Day 1-2
OBJECTIVES:
1. Identify the key parts of the breathing system
2. Describe the function of each part of the breathing system
3. Explain how lungs work
4. Describe how the movement of the diaphragm helps the air go in and out of the lungs
SUBJECT MATTER
A. Topic:
Respiratory System
B. Reference:
Science learner’s module 9 pp. 4-7
LEARNING ACTIVITIES
A. Recall
Assessing by the use of an A.R guide
What do I Know about the Respiratory
System before the discussion
What do I Know about the Respiratory
System after the discussion
B. Motivation
The students brought out bunching fruits and vegetables or too look for tree branches.
C. Lesson Proper
a. Materials:
Bunched of fruits vegetables or even branches of trees
b. Procedure:
The students are to identify the different parts of the respiratory system using the
bunched of fruits.
Guide questions
a. What does each part of the bunched model represent in relation to the
breathing system?
b. How will you describe the pathway of oxygen in the breathing system?
c. What will happen if one part of the system fails to carry out its function
properly?
d. What happens to the muscle of the diaphragm when you inhale or exhale?
D. Generalization
a. What is the key concepts to emphasize?
The air we breathe goes through our nose, nasal passage, and then through trachea
or windpipe, which separates into two branches, called bronchial tubes or bronchi,
one entering each lung. The bronchi is subdivided many times inside the lungs,
analogous to the branching pattern of the models in used, finally becoming hair like
tubes called bronchioles. In the last part of the terminal bronchioles are tiny bubble
like bunch of structures called alveoli or air sacs. When you breathe or inhale the
diaphragm muscle contracts then expands and the chest cavity taking less air
pressure inside the lungs while if you exhale the diaphragm muscle relaxes taking
great pressure inside the lungs.
IV.
EVALUATION:
By using the A.R guide they are going to write down what they have understand after the
discussion. (n.g)
V.
ASSINGMENT
1. Describe the blood flow inside of the heart.
Day 3-4
I.OBJECTIVES:
1. Identify the key parts of the circulatory system ;
2. Describe the function of each part of the circulatory; and
3. Explain how the circulatory works with the respiratory system.
II.SUBJECT MATTER
III.
A. Topic:
Circulatory System
B. Reference:
Science 9 pp. 10 - 14
LEARNING ACTIVITIES
A. Recall:
1. Identify parts of the respiratory system and to emphasize capillaries and alveoli
through Socratic Method of analysis and discussion.
B. Motivation:
2. Using a faucet inside the room to introduce the blood flow
C. Lesson Proper
a. Materials:
Books, chalk and board
b. Procedure:
IV.
V.
Socratic Method of analysis and discussion. The students are going to organize their
ideas on the circulation of the blood through the heart going through out of the
body.
Guide questions:
1. What are the 3 types of circulation?
2. Differentiate the three types of circulation.
3. What is the 3 types of vessels and describe the function of each vessel?
4. What are the parts of the parts and describe function of each parts?
5. How does each function work as a system?
6. How can respiratory work with the circulatory system?
D. Generalization
Guide question:
1. Identify the key parts of the circulatory system ;
2. Describe the function of each part of the circulatory; and
3. Explain how the circulatory works with the respiratory system.
EVALUATION:
1. What will happen if the heart has a small opening between the left and right
ventricle?(essay)
ASSINGMENT
1. Think of an interactive way on how to disseminate information on the diseases caused
by cigarettes .
