A. Engage.


Decipher the code (3 minutes)
The teacher will present some codes for the students to decipher.
The teacher will present some clue to help them decipher the code.
Processing questions:
 What are the words you have decode?
 Do you have any idea what these words mean?
Linking statement:
The words that you have decode are used to categorize species of animal and plants that are at
risked to be extinct just like the mammoths and dinosaurs. In connection to that, for today’s
session we will be talking about what are the major causes of extinction.
Lesson proper:
B. Explore. (7 MINUTES)
Activity 1: brainstorming activity
 The teacher will group the students into three groups
 Each group will be given an article for them to read and analyze.
Group 1:

S2d1hdTpc/edit?usp=share_link
Guide questions:
1. How would you categorize the species? (threatened, endangered, extinct)
2. What are the major causes of endangerment of the species?
3. How does the change in the environment affects the species?
C. Explain. Interactive discussion (15 MINUTES)
 The Teacher will process the activity by presenting the concepts about the major
causes of extinction.
D. Elaborate. Let’s localize!!! (15 minutes) (Problem-based approach)
 Using the same group.
 Students are asked to think of the most evident problem that if not reprimanded can
cause extinction and what can they do as students to minimize and help prevent the
said problem.
Instruction: Think of an existing problem in your community that can contribute to
extinction of species. Make an action plan on what you would do to help mitigate the
problem.

Problem:
Objectives
(list of team
objectives)
Tasks
(what you need to
do to achieve your
objectives)
Success Criteria
(How can you identify
your success)
Time frame
Guide questions:
1. What problem have you observed in your community that can contribute to
extinction?
2. What solutions can you do to help mitigate the effect of the said problem?

Each group will present their work through power point presentation.
E. Evaluation (5 minutes)
 A short quiz will be given at the end of the session.

4. The end of existence of a known species is called ___________.
a. Degradation
b. Extinction
c. Migration
d. Adaptation
5. It is characterized by altered weather patterns, increased temperature globally
resulting in changes in environmental thresholds beyond the species can tolerate.
What major cause of extinction is it?
a. Climate change
b. Pollution
c. Habitat loss
d. Extinction
