Earth and
LIFE SCIENCE
First
The learners demonstrate an understanding of:the three main categories of
rocks; the origin and environment of formation of common minerals and
rocks
1. identify common rock-forming minerals using their physical and chemical
properties (S11/12ES -Ia-9)
ADM Module
EARTH and Life SCIENCE – Module 3 – MINERALS
-Preparation check. (Prayer, Attendance Checking etc.).
Anecdote 1: Ask students what they think minerals are and where they can
be found.
B. Engage
Introduce the concept of minerals and their importance.
Activity 1: "Mineral Mystery Box"




Divide the class into 2 groups.
Place a mineral sample in each box.
Ask students to feel the mineral inside the box (without looking) and
describe its properties (texture, weight, etc.).
Guide students to relate their observations to the characteristics of
objects around them.
Teacher will ask the learners the ff.:
1.How does the mineral feel?
2.Is it heavy or light?
3.Is it smooth or rough?
4.What do you think this object is?
 Core Value Integration: Makadiyos - Start by acknowledging the beauty
and variety of minerals as part of the natural world created by God.
C. Explore
Activity 2: "Mineral Investigation"
Republic of the Philippines
Department of Education
Instructions:






Divide the class into the 2 groups.
Provide each group with a set of mineral samples, hand lenses,
streak plates, glass plates, nails, data sheets, and other materials.
Instruct students to observe and test the physical properties of each
mineral sample (color, streak, luster, hardness, cleavage/fracture).
Demonstrate how to perform each test safely and accurately.
Students record their observations on the data sheet.
Each group will have 1 representative to present the observations in
front of the class.
Teacher will ask the ff.:
a.What is the color of the mineral?
b.What is the color of its streak?
c.Is it shiny or dull?
d.Can it scratch the glass plate?
e.How does the mineral break?

D. Explain
Core Value Integration: Makatao - Emphasize the importance of
teamwork, respect for each other's ideas, and proper use of materials
during the investigation
What are Minerals?
Minerals are the building blocks of rocks. Mineralogists use the criteria to
determine whether a material is classified as a mineral or not.
Characteristics of Minerals
1. naturally occurring- a product of Earth’s natural processes
2. inorganic- it must be product of Earth’s physical processes.
3. homogeneous solid- minerals should have definite volume and rigid shape
4. definite chemical composition—represented by a chemical formula
5. orderly crystalline structure- atoms of minerals are arranged in an orderly
and repeating pattern
Properties of Minerals
To identify minerals, mineralogists observe the following properties:
a. Color - mineral’s color may change depending on the surface.
b. Streak - color of mineral in powdered form.
c. Hardness - minerals resistance to scratching
Mohs Scale of Hardness (Diamond is the Hardest with a scale of 10)
10 - Diamond
9 - Corundum
8 - Topaz
7 - Quartz
6 - Orthoclase
5 - Apatite
4 - Fluorite
3 - Calcite
2 - Gypsum
1 - Talc
d. Cleavage - mineral’s resistance to being broken and fracture
e. Crystalline structure or habit
f. Diaphaneity/amount of transparency - ability to allow light to pass
through it. This is affected by chemical makeup of the mineral sample.
g. Luster - how light is reflected off a surface
h. Tenacity - describes the minerals reaction to stress.
Brittleness- a mineral turns into powder
Republic of the Philippines
Department of Education
Malleability a mineral can be flattened by pounding with a hammer.
Ductility- A mineral can be stretched into wire.
Flexible but inelastic-Minerals are bent but they remain in the new
position.
Flexible and elastic- Minerals are bent, and they bring back to their
original position.
Sectility- ability of minerals to be sliced by a knife.
Core Value Integration: Makakalikasan - Discuss the importance of
minerals in the environment (e.g., as components of soil, as resources for
plants and animals).
E. Elaborate
Activity 3: "Mineral Identification Challenge"




Provide each group with a new set of unidentified mineral samples.
Instruct students to use their knowledge of mineral properties and
testing skills to identify the minerals.
Students record their identifications and justifications on a
worksheet.
Encourage students to use reference materials (textbooks, charts,
online resources) to help them.
Teacher will asks the ff.:
a.Based on your tests, what could this mineral be?
b.What are the key properties that help you identify it?
c.How can you be sure of your identification?
Core Value Integration: Makabansa - Discuss the economic importance of
minerals in the Philippines (e.g., gold, copper, nickel) and how they
contribute to the country's development.
F. Evaluate
I- Directions: Read each questions carefully. Choose and encircle the letter of
your answer.

V. REMARKS
VI. REFLECTION
VII. OTHERS
A. No. of learners who earned
80% on the formative
assessment
B. No. of learners who
require additional activities
for remediation
C. Did the remedial lessons
work? No. of learners who
have caught up with the
lesson.
D. No. of learners who
continue to require
remediation
E. Which of my teaching
strategies worked well? Why
did it work?
Direction: Write a short reflection in a short bond paper
Upon knowing the value of minerals in our everyday life, as a student how
can you help in conserving and preserving the natural sources of these
minerals? (For example, graphite is a mineral found in pencil).
