Detailed Lesson Plan
In Science 8
Biodiversity
I. Objectives:
At the end of the lesson, students are expected to:
A. Classify organisms according to the taxonomic classification,
B. Describe the hierarchy in taxonomic classification; and
C. Identify the naming system in in which organisms has two names.
II. Subject Matter
A. Topic: Classifying and Naming Organisms
B. References: Science Teacher’s Guide 8, pp.169 - 197
Science Learner’s Module 8, pp. 291 - 306
C. Science Process Skills: Describing, differentiating, observing and analyzing
D. Strategies: guided inquiry, deductive reasoning, Science technology and society,
cooperative learning, brain storming
E. Materials: laptop, TV, boxes, printed materials
F. Valuing: Organism are given names in order for us to identify them and easy to
classify. Just like the binomial system, we used names to identify one specie for
convenience with being duplicated.

: Genetic diversity, ecosystem diversity,
and species diversity.
: Genetic diversity is variety of genes
present in one population, ecosystem
diversity variety of ecosystem in one
biosphere, and the species diversity is
variety of life forms present in a
community.
: Biodiversity is consist of plant and
animals living in an environment.

D. Motivation
Now class, let us play a game called
“SHERAGE”.
I will group you into 5. Now class let’s
do a quick count. Group one will stay here,
group two, three, four and five. Choose
your representative and that representative
will go in front and pick up small strip of
paper. May I ask the representative of
group 5 to read the instructions in the : Choose a representative to go in front to
monitor.
act. He/she will pick strip of paper. In order
to identify the word being acted, group
mates must guess the word. I will give 10
minutes to finish the activity. The first
group to finish will be declared as the
winner.
Thank you. This will our score board.
Class, what are the three guidelines in
doing an activity?
Yes, Kirvie?
That’s right!
Is that clear?
Your timer starts now!
Are you all done class?
It seems that group 3 finished the
activity first. Everybody let’s give them a
balyena clap.
D. Presentation of the Topic
What word did you identify, group 1?
How about group 2?
Group 3?
Group 4?
And group 5?
What do you notice with the words?
Correct! Today we are going to tackle how
are organism are given names whether it is
common name, local name, or scientific
name.
Are you class?
Let us do an activity entitled “What’s in
a name?”
I will give 10 minutes to finish that
activity.
Exactly!
If that so, what do you think is our topic
for today? Yes, Kim?
Precisely!
Now do you want to explore the world
of digestive system?
Under your box are puzzled pictures to
be fixed.. You only have 5 minutes to
complete the puzzle. If you are done, just
clap three times.
The timer starts now!
Are you all done, class?
Representatives from each group will
discuss the picture that you were
completed. Let’s start with group 1, then 2,
3, and 4.

: Protease and lipase which help break
down proteins ma’am.
Excellent!
After swallowing, the food turned into
a bolus and then go to the esophagus or

food to survive? Yes, Rein?
That’s correct!
What will happen if we do not eat for at
least 1 day?
Why are there people who are

Ma’am.
malnourished?
Why do you think they are
malnourished? Yes, Mirasol?
Exactly, Mira.
People that do not have good and stable
job tend to skip meals for money.
Why they do not have good and stable
job?
Yes, Gizel?
Exactly!
They do not pursue their education and
and that leads to poor income.
Please pursue education.
Mechanical and chemical digestion ma’am.
G. Generalization
Let’s see if you remember our topic.
What are the 2 types of types of digestion
class?
Yes BJ?
Very good.
