Quarter
First
I. OBJECT
IVES
Explain the
importance of
biological
diversity.
Measure
species
distribution
using the
mathematical
way of
expressing the
amount of
biodiversity and
species
distribution in
the community.
Determine the
area distribution
of a given
population using
mathematical
formula
Infer the possible
effects of low and
high density
population.
Demonstrate
using simulation
activity that
habitat
destruction can
contribute to
species
extinction.
Relate species
extinction to the
failure of
populations of
organisms to
adapt to abrupt
changes in the
environment.
Distinguish
environmen
tal changes
that may
result in the
loss of the
species.
Realize that
the way
they
interact with
the
environmen
t may
ensure or
deters
survival of
all living
things.
Cite other
human
activities that
leads to
extinction.
Assess students acquired
skills through Summative
Assessment.

previous lesson
or presenting the
new lesson
ELICIT
Picture Analysis
Tell something about
the picture.
How do organisms
interact with each
other?
Which community
is most stable?
Why are
populations that
are more diverse
usually more
stable?
Play a short video clip.
“Endangered
Animals” What
does the
video tells us?
Is the world a safe
place for all
animals and plants
to live? Why or
why not?
What does it mean for a
species to be
endangered?
What other human
activities contribute to the
extinction of species?
B.Establishing a
purpose for the
lesson
ENGAGE
Analogy:
Present two boxes of
candies, one with 5
candies of the same
kind and the other
one with 5 different
Unlocking of word
difficulty:
Limiting Factors
Carrying Capacity
Post a Quotation.
Students reflect
and give
their insights.
Picture Analysis:
How would you
describe the
picture?

3. candies. Ask the
students which
box will they choose and
why?
What does the picture
implies?
C.Presenting
examples/
instances of the
new lesson
ENGAGE
Unlock term Species,
Population and
Biodiversity. This will lead
students to the idea of
species distribution and
diversity in a community.
Video Analysis
“ Population Growth “
What is the message implied
in the video?
Students perform
“Species Charade
Game”
A list of endangered
species, threatened
species, and extinct
species are the
choices to be
picked for the game.
Vi
What is the impact of
modernization to the
lives of people and the
environment?
D.Discussing new
concepts and
practicing new
skills #1
EXPLORE

Diversity in L.M. p.54.

4. 1.How do you
compare your tree

from a grass lawn?
Explain your answer.
If humans were concerned
about biological diversity,
would it be best to have a
low or high I.D. for a
particular environment?
Why?

How can a population’s
density be used to
learn about the needs
and characteristics of
that population?
How are limiting
factors
the organisms are not
ideal for their survival?
When can we say that
species becomes
endangered?
Becomes threatened?
How do changes in the
environment affect
species

What is its
implication in our

How do you think
or feel about these
potentially

activities?
As an individual,
how can you
help the cause
of preserving
wildlife?

concept for further
understanding.
G.Finding practical
application of
concepts and
skills in daily
living
ELABORATE
What do you think
will happen if a
population of only
one species
continue to
increase in
number?
Compare and
contrast life in a
rural and urban area.
Flash pictures of
silver therapon or
ayungin and biya.
Ask if they know

commonly found
in Laguna de Bay.)
Other endangered
species like the
tamaraw in Mindoro,
Will you
patronize
snakeskin belts,
alligator boots,
accessories
made of ivory
and other things
that made from
endangered
species? Why or
why not?
Make a multimedia
presentation of a
timeline of
extinction of
representative

Palawan, Philippine
deer, monkey-eating
eagle, and dugong
are in danger of
becoming extinct.
H.Making
generalization
and abstractions
about the lesson
How is
biological
diversity
important?
How will
the
communit
y of
different
species be
able to
withstand
environme
ntal
changes?
How do you
determine the
area distribution
of a given
population?
How does
population
density
changes?
What are the
factors that can be
attributed to the
change?
Why do species
becomes
endangered?
When can we
say that a
species’
population
becomes
endangered?
Threatened?
And Extinct?
How are the

of the changes
in their
environment?
Cite different
environmenta
l changes that
leads to
extinction.
Why should
we protect
endangered
species?
I.Evaluating
learning
EVALUATE
Give a 5 item formative
test.
Infer what will happen
If population density
increases?
Decreases?
As population of people
increases it has great impact
on the growth and
development of the
community. How will it lead
to species extinction?
Give a 5-item formative
test.
