Lesson Guide in Earth Science
I. OBJECTIVES
The learners demonstrate an understanding of;
A. Content Standards
1. the origin and environment of formation of common minerals and
rocks
B. Performance Make a plan that the community may use to conserve and protect its
Standards resources for future generations
At the end of the session, students are expected to:
1. Identify common rock forming minerals using their physical and
chemical properties (S11ES-Ib-5)
C. Learning
Competencies/
1.1 Describe the physical and chemical properties of rock- forming

IV. PROCEDURES
Review the four subsystems of Earth (geosphere, hydrosphere,
atmosphere and biosphere) whose boundaries matter and energy flow
A. Reviewing previous
lesson or presenting
Let the students relate the previous knowledge on the subsystems that
new lesson
make up the Earth to the present topic.

B. Establishing a purpose
of the lesson Teacher shows students the ingredients on a cereal box which
(MOTIVATION) shows calcium, potassium and iron.
Let the students share their insights to their partner.
Ask: How do we identify minerals?
The teacher models each of the test before the students do them and
shows them the data they will complete

practicing new skills 2 1. Explain the definition of mineral
(DEEPENING) 2. How are minerals imprtnat to society?
3. How can an old rock become a new rock?
Group Activity:
F. Developing mastery Create a mineral museum. Ask students to hunt around the classroom or
(POST-ACTIVITY) home for minerals or mineral derivatives that have been put to practical
use. Place the objects on a display table and make an exhibit card for
each object. The card should tell what the object is, what is made of, and
how it is used.
Explain:
G. Finding practical
“Minerals are one of the country’s essentials”
applications of
concepts and skills in
daily living
Let the students think of practices/ ways that may help conserving the

country’s natural mineral resources
H. Making generalizations
and abstractions about Ask a volunteer to summarize the key concepts learned from the
the lesson discussion.
