CONTENT ANALYSIS
TERMS : Nostrils, Nasal Canal, Pharynx, Epiglottis, Larynx, Trachea, Lungs, Bronchus Rib, Pleura,
Thoraxic Cavity, Diaphram
FACTS :  All living beings have a respiratory system
 The respiratory system extends from the nostrils to the lungs
 The body obtains oxygen when atmospheric air passess through the respiratory system.
 Lungs are the respiratory organ in humans
CONCEPTS
Major concept
All living beings have respiratory system

3. Minor concept :
 The respiratory system extends from the nostrils to the lungs
 The part of the respiratory system are nostrils, nasal cavity, epiglottis, Trachea, Bronchi, Lungs,
Pleura, Bronchioles, Alveoli.
 Nostrils are opening through which air enters the body.
 Nasal Cavity opens into the pharynx
 The oesophagus and Trachea start at the pharynx
 Trachea made up of incomplete rings of cartilage
 Bronchi opens into a lungs on each side
 Two lungs are found on either side of the heart in the thoracic cavity
 Pleura is a double membrane covering the lung
 Bronchioles are the branches of bronchi
 Each bronchiole ends in a group of alveoli
PRE-REQUISITES
 Lungs are the respiratory organ
 All living being have respiratory system

b. Pupil are able to solve problems

6. SYNTAX
PHASE TEACHER ACTIVITY PUPIL ACTIVITY
Why do we get food?
You have learnt that energy for life activities is
obtained from food?
Do you know energy is not made available just
because nutrients teach the cell?
Do you know that Oxygen is also needed to release
energy from nutrients?
If so shouldnot Oxygen also reach the cell, why?
Yes, you heard about lungs?
Which is the respiratory system in humans
Food gives us energy to do work.
Yes
Yes
Yes
Yes. The body gets O2 when the
atmospheric air passes through
respiratory system.
Yes
Lungs

7. Today we are going to the study of respiratory
system in humans (B.B)
Phase I
Warm up the groups
We have seen about the structure of lungs. Do you
understand the parts?
How respiration occurs?
The respiratory system extends from the nostrils to
the lungs.
Yes
through lungs
Make the problem
explicit
What do you know about respiratory system Respiratory system extent from
nostrils
Interpret the issue Teacher and pupil sharing and discussing the
knowledge about respiration in lungs
Pupil sharing when they have
learned before.
Explain the role play Today we are going to learn about the respiratory
system from the nostrils to the lungs through a
dramatic representation.
Pupil actively listening.

8. Phase II
Select participants
Teacher asking students to act as the respiration
from nostril to the lungs each on should play the
role of nostril, nasal canal, pharynx, Trachea,
Bronchi, Lungs bronchiole and act accordingly
Phase III
Set the Stage
Teacher giving the proportion to each one.
Teacher explains when to start, how to start, where
to start to the pupils.
Pupil listen carefully
Phase IV
Prepare the observers
To other pupil teacher explain how to observe the
play, respiration from nostrils to the lungs the
main organs are responsible to this process and
their peculiarities.
Pupil listen carefully
Phase V
Enact
Pupil acting their role which they got they
discussing with each other about the roles to be
played, pupil playing their roles. Teacher help
them.
Other pupil listening and observing
the play.

9. Phase VI
Discuss and Evaluate
Teacher giving feedback about the role play.
Teacher inquiry other pupils how much they have
understood. Teacher discussing with the pupil.
Teacher advising to act more better than before.
Pupil discussing
Phase VII
Re-enact
Teacher ask to repeat the play again All pupil observing the roles and
understanding
Phase VIII
Re-discuss and
evaluate
All discussing about the role play again and
evaluating
All pupil participating in discussion
Phase IX
Share experience and
generalise
Pupil understanding the respiration from nostrils to
the lungs and their peculiarities in each organs.
Teacher explain again discussing and summarizing
Pupil listen carefully
