LESSON PLAN in EARTH & LIFE SCIENCE
First Quarter
October 18, 2023
Content Standard/s: Geologic processes that occur on the surface of the Earth
such as weathering, erosion, mass wasting, and sedimentation (include the role of
ocean basins in the formation of sedimentary rocks)
Performance Standard/s: Conduct a survey to assess the possible geologic/
hydrometeorological hazards that your community may experience.
Learning Competency: Describe how magma is formed (magmatism) S11/12ES-Ic-15
I. Objective
Explain the process involved in the formation of magma.
II. Subject Matter:
A. Topic:
The Process involved in the formation of magma.
B. References MELC pp. 507
Earth & Life Science –Quarter 1 Module 7: Magmatism
C. Other Learning Source Internet, Google, Website
D. Materials
Visual Aids/Paper/Pen/Laptop/Projector
III. Procedure
A. Preliminary Activities
Greetings
Checking of Attendance
Recall the classroom standard
B. Review/Drill
What is the most abundant element in magma?
What are the 8 elements found in magma?
C. Motivation
Video Presentation of Partial Melting (Marshmallow and Chocolate).
How can you relate the melting of chocolate and marshmallow to the
melting of magma beneath the earth’s surface?
D. Activity
E. Analysis
After doing the activity the teacher asks the students the following
Questions.
a. Do you think partial melting will occur if the pressure is high in the
asthenosphere?
b. Do you think partial melting will occur if there is too much amount
of water
in the subduction zone?
c. Do you think partial melting will occur if there is direct contact of
hot
molten rock in the Earth’s crust?
F. Abstraction

The teacher presents the objective of the lesson

Discussion of the substances/elements present in magma.
The magma present in the lower crust and upper mantle of
the Earth is formed or generated through the process of
partial melting. In this process, different minerals in rock
melt at different temperature and pressure. Another factor
being considered in this process is the addition of volatile
materials such as water and carbon dioxide.
G. Application
IV. EVALUATION
Identify the substances/elements present in magma.
