(Let the teacher count 1, 2, 3)
2. Prayer
Let us pray.
3. Greetings
Good afternoon, class!
Please be seated.
4. Checking of Attendance
Class secretary, do we have any absent
for today?
5. Checking of Assignment
Class, do we have an assignment?
(As the teacher counts, the students will:
1 – arrange the chairs;
2 – pick up the pieces of paper; and
3 – are now ready to pray.)
(The students will pray.)
Good afternoon, ma‟am! It‟s nice to see you.
Thank you.
(The class secretary will report the attendance
of today.)
Yes, ma‟am.

3. Kindly exchange notebook and check if
your seatmate has an assignment. Write
checked by and later, you will pass that
notebook. Is that clear?
Yes, ma‟am.
b. Recall:
Teacher‟s Activity Student‟s Activity
Last Friday, we discussed about
Circulatory System and for our review, let
us have a simple game which I call “Pass
the Chip”. I have here three chips, I will
play music and while it is playing, you will
pass the chip. When the music stops, the
person holding the chip will answer the
question. You can answer the question by
arranging the jumbled letters. Is that clear?
Are you ready?
Questions:
- It is a fluid tissue where blood cells and
platelets are suspended.
LOBOD
- What are the three types of blood cells?
DRE DBOLO LESCL,
HTEIW BODOL LESCL,
LELTEPTAS
- It is a muscular organ that rhythmically
contracts to force blood around the
body.
REHAT
Do you have any question on our previous
topic?
Very good! This time, let us now proceed
to our new topic.
Yes, ma‟am.
Yes, we are ready.
Answers:
- Blood
- Red blood cells, White blood cells, and
Platelets
- Heart
None, ma‟am.
c. Motivation:
Teacher‟s Activity Student‟s Activity
Before we start discussing it, I need
two volunteers.
(The students will raise their hands to
volunteer.)

4. Listen carefully to my instructions. If I
say „brain‟, you‟re going to put your
hands in your head; when I say „heart‟
place your hands at chest level, in a
heart shape; and when I say „touch‟,
stretch your hands sideward. Is that
clear?
This time, let‟s do it faster.
Thank you. You may now take your
seat.
Class, what can you say about the
actions of the bodies of your two
classmates whenever I give the
instruction?
Very good! Based on the responds of
their bodies, we can conclude that the
human body has the ability to control
and coordinate activities. Which organ
system do you think is responsible for
this characteristic?
Perfect!
(The two students will go in front.)
Yes, ma‟am.
(The two students will execute the actions
based on the given instruction.)
(The two students will execute the actions
based on the given instruction in a fast
manner.)
Their bodies responded quickly as you give
them instructions.
Nervous System.
d. Lesson Proper:
Teacher‟s Activity Student‟s Activity
1. Pre-Activity:
The nervous system enables the body to
respond quickly to change in the
environment by accomplishing its
functions. Now, let us find out what are
the functions of the nervous system by
having this very simple activity which I
called “Which is Which!” I will flash
two functions then I want you to
analyse and determine which among
the two functions is the function of the
nervous system. Did you get it?
Very good! Let‟s start.
Yes, ma‟am.

5. 1. It exchanges gases between the external
environment and the blood.
2. It gathers information both from the
outside world and from the inside of the
body.
Very good! How about the next one?
1. It transmits information to the
processing areas in the brain and spinal
cord.
2. It produces hormones that regulate the
activities of cells and organisms.
Exactly! Next, is it function #1 or
function #2?
1. It processes information to determine
the best response.
2. It digests and absorbs nutrients from
the food.
Brilliant! Lastly, is it function #1 or
function #2?
1. It maintains posture and position of the
body.
2. It sends information to muscles, glands,
and organs so they can respond
correctly.
Excellent, class!
To learn more about the nervous
system, let us have a group activity. I
prepared envelopes for each group
containing the materials and
procedures.
Before we proceed to our activity, let
us discuss first the rubrics for the
activity.

and parts of the nervous system by
completing the graphic organizer.
None, ma‟am.
(Each group will clap.)

7. Group 3 – arrange the puzzle, label, and
tell the functions of the three main parts
of the brain.
Group 4 – role play about problems and
disorders of the Nervous System.
3. Post-Activity:
Are you ready for the presentation?
Very good, class! Give yourself a:
1. Amazing clap
2. Mommy Dionisia clap
3. Kiss Your Brain clap
4. PakBet clap
4. Discussion:
Based on the activity, what are the two
main divisions of the Nervous System?
How will you differentiate the two?
Very good! Our bodies coordinated
because we have a Central Nervous
System. It is consists of the brain and
spinal cord. What do you think is the
function of the brain?
Good! The brain is divided into three
major parts. What are those?
Exactly! The cerebrum is the largest
part of the brain; it is where learning,
intelligence, and judgment occur. The
cerebellum coordinates voluntary
muscle movements and maintains
balance and muscle tone. The
brainstem controls the heartbeat,
breathing, and blood pressure and
coordinates involuntary muscle
movements.
The Peripheral Nervous System has
two main divisions. What are those
two?
Yes, Ma‟am. We are all ready.
(The students will present their work.)
(The students will clap.)
The Central Nervous System and Peripheral
Nervous System.
The Central Nervous System is the main
processing center for the entire nervous system
while the Peripheral Nervous System connects
the Central Nervous System to the organs.
The brain functions as organizer and
distributor of the information for the body.
The cerebrum, cerebellum, and brainstem.
The Somatic System and the Autonomic
System.

8. How will you differentiate the two?
Great! The Somatic System has two
main parts: the spinal nerves and
cranial nerves. How will you
differentiate the two parts?
Excellent! The other division which is
the Autonomic System has
subdivisions. What are those?
Very good! The Sympathetic division is
activated in times of physical or
emotional stress or whenever the body
requires action. It controls the “fight-
or-flight” response that you experience
during a stressful situation like the
nervousness you experience when
talking in front of an audience or taking
a surprise quiz.
The Parasympathetic division maintains
body functions and restores the body to
normal or relaxed mode.
Any questions?
5. Generalization:
This time, let us play a game entitled
“Fact or Bluff”. I will give you sets of
statements and you‟re going to analyse
it whether it is true or not. If it is true,
raise the paper with the word „fact‟ and
„bluff‟ if otherwise. Is that clear?
Are you ready?
Questions:
- Central Nervous System is
composed of the brain and the
spinal cord.
- You are frightened. This will cause
to activate your Parasympathetic
Nervous System.
- Cerebrum, Cerebellum, and
Brainstem are the three main parts
The Somatic System is associated with the
voluntary control of body movements while
the Autonomic System is associated with the
involuntary control of body movements.
The spinal nerves carry motor and sensory
signals between the spinal cord of the body
while the cranial nerves carry information into
and out of the body.
The Sympathetic division and the
Parasympathetic division.
None, ma‟am.
Yes, ma‟am.
Yes, Ma‟am.
Answers:
- Fact
- Bluff
- Fact

9. of the brain.
- Spinal nerve is a tube-like organ of
neurons and blood vessels.
- Autonomic Nervous System is a
division of Peripheral Nervous
System that controls contractions of
the heart muscle.
Any questions so far?
6. Application
Class, kindly give some problems and
disorders of the nervous system?
