Measures of Dispersion and Variability: Range, QD, AD and SD
Innovative lesson plan
1. INNOVATIVE LESSON PLAN
I think the usual lesson plan used for teaching is not much easy for analyzing. For easy, I actually reset the
format of the lesson plan into my own. So here I publish the format of such an easy lesson plan with something
different on the physics topic CENTRE OF GRAVITY. And I think it is essential for including the curricular
statement and content analysis with it
2. Subject : Physics Standard : IX
Unit : Gravitation Duration : 45
Sub unit : Centre of gravity Date :
CURRICULARSTATEMENT
Pupil develop knowledge on the topic through observation and group activity
CONTENT ANALYSIS
Terms : centre of gravity, stable equilibrium, unstable equilibrium, neutral equilibrium
Facts : a cone stands with its base has stable equilibrium.
The bus will be unstable when large numbers of passengers stand on the upper deck
Concept : Every object has a fixed point through which the weight of the bodyis assumed to act.
Focus : To develop scientific process skills like observations, questioning, communicating, processing,
inferring etc on the topic
Previous knowledge:pupils already know the conceptof weight
Supporting items: notebook, stick, metric scale, card boards, cylinder, flat bottomed bottle
3. Topic
Daily life usage
Grouping
Instruction
Centre of gravity
Play with balancing books at a single point
Divide the pupils into group
All pupils must write the points you got for the present class on your science dairy
Activity Items and classroom settings Conclusion
1.centre of gravity
Items:
Notebook, stick, metric scale
Settings:
Mark balancing points in each
items
Write and read observations
Every objects has a fixed point through
which the weight of the bodyis
assumed to act in the centre of gravity
4. 2.finding the centre of
gravity
Items:
Card board with different shapes,
string, hanger, a weight, bangle
Settings:
Hang cardboard with string in
different positions
Find the point if coincidence of
string
In certain objects the centre of gravity
will be outside and certain have inside
the material of the object
3. equilibrium position Items :
Cylinder, cardboard
Settings:
Find different positions of cylinder
Write the different stability of
cylinder
Stable Equilibrium
Unstable equilibrium
Neutral equilibrium
4. centre of gravity and
equilibrium
Items:
Flat bottomed bottle (specially arranged)
with string setted in a cardboard
Settings:
Change the position of bottle by
cardboard
The object will be at equilibrium when
the centre of gravity is within the base
are of the object and surface
5. Notice the position of string
Identify the string and stability of
the bottles

Physics
Centre of gravity
- A fixed point
Equilibrium
- Stable Equilibrium
- Unstable Equilibrium
- Neutral Equilibrium
6. Pupil observations : teacher ask some pupils from each group to consolidate the topic
