AIOU TEACHING PRACTICES READY MADE LESSON PLAN
FINAL LESSON PLAN 1
SUBJECT : Physics NO OF STUDENTS: 34
DURATION: 30 minutes CLASS: 10
Topic: RESISTANCE CONNECTED IN PARALLEL
GENERAL OBJECTIVES:
At the end of the lesson, students would be able
To know the use of resistance.
How it resist?
SPECIFIC OBJECTIVES:
● Define resistance?
● What is its unit?
● Why it is used?
TEACHING METHOD:
Lecturer method
AV AIDS:
White board, Board markers (blue, black), Textbook, Diagrams
PREVIOUS KNOWLEDGE TEST:
Students should know about:
How resistance is connected in parallel?
How we can tell that they are connected in parallel?
How can we find equivalent resistance?
ANNOUNCEMENT OF THE TOPIC:
● Today, we are going to learn about the RESISTANCE CONNECTED IN PARALLEL
INTRODUCTION:
Resistance is a device which oppose to the flow of current .It is represented by ‘R’
and its unit is ohm named after German scientist OHM, and symbol is omega , Greek
letter Ω. In parallel the resistance are connected in such a way that one end of all is
connected to positive terminal of battery and other to negative terminal of battery. In
parallel voltage is same but current divide means it drops across each resistor. The
power supply is also connected across resistors.
MATHEMATICAL FORM:
V=V1 = V2 =V3
I = I1 +I2 + I3
V= I Re
V=V1 = V2 =V3 = I Re WHERE (I + I1 +I2 + I3)
I1 + I2 +I3 = V/Re
V/R1 +V/R2 +V/R3 = V/Re where v=IR & V/R =I BY OHM’S LAW
Cancelling ‘v’ on both sides we have,
1/R1 + 1/R2 +1/R3 = 1/Re
In parallel the equivalent resistance is always less than individual value.
In general,
1/R1 + 1/R2 +1/R3 = 1/Re + ……….+Rn
EVALUATION:
What will be circuit diagram for parallel combination of resistance?
What will be the equivalent resistance formula?
Is equivalent resistance value is smaller or greater than individual resistance value?

FINAL LESSON PLAN 2
SUBJECT: Physics NO OF STUDENTS: 34
DURATION: 30 minutes CLASS: 10
Topic: SIMPLE HARMONIC MOTION (SHM)
GENERAL OBJECTIVES:
At the end of the lesson, students would be able
To know about knowledge of SHM
HOW does it work
Different example showing SHM
SPECIFIC OBJECTIVES:
what is SHM?
What is its formula for mass spring system?
What is Hook’s law?
TEACHING METHOD:
Lecturer method
AV AIDS:
White board, Board markers (blue, black), Textbook, Diagrams
PREVIOUS KNOWLEDGE TEST:
Students should know about:
What is relation between ‘a’ and ‘x’ ?
What is restoring force?
What is vibratory motion?
ANNOUNCEMENT OF THE TOPIC:
● Today, we are going to learn about the SHM
INTRODUCTION:
A special kind of vibratory motion is called simple harmonic motion. The to and fro motion of
body about their mean position is called SHM.
Example, the motion of mass attached to spring on horizontal frictionless surface, motion of
ball placed in bowl and motion of bob attached to string are example of SHM.
MOTION OF MASS ATTACHED TO SPRING:
If the spring is compressed or stretched through small distance ‘x’ from mean
position it exert a F on mass.
According to Hook’s law, this force is proportional to displacement ‘x’ .
MATHEMATICAL FORM:
Fα X
F = -KX
K = – F/X
Where k is spring constant.
By Newton’s second law
F = ma
Therefore, k = – ma/x
Or , a = – kx/m
a α –x
( negative sign means a and x are in opposite direction
RESTORING FORCE:
A restoring force always pushes or pull object toward mean position performing
oscillatory motion.
At mean position the total energy is KE and at extreme position the energy is
potential. The ‘a’ is always directed toward mean position. At mean velocity is
max and at extreme ‘v’ is min.
FORMULA:
Formula for calculating time period is
T= 2𝜋 √M/K
EVALUATION:
What is formula to calculate time period?
What is KE?
What is PE?
What is oscillatory motion?
