1. INNOVATIVE LESSON TEMPLATE
PRELIMINARY DETAILS
Name of the teacher:Lekshmipriya r Standard:8
Name of the school:Govt. P.V.H.S.S Perumkulam Date:
Name of the subject:physics Strength:
Name of the unit:Motion Duration: 40'
Name of the topic:Acceleration Stage:12+
CURRICULAR STATEMENT
Pupil develop factual knowledge, conceptual knowledge, procedural knowledge,
and meta cognitive knowledge on the concept of acceleration through
observation, experimentation, discussion and evaluation by group activities.
CONTENTANALYSIS
New terms: acceleration, retardation
FACTS : The velocity of a departing train from station goes on increasing
The velocity of a train approaching the station increases
The unit of velocity is meter per second
The unit of time is s.
CONCEPT
The rate of change of velocity is acceleration .
The unit of acceleration is m ∕s₂.
Negative acceleration is called retardation.
LEARNING OUTCOME

2. Enable the pupil to develop
1.Factualknowledgeon acceleration by
A) Recalling different daily life situations.
B) Reconizes that speed, velocity, time, acceleration are inter
related.
2 . Conceptual knowledgeon acceleration by
A) Explaining the concept of acceleration
B) Demonstrating it through acting
3. proceduralknowledge on acceleration by
A) Doing and observing activities based on acceleration
B ) Applying the information to new and unfamiliar situations
4. Meta cognitive knowledgeon acceleration by
Focusing on the concept that rate of change in velocity is called
acceleration.
5. Develop different process skills like observation , inferring,
hypothesizing, inferring and communicating.
6 . Develop a positive attitude towards science.
PRE-REQUISITES
Pupil know about velocity

Activity cards, observation sheet....

INTRODUCTION
Teacher enters the class and greet the
students. Teacher narrates an accident
which happened at her home the day
before. Teacher told that her sister came
fromkozhikodeyesterday. Shecame in
train .Itwas her firstexperience in train
.She was so excited with the journey. She
found that when train approaches the
station it’s velocity decreases and when
the train depart fromthe station the
velocity increases.
Do you know the secret behind this.Now
we can study somefact relate to this.
PRESENTATION
Activity – 1
Teacher arrangesome students for a
small drama. Select 6 students for play.
firststudent is given the role of distance.
Second student got the role of
displacement .Third studentgot the role
of time. Fourth studentgot the role of
speed and finally fifth student
acceleration.
Teacher take the players outside and
Pupil listen carefully

4. made the drama clear to them
Then asks the other students to listen it
carefully.
Distance and displacements are brothers.
Their common friend is time. Speed is the
friend of distance and time. Velocity is the
friend of displacement and time. They all
meet in a party. As they enjoying the
party there come acceleration.
Acceleration: HEY happy to see you all
here.
Distance: Hei , how are you?
Acceleration: Fine , Hey look you and
displacement are looking almostthe same
.Is you both are related?
Distance: Yes he is my brother .Actually he
is the measure of change of position of an
object in a particular direction.
Acceleration: Oho … that is you both have
same unit; metre.
Displacement: Yes, actually we look
almost samebut weare different in
calculation .But in one situation we both
have samereading. Can you guess it?
Acceleration: If an object travels fromone
place to another in a straightline then
distance and displacement will be same.
Distance: Yes you are right. meet our
common friend time.
Acceleration: I know him, I am also his
friend.
Displacement: Meet velocity. He is my
and times friend.
Velocity: Hei acceleration
Acceleration: OHO so you are
Pupil starts the drama
Pupil observecarefully
Pupil discuss in groups about the
ideas they got fromthe play and
writes it in the activity card.
Pupil listen to the teacher.

5. displacement in unit time.
Velocity: Yes and my unit is meter per
second
Activity 2
Teacher narrates the remaining portion to
the actors.
Distance: Also I and time havea friend
speed meet him.
Speed: Nice to meet you acceleration
Acceleration: Oho so you are distance in
unit time.
Speed: Yes and my unit is meter per
second.
Acceleration: So I think when distance and
displacement become same sped and
velocity looks same.
Speed: You get it. Actually we are related
to each other we are friends.
Acceleration: Oho… But the truth is that I
also havesome relation with you; is n’t
velocity?
Velocity: Yes, you are rate of change of
velocity.
Acceleration: HE he and my unit is meter
per second square.
Speed: What is this changeof velocity? I
can’t understand.
Velocity: That is the final velocity and
intial velocity
Acceleration: Yes as the final velocity is
less than intial velocity then I become
negative acceleration .that is retardation.
Speed: Is there any chance to see u both?
Acceleration: There is one chancewhere u
can see me and retardation
The play stats again
Pupil observecarefully
Pupil disscuss aboutthe points that
they got fromact and note it.

6. simultaneously when train approaches
the station velocity decreases at that time
I become retardation. When train depart
fromstation velocity increases at that
time I become acceleration.
Displacement: So we are all related
All of them: Hei all come our samefamily
that is MOTION.
The drama ends.
Teacher asks somequestions to students
• Is distanceand displacement
related?
• What is their unit?
• What is rate of change of
displacement in unit time?
• What is it's unit?
• What is rate of changeof distance
in unit time and it's unit?
• What is rate of changeof velocity in
unit time?
• Negative acceleration is known as
• What is it's unit?
Consolidation
Rate of changein velocity is called
acceleration
Unit of acceleration is meter per second
square.
Negative acceleration is called retardation
Review
What is acceleration?
What is the unit of acceleration?
What is retardation?
Yes,They are related.

7. Follow up activity
Brakes are applied suddenly to a racing
car, travelling at 50 meter per second. If
the car stops after 20 second, calculate
the retardation of the car.
