Rubrics:
Score Possible answer
5
Only organism
coming from the
same species can
reproduce of their
own kind.
Offspring cannot
successfully
develop from
parents of different
species.

If the answer is
correct but lacks
some points or
incomplete
1
If the answer is
incorrect
(Students’ Action Evaluation)
Instruct the class to STAND
UP if the statement given tells
the difference between natural
biodiversity and man-made
biodiversity, and REMAIN
SITTED if it does not.
1. Man-made biodiversity was
made/designed by humans,
natural biodiversity is naturally
made.
2. Natural biodiversity in
Aquatic ecosystem is
composed of different
organism living in land, while
man-made biodiversity in
Aquatic ecosystem is
composed of the same
species of organisms living in
water.
(Teacher can add more
statements to test her
students’ understanding on
the topic)
Explain the advantage of high
biodiversity over low
biodiversity.
Rubrics:
5
In high biodiversity the risk
of damage from pest
infestation is minimized
leading to better income
due to the presence of
natural predators. Low input
of pesticides because
different pests feed on
different plants. Various soil
will be available to different
plants bec. Of the presence
of other organisms.
Organisms can feed on
different organisms, thus it
has a continuous supply of
food.Nutrient are recycled
and it can support more
organisms.
The higher is the
biodiversity the more stable
is the ecosystem.

board, is mitosis the same
with Meiosis?
How do they differ?
Give lecturette if needed.
Who can explain sperm
formation?
How many sperm cells are
formed after meiosis?
Any volunteer to explain the
egg formation?
How many eggs are formed
after meiosis?
How many number of
chromosomes are there in the
daughter cells after the whole
process?
Based on what we have
discussed, what is the
importance of meiosis in
maintaining the chromosome
number of the organism?
What is the Law of Dominance?
How does it differ from the other
patterns of inheritance?
Give lecture about the different
patterns of inheritance.

ELABORATE
In what stage chromosomes
replicate? Why do you think this
process is important?
processes involved i:
a. mitosis
b. meiosis.
In what respect do they
differ in terms of:
1. location
2. type of cell produced
(haploid & diploid)
3. Number of daughter
cells
What do you think would
happen if along the process of
meiosis, something wrong
happens? Would it affect the
organism? Why?
Board Work:
Using the different patterns of
inheritance, predict the possible
phenotype of:
1. If a white-colored rabbit pairs
with a black-colored rabbit, what
is the color of their offspring
considering the Co-dominance
pattern of inheritance?
2. Complete the table of the
Blood Type
Mother Father Child

AB O
O B
EVALUATE
Paper-pencil Test
Choose the word in the box to
identify & describe the
processes during mitosis or
meiosis.
Paper-pencil Test
Compare mitosis from
meiosis by putting √ if the
statement happens in
BOTH mitosis & meiosis,
and x if it only happens in
EITHER mitosis or
meiosis.
__1. A process wherein the
cell multiplies its number
by producing new cells.
Informal Evaluation
Instructional decision is based

students during the whole
process of learning.
Informal Evaluation
Instructional decision will be
based on students’ response in
the elaborate stage.

____1. The chromosomes
begin to pair off.
____2. The chromosomes align
at the center of the cell.
____3. The paired
chromosomes disperse in the
nucleus.
____4. The paired centromeres
of each chromosome begin to
separate.
____5. The mother cell is now
divided into two with half
number of chromosomes for
each new cell.
__2. It produces a haploid
new cells.
__3. It resulted to the
formation of a Diploid cell.
__4. Occurs in all
organisms.
__5. It produces 2 new
cells.
