Learning Competency/ies: explain how the respiratory and circulatory systems work Code:
together to transport nutrients, gases, and other
(Taken from the Curriculum Guide) S9LT-la-b-26
molecules to and from the different parts of the body
Key Concepts / Understandings to be
Developed When you breathe in, or inhale, the diaphragm muscle contracts. Inhaling moves the diaphragm down and
expands the chest cavity. Simultaneously, the ribs move up and increase the size of the chest cavity. There
is now more space and less air pressure inside the lungs. Air pushes in from the outside where there is a
higher air pressure. It pushes into the lungs where there is a lower air pressure. When you breathe out, or
exhale, the diaphragm muscle relaxes. The diaphragm and ribs return to their original place. The chest
cavity returns to its original size. There is now less space and greater air pressure inside the lungs. It
pushes the air outside where there is lower air pressure
Domain Adapted Cognitive
Process Dimensions OBJECTIVES:
(D.O. No. 8, s. 2015)
Knowledge Remembering
The fact or condition of knowing
something with familiarity gained
through experience or association Understanding Explain how the lungs work
Skills Applying
The ability and
capacity acquired through Analyzing
deliberate, systematic, and
sustained effort to smoothly and
adaptively carryout complex Evaluating
activities or the ability, coming
from one's knowledge, practice,
aptitude, etc., to do something Creating
Create a lung model
Attitude Valuing demonstrate appreciation of the of taking good care of the respiratory system
Values Valuing Show cleanliness and orderlines in making the lung model
2. Content The Human Breathing System: how the lungs work(Bottled Balloons )
3. Learning Resources Sci 9 LM pg 6-8, Sci 9 TG pg 7-8
4. Procedures
4.1 Introductory Activity The Students(3-5 students) will recall the key parts of the breathing system through oral recitation for 5
5 minutes minutes.
4.2 Activity
The teacher will give instructions regarding the activity for 2 minutes.The Students will be paired (preferably
20 minutes with their seatmate)and perform/answer activity 2:bottled bollons pg 6-7 in their LM for 18 minutes.
4.3 Analysis
Each pair of students will answer and brainstorm the following questions A Pair of students will then be
selected to prsent/report in class: Q4. What does each part of the constructed lung model represent?
Q5. What happens as you pull down the balloon at the bottom of the model?
5 minutes Q6. What happens as you push up the balloon?
Q7. How does the movement of the diaphragm cause the air to go in and out of the lungs?
Q8. What might happen if you prick the balloon?
4.4 Abstraction
The Teacher will explain that Oxygen is necessary for life to exist. Without it, the cells in the body would not
be able to release the energy in food for power, and they would die within minutes. When you inhale air,
your respiratory system gets oxygen. When you exhale, carbon dioxide is released. When you breathe in, or
inhale, the diaphragm muscle contracts. Inhaling moves the diaphragm down and expands the chest cavity.
Simultaneously, the ribs move up and increase the size of the chest cavity. There is now more space and
15 minutes less air pressure inside the lungs. Air pushes in from the outside where there is a higher air pressure. It
pushes into the lungs where there is a lower air pressure. When you breathe out, or exhale, the diaphragm
muscle relaxes. The diaphragm and ribs return to their original place. The chest cavity returns to its original
size. There is now less space and greater air pressure inside the lungs. It pushes the air outside where
there is lower air pressure.
4.5 Application
What will happen to your diaphragm when you inhale?When you exhale?
5 minutes
4.6 Assessment The students will answer the following Write an Essay describing how the air
Tests goes in the lungs and how does air goes out? Write your answer on a one half

When you inhale air, your respiratory system gets oxygen. When you exhale, carbon
dioxide is released. When you breathe in, or inhale, the diaphragm muscle contracts.
Inhaling moves the diaphragm down and expands the chest cavity. Simultaneously, the
ribs move up and increase the size of the chest cavity. There is now more space and
less air pressure inside the lungs. Air pushes in from the outside where there is a higher
air pressure. It pushes into the lungs where there is a lower air pressure. When you
breathe out, or exhale, the diaphragm muscle relaxes. The diaphragm and ribs return to
their original place. The chest cavity returns to its original size. There is now less space
and greater air pressure inside the lungs. It pushes the air outside where there is lower
air pressure.
