INSTRUCTIONAL OBJECTIVES:-
1) The students will be able to recall the parts which involves in respiration.
2) The students will be able to recognise the upward & downward movement of body.
3) The students will be able to cite illustration of Respiration process.
4) The students will be able to differentiate between Breathing & respiration.
5) The students will be able to draw respiratory system of human being.
CONCEPTS:-
Respiration in organism
1) Breathing
2) Respiration
3) Respiratory system
4) Respiratory system in humans.
PREVIOUS KNOWLEDGE:-
The students should have previous knowledge about
- The different body parts.
- Lungs
Breathing & Respiration

INSTRUCTIONAL MATERIAL:-
SET INDUCTION:-
ACTIVITY: Breathing exercise ( Inhaling & Exhaling)
DEVELOPMENT OF LESSON :-
ACTIVITY :- Dramatisation
Materials Required : Pipe, Red thread or wool, Flash Cards(3).
Charts:- Human Respiratory System
SEQUENTIAL TEACHING LEANING
ACTIVITIES
EXPECTED BEHAVIOURAL
OUTCOME
Teacher greets the students
Tr:- Good Morning Student
Tr:- I hope all of you are fine .
ACTIVITY-I
Teacher tells students to close eyes.
Tr.:- Students now you inhale & carefully observe the size of stomach?
Tr.:- When you exhale what happens to size of stomach
Tr.:- So when we breath in which gas we inhale ?
Tr.:- Which gas we breath out?
(Students also greets teacher ss:- Good morning Teacher. ss:- It becomes bigger ss:- It becomes smaller ss:- Oxygen ss:- Carbon dioxide

Tr.:- There are number of organs involved in this process. This makes up a system called respiratory system
Tr.:- What is the main function of respiratory system ? ss:- Allow exchange of gases
Tr.:- Very good
Tr.:- What do you think is breathing & respiration same process
STATEMENT OF TOPIC :-
Tr.:- So today in this class we are going to learn about “ Respiration in Organism “ ss:- No
DEVELOPMENT OF LESSON :-
Tr.:- First now let us see difference between breathing & respiration
Teacher performs activity i.e. drama to demonstrate respiration process.
ACTIVITY – I :-
Teacher call 5 students infront
Teacher give flash card to each one of them
Teacher makes one student as cell.
Other student one as oxygen intaker & other one as carbon dioxide.
Teacher gives following instruction :-
Observe activity carefully. ss:- Students observe carefully

Don’t make noise
Tr.:- Here you can see , All living organisms are made up of no. of cell . Each of these cells require oxygen to break down food & obtain energy.
Tr.:- What first person doing is that he is taking in oxygen, that is first step & through this pipe oxygen reaches to cell. Where series of chemical reactions occur, which help in release of energy.
Tr.:- When food is broken down, the reaction produces water & carbon dioxide.
Tr.:- The removal of carbondioxide is called as exhalation
Tr.:- What is breathing ?
Tr.:- What is meant by Respiration ?
Tr.:- Very good.
Tr.:- So from this activity we conclude that
Tr.:- The process of releasing energy from breakdown of food is called as Respiration
Tr.:- Breathing is process of intake of oxygen & giving out of air rich in carbon dioxide.
Tr.:- Respiration takes place inside the cells whereas breathing takes place outside cells ss:- It is process of intake of air rich in oxygen & giving out air rich in carbon dioxide. ss:- Is process of releasing energy from breakdown of
Food.

Tr.:- The number of times a person breaths in a minute is termed as breathing rate.
Tr.:- What will happen to breathing rate when we run or do exercise?
Tr.:- Very good. Adult human being at rest breaths in & out 15-18 times in a minute. During heavy exercise breathing state can increase upto 25 times per minute
Tr.:- Whenever a person needs extra energy, he/she breaths faster. As a result more oxygen supplied to cells. It speeds up breakdown of food & more energy is released. Therefore we feel hungry after physical activity.
Tr.:- Now let us see the respiratory system in ss:- It will increase human being
Tr.:- Teacher shows the chart
Tr.:- Now, we take in air from surrounding?
Tr.:- Very good. We take in air from nostrils.
Tr.:- It passes through nostrils into nasal cavity. from nasal cavity it reaches our lungs through windpipe.
Tr.:- Lungs are present in chest cavity. This cavity surrounded by ribs on sides.
Tr.:- A large, muscular sheet called diaphragm forms floor of chest cavity.
Tr.:- During inhalation, ribs move up outwards and diaphragm moves down. The increase space in chest cavity & air rushes into lungs,

lungs get filled with air.
Tr.:- During exhalation. what will happen to diaphragam?
Tr.:- It reduces size of chest cavity and air pushed out of lungs
(Keep your palm on abdomen, fell movement of abdomen what do you find? ss:- It will move upwards
This activity shows that:-
Tr.:- When diaphragm contracts, oxygen rich air is pulled into lungs, when diaphragm relaxes, carbon dioxide rich air is pumped out of lungs.
Teachers summarises what we have learnt today.
EVALUATION :-
Worksheet will be given to students ss:- When we inhale ribs move upward when we exhale ribs move down.
