A Detailed Lesson Plan in Science 10
I. Objectives
At the end of the lesson, the students will be able to:
observe the deflection of a galvanometer needle when a magnet moves inside a
current-carrying coil.
identify and explain the factors that affect the induced current through a
conductor.
appreciate the importance of electromagnetic induction.
II. Subject Matter
A. Topic: PRINCIPLES OF ELECTROMAGNETIC INDUCTION
B. Reference: Grade 10 Science Learner’s and Teacher’s Material and Internet
C. Instructional Materials: PowerPoint presentation, television, simulation.
III. Procedure
Teacher’s Activity Student’s Activity
A. Preparatory Activities
“Good Morning Class…” “Good Morning Sir!”
“Please stand up and let us Pray first…” (one student will lead the prayer)
Is anyone absent today None sir
“Very Good”
Before we proceed to our lesson this
morning let’s first have our review.
What is our topic last meeting? Our topic last meeting is all about
Magnetic Field Around Current-carrying
Conductors
Exactly.
Who discovered the magnetic field Hans Christian Oersted
around a wire carrying current?
You’re correct.
What happens when you place iron filling The Iron filling arrange them itself in form
to the conductor?
of magnetic field.
Well done
Why current carrying conductor produces Moving charges generate a magnetic field,
magnetic field? and the current in the conductor consists of
moving charges.
Very good answer
Now, Are you ready for our new lesson? Yes sir!
B. Developmental Activities
Motivation
Before we proceed to our new lesson, I Yes sir!
have here a video clip about our lesson (The students will watch the video and
for today. Please take note the important take note about the important details).
details.
(Video Presentation)
Presentation of the lesson
Based on the video presentation, what do Based on the video presentation our topic
is all about Faraday’s law of
you think our lesson for today?
electromagnetic induction.
Very Good!
Discussion
What does Michael Faraday discovered? Michael Faraday discovered
electromagnetic induction.
Good answer!
What is electromagnetism? Electromagnetism is one of the ways that
electricity & magnetism are connected.
Nice answer
Activity
For the activity for today we will focus The student answering the activity while
on the Faraday’s law of electromagnetic the teacher uses the simulation.
induction. List the following materials
used in the simulation and observed the
procedure of the experiment and answer
the following activity on page 123. The
table 10
Generalization
What happened when the magnet with The Galvanometer turns left.
north pole enters the coil?
Good Answer!
What happened when the magnet with The Galvanometer turns left.
north pole exits the coil?
Exactly!
Does the size of the coil affect the flick of Yes because as I observe the smaller coil
the hands of the galvanometer? Explain flicks weak than the larger coil
your answer.
Very good!
Application
The electromagnetic induction has much Speed control technology.
use in our daily lives. Such as technology
these days used electromagnetic
technology to function. Please kindly
give one technology that uses
electromagnetism.
Yes good answer and what is the use of To ensure road safety and minimize
speed control technology? vehicular-related death, buses, and other
public utility vehicles can be equipped
with a speed control device that limits the
maximum speed by using electromagnetic
brakes in combination with a motor once
the limit is exceeded.
Nice answer. Give another technology Traffic Light
that uses electromagnetism.
Good answer and how traffic light Vehicles waiting at intersections with coils
works? buried underneath are within an
electromagnetic field. Changes in the field
activate the traffic light as programmed.
Very good explanation. Give last one Induction Cooker
example of technology that uses
electromagnetism.
Good answer. Induction Cooker is the In induction stoves, current flowing
very good example of technology that through the copper coil wound underneath
uses electromagnetism. And how does the cooking surface produces an
Induction Cooker works? electromagnetic field small enough to
surround the base of the cooking pot.
Very good answer and this is why food
cooks faster when heat is conducted
directly and almost entirely at the base of
the cooking pot.
IV. Evaluation
Teacher’s activity Students’ activity
Pls. get ¼ sheet of pad paper and we will (The students will follow)
have a short quiz. Identify the following.
Please listen carefully to the question. I
will read the question twice.
1. This relates the electricity and
magnetism?
2. He discovers the electromagnetic
induction?
3. – 5. Give three technologies that use
electromagnetism.
V. Assignment
For your assignment please make an essay on how technology uses electromagnetism helps
our society.
