I.OJECTIVES
A. Content Standard
B. Performance Standard
C. Learning Competencies/ Write
the LC code
The learners demonstrate understanding of how changes in the
environment may affect species extinction.
Make a multimedia presentation of a timeline of extinction of
representative microorganisms, plants, and animals.
Relate a species extinction to the failure of population of
organisms to adapt to abrupt changes in the environment.
(S9LT-lef-30)
OBJECTIVES
II. CONTENT
III. LEARNING RESOURCES
At the end of the lesson, the learners should be able to attain
80% proficiency level to :
a.) Find out how changes in the environment can affect
species extinction.
b.) Distinguish environmental changes that may result in the
loss of the species.
c.) Relate species extinction to the failure of populations of
organisms to adapt to abrupt changes in the
environment.

D. Integration of content within and
across the curriculum
1) English - Analyze the impact of species extinction on the
environment through persuasive writing.
2) Social Studies - Investigate how human activities contribute
to species extinction and its effects on ecosystems.
3) Math - Use statistical data to analyze the decline in
population of endangered species.
V. PROCEDURES
PRELIMINARY ACTIVITIES
A. ELICIT ( 5 minutes )
Reviewing the previous lesson or
presenting the new lesson
TEACHERS ACTIVITY
•Prayer – Ask one student to lead the prayer.
Checking tidiness of the learning area, ask students to pick up
pieces of paper found on the premises.
• Words of Welcome
•Checking of Attendance, ask the beadle to list the absentees
and hand it after the class.
•Class Rules
1. No using of cell phones during class.
2. Listen when someone is talking.
3. Raise your right hand if you want to answer or you have
questions.
4. Be cooperative with our activities.
5. Respect other’s opinion.
6. No Shouting!
Review
To activate learners prior knowledge, they will match images of
an endemic species in the Philippines with it's correct
description.
May I know you?
1. Eagle- it is an endangered species of birds in the
country due to a massive loss of habitat resulting
from deforestation in most of it's range.
2. Pawikan- locally known as pawikan, it's decreasing
number is due to the big demand for their meat, eggs,
oil, and ornamental body parts sold to other countries.
3. Carabao- it is a threatened species in mindoro. Being
used as traditional medicine, it's population is now
threatened.
4. Flower- it is one of the most beautiful flowers in the
country, considered as critically endangered plant
due to the destruction of it's wild habitat.
5. Koala- it is found in the island of palawan and now in
danger in extinction and vulnerable because of the
increase in the island-dwelling population.
The activity you have answered earlier are related to how
species adapt to the abrupt changes to environment that result
to species extinction.
B. ENGAGE ( 3 minutes)
Establishing a purpose for the lesson
Tolerance of species
Define tolerance and limiting factors. Give emphasis to the
changes in environment that lead to species extinction
(water, air, sunlight)
Ask the learners: what happens to the species if all
environmental conditions are hampered?
C. EXLORE (10 minutes)
Presenting examples/instances for a
new lesson
Collaborative Learning
1. The students will be divided into 5 groups
2. As they have already their group, they will read the comic
strip. One of them they will play as kent and the other
one as kaylee
3. They will identify and list down those abrupt changes in
the environment would lead to species extinctions.
4. They will be given 10-15 minutes to finish the task. Each
group will choose a representative to present and explain
their outputs.
Please be guided by the following criteria:
Criteria for Evaluating Group Activity
Accuracy. - 5 points
Presentation - 5 points
Cooperation - 5 points
15 points
D. Explain (15 minutes)
Discussing new concepts and
practicing new skills
Group Presentation and Video Presentation
Differentiated instructions.
The students will present their output to the class.
The teacher will appreciate every learner’s performance.
Guide Questions:
 What causes of extinction?
 How can changes in the environment affect the
continued survival?
E.ELABORATE (15 minutes)
(Generalization)
-Developing mastery (leads to
Formative Assessment)
-Generalizing and abstractions about
the lesson
-Finding practical application of
concepts and skills in daily living

Discussion
 The teacher will discuss the expected to answer
question. Topic showing PowerPoint Presentation.
Choose me in!
Students will analyze the following situations.
Following are the sets of situations that allow abrupt
changes in the environment leading populations of
organisms to be threatened or becoming extinct. Learners
can choose more than one from the list which could be the
cause of the changes on the environment in each situation.

1. The island of Palawan contains one of the oldest,
largest, and most diverse rainforest in southeast
asia. 80% of Palawan’s endemic are found on an
around Cleopatra’s needle. However, 31 endangered
and threatened species inhabit the forests.
2. On January 12, 2020, the taal volcano in the
Philippines began to spew cases, ashes, and lava,
into the air causing most of the vegetation like
coffee, rice, corn, cacao, and banana crop to be
damaged. Dozens of people perished, large numbers
of livestock and pets were also left behind and about
30% of the fish cages on the lake were destroyed.
E. Evaluate (5minutes)
