Classroom Management/ Preparation
a.1 Opening Prayer
Let us all stand for a prayer.
Good afternoon, class.
Students’ Activity
The students stand for a song
prayer. Good afternoon, Ms.
Legaspi, It’s nice to see you again.
Thank and you students, you may now
take your sit.”
a.2 Cleanliness and orderliness
Kindly, pick up pieces of papers
under your chairs and throw it to the
garbage bin.
(The students pick up the pieces of
papers under their chairs and throw to
the garbage bin.)
a.3 Checking of Attendance
How are you today class?
Who are absent today?
Very good!
Fine, Ma’am.
None, Ma’am.

Motivation
To start our lesson and reveal our topic for today, let’s
have an ice breaker game. A combination of 4 pics 1 word
and Pinoy henyo inspired game. Are you ready?
Yes, Ma’am.
Part I. Games [PictuART Henyo]
How to play the game?
Teacher will group the class into two. The teacher
selects two students, one to be the "gesturer" for the
game and the other to be the “guesser”.
• The teacher shows the "gesturing" student the card. The
student gestures or acts out the card without making
any sounds. The “guesser” must predict the word with
the help of slide presentation (4pics one word) and by
the gesture of his/her co-presenter. They will have two
minutes guessing.
• The winner will gain smiley chips with corresponding
points.
•
Did you understand the instructions, class?
Yes, Ma’am.
Rules for Playing PictuART Henyo
• No words. No pointing at objects in a room. No lip
movements.
• Only "acting out" words or pantomiming similar
sounding words.
• Two teams play against each other and divide an equal
amount of cards between them.
• A card with a phrase of Team 1 is revealed to one
person (gesturer) of team 1 and kept secret from the rest
of the team, guesser must guess their gesturer act.
• No guesser/gesturer may guess/act more than once for
the team members had a chance to be the gesturer and
guesser.
• The actor has a limited time (2 minutes) to act out the
phrase to the guesser.
• The gesturer can make any gestures to act out the word.
• You may not make any oral utterances. You may make
other sounds such as clapping, but you can't use your
voice to moo like a cow.
• You may not mouth words such as "Ho ho ho" for
Santa Claus, or draw letters in the air, or anything like
that that would reduce the game to a mindless exercise
in patience.
Did you understand the rules, class?
Yes, Ma’am.
Part II. Miniature Observation
The teacher will project a video on the front. The
students will have to observe the video presentation.
After observing, the teacher will ask the following
questions to the students.
1. What are the things that you see in the miniature
from the video presentation?
2. What did you observe with those things?
The Students answer may vary.
3. How can you relate that scenario with the real
thing on our National Roads?
Presentation of the Topic
Now, do you know the things behind that scenario?
Those are the electronic components.
Do you know what is meant by electronic components?
Electronic component refers to any basic discrete
device or physical entity in an electronic system used to
affect electrons or their associated fields.
These are basic electronic element or electronic
parts usually packaged in a discrete form with two or
more connecting leads or metallic pads.
Today, we will discuss and tackle the basic electronic
components, circuit construction, working and its
application.
Are you ready?
Discussion
Let’s go over to our lesson. I will introduce to you the basic
electronic components that we will working out later.
Light Emitting Diode (LED)
 A particular type of diode that convert electrical energy
into light.
 It is a two-lead semiconductor light source. It is a p–n
junction diode, which emits light when activated. When
a suitable voltage is applied to the leads, electrons are
able to recombine with electron holes within the device,
releasing energy in the form of photons.
Resistor
 An electrical component that limits or regulates the flow
of electrical current in an electronic circuit.
 It is a two terminal device have one connection on each
of its sides. Two common resistor symbols are shown in

.
Yes, Ma’am.
given figure; one is in American style (zig zag line) and
other is international style.
Light Dependent Resistor (LDR)
 A resistor whose resistance decreases with increasing
incident light intensity; they are used in many consumer
products to determine the intensity of light.
Transistor
 A transistor is a semiconductor device used to amplify
and switch electronic signals and electrical power.
Those are some of the widely used electronic components.
For it to function, there must be a supply of current. So what
We must use a battery.
shall we use?
Battery
 It has more than a cell and is used for the same purpose.
The smaller terminal is negative and the larger one is
positive. Abbreviated as ‘B’.
Understood, class?
Yes, Maam.
For us to test the integrity of a circuit, we will be using a
breadboard.
Who among the class know about a breadboard?
Breadboard,
 Also called a proto-board, is a reusable platform for
temporarily built electronic circuits.
Do you understand everything about the breadboard? On
how to use it?
The Students answer may vary.
Very Good!
So, for better understanding of the lesson, let’s have a
hands-on activity.
I will group you into three (3). You will be constructing a
circuit using a breadboard.
I will give you 10 minutes to finish your work. After ten
(10) minutes we will check your work.
Did you understand the instructions, class?
Yes, Ma’am.
Then, as you have your group activity take note of the
following rubrics:
Everyone will follow the teacher’s
instructions.
The students will work quietly.
After 10 minutes, the students should be done with their
hands-on activity.
Now, let us check your work.
Good Job Class! You’re truly amazing.
Generalization
Now based on our lesson class, what is the importance of
knowing the functionality of those components?
Having knowledge of the functionality of components, The Students answer may vary.
make it easier to make an electronic circuit without
damaging it.
How about a breadboard? Why breadboarding is
important?
It is imporatant because it is used to build and test circuits
quickly before finalizing any circuit design.
It seems that you understand the lesson.
Now be ready for a quiz, kindly get your pen. I will be
providing you worksheet.
