety of life.
6. Motivation
 Picture Analysis:
Show a picture of a different types of a
Volcano

Since you were in elementary, you have
heard about volcanoes. But do you know
what a volcano is?
7. Presentation
 The Philippines is located along the Ring of
Fire. The most famous among our
volcanoes is the Taal Volcano that has
erupted recently.
 According to PHIVOLCS, our country has
more than a hundred volcanoes as of 2013.
Twenty-three are active while the rest are
inactive.
 Let the Student watch the video regarding
About volcanic structure

B. Developmental Activities
Group Work Activity:
“ Volcanoes in the Philippines”
Directions:
 Group yourselves into three namely:
Luzon, Visayas, and Mindanao.
 Luzon group is given the tasks to characterize a volcano using a concept map.
 Visayas group is given reading text about
the types of volcanoes.
 Mindanao group by using the Philippines
map, plot the location of the following
volcanoes.
Assign colors for the volcanoes. Indicate
this in the legend.
 Work harmoniously and cooperatively.
-Student are actively see the picture.
- Yes Teacher


You are given 15 minutes to
do the task. Select one from your
group to share your work with the
class and cooperate.
Display your outputs on the
board. Say something about it.
*Presentation of outputs.
*Lecturette
C. Discussion

Using a projector (Slide Show) to present
to the class, progressively run through the
slides to impart all the key points about
volcanoes.
D. Generalization

What is a volcano?

A volcano is an opening in the surface of
the earth where molten rocks, hot gases,
smoke, and ash are ejected. Volcanoes
are classified according to record of
eruption as active or inactive and; shape
of volcanic cone as shield, cinder, or
composite. The heat flowing from inside
the earth is tapped as source of electricity
in the geothermal power plant.
E. Valuing Focus
 It is important for us to know how this
natural phenomenon happens and how to
reduce the risks and effects it may cause.
