IV. PROCEDURES TEACHERS’ ACTIVITY STUDENTS’ ACITIVITY
PRELIMINARIES
 Before we start, everyone kindly stand In the name of the Father, and of
for a short prayer that will be lead by ___ the
Son, and the
Holy Spirit
Thank you_____ Amen…
So, good morning everyone
Good morning Ma’am
Before you take your seat, kindly pick
up all the pieces of paper or any trash
under your chair

Okay, you may now take your seats.

Thank you Ma’am
Before we proceed to our formal
discussion, class secretary do we have
any absentees today
No one Ma’am
Okay, good to hear that everyone is
here again today. Very good

A. ELICIT Now, let’s start!

Who wants to do a recap first before we
move on to our next topic? (student raised his
hands)
Yes?
Ma’am, last meeting we
discussed about the three phases
of
matter. The solid, liquid, and gas
Very good____.
Another one?

(some students will raise their

hands)
Yes___?
We also discussed the
characteristics of each and we
Wow! It’s very evident that you truly provided some example
learned something from our previous
topic.
Any questions or clarifications prior to
that lesson? Is it all clear?
Nothing Ma’am, all clear
Okay good. So now, let us have our first
activity called ‘WORD HUNT’
All you have to do is to find the hidden
words on the grid either, horizontally,
vertically, diagonally, backward, or
forward in a span of 2 minutes, then
write all the words that you found in
your notebook. The first five who will
get all the 5 hidden words will get a
prize, just raise your pen to indicate
that you found all the words already,
so find all 5 hidden words as fast as
you can. Okay?
Okay Ma’am
Good, you may start
 HIDDEN WORDS: CONDUCTION
CONVECTION
RADIATION
HEAT
TRANSFER

CONDUCTIO
N
Just put a check on the correct answers
that you obtained

Those 5 students who finished first,

you’ll have a prize.

Who got 5 points?

(some students will raise their
Very good everyone. Later we will tackle hand)
how these words are related to our topic

B. ENGAGE
so now, here’s our learning objectives.
Kindly read everyone

At the end of the lesson, the student

should be able to:

❖ Explain the concept of heat and the

three modes of heat transfer
❖ Perform experiments to observe and
demonstrate the effects of different
heat transfer modes on objects and
material
❖ Demonstrate curiosity and
enthusiasm for exploring heat
transfer phenomena through hands-
on experiments and demonstration
Okay thankyou everyone.

Now, let’s proceed to our next activity (students will volunteer)

called
‘DART BALLOON GAME’
I need 2 groups with 5 members each.
Who wants to volunteer?
Yes?
Okay thankyou.
I have here 10 balloons, 5 balloons each
side with corresponding jumbled letters
inside.
To make it even clearer here’s the full
mechanics
Kindly read everyone

• Form 2 teams consisting of five

members each
• Teams takes turn playing
• A player from the first team
throws a dart at a balloon to pop
it
• Once popped the player retrieves
the jumbled word inside the
balloon to earn points (the words
have different point value based
on difficulty). After unscrambling,
the player passes the dart to the
next team member
• If the players encounter difficulty
in unscrambling the word, they
can skip the word and proceed to
the next player.
• This continues until all team
members have taken a turn
• Each team will have 2 minutes to
finish the game
Is it all clear? Do you have a
question? so since no one is
raising their hand, so I assume
that you clearly understand the
game mechanics

So those 10 students who volunteered,

kindly join me here in front. (students who volunteered will come
Okay thankyou. in front)
So let’s start

(the game will start)

Okay time is up
 announce the winner)
C. EXPLORE Okay, another activity let us have video
analysis I have here a short video
showing different scenarios involving
heat transfer, later I will ask you what
you have noticed in each scenario for
you to gain an initial knowledge about
our next topic.

Is it clear? Do you have any question? None Ma’am, all clear

Okay, so here’s the video presentation.

Guide questions:
1. What is heat?
2. How do heat flows?
3. What are the three modes of heat
transfer? Explain each.

(after presenting the video)

Okay, going back to our guide questions. Ma’am, heat is the form of
energy that can be transferred
What is heat? Anyone?
from one object to another.

Okay very good____

Give___3 claps Mam it says in the video that

heat moves from higher to lower
How do heat flows? temperature.
Very good____

Give___3 claps (students will clap)

Ma’am it’s conduction,
For the last question, what are the three convection and radiation.
modes of heat transfer?

(students will clap)

Okay very good, give___3 claps

So later we will further elaborate your

answers.
D. EXPLAIN (LESSON PROPER)
*Discuss what is heat transfer

So let’s discuss what is heat transfer

What is heat? So, based from__ it is a form

of energy that transfer between objects.
 And heat flows from what? Is it from hot
region to cold or from cold region to hot
region?
From hot area to cold area Ma’am
Okay, Very good!

Anyone, again what is the three mode of

heat transfer?

Yes__? Conduction, convection and radiation

Very good
Conduction, convection and radiation

So what is conduction, based on the video

presented a while ago?
The transfer of energy through direct
Yes___? contact Ma’am

Okay, very good. So in what medium does In solid ma’am

conduction occur?
Precisely!
It is because the molecules of a solid
materials are tightly packed so the tendency
is that the molecules bumped with each
other easily that leads to transfer of heat
Ma’am when you walk barefoot on a
Who can give me an example of conduction? hot sidewalk

Okay, can you explain to us how do walking Ma’am when you walk barefoot on a
barefooted on a sidewalk an example of sidewalk, the heat from the surface
conduction of the road transferred to the soles
of your foot making it warm. And
because there is a direct contact
between two object
Very good! Good explanation as well

How about convection?

Ma’am convection is process by
which heat is transferred by
movement of heated fluid such as
Give me an example water

One example of conduction is the

transfer of heat from a coffee to the
spoon
Okay, very good
And radiation?
Ma’am the heat is transfer through
electromagnetic wave
Example?
Sun heating the earth
Very good, how do you say so?

Ma’am sun doesn’t have a direct

contact with the earth but the earth
was heated right? And it is because
of the electromagnetic wave in the
Very good. Very good everyone surrounding that carry the heat from
the sun to the earth
E. ELABORATE Okay now, let’s proceed to another activity.
 We will be having a simple experiment
regarding our topic today.
So last time I group you into three Yes Ma’am
groups right?

Okay so for group 1, we have,

___, ___, ___, ____, ____, ___, ____, and ___.
For group 2, we have, ____, ___, ___, ___,
and, ___.
For group 3, ____, ____, ___, ___, ___, and
___.
So now go to your respective group and
form a circle. I’ll give you 3 minutes for
conducting experiments and then 1-2
minutes for the presentation

Here’s the rubric for the presentation

(see below)

So for the first group, conduction.

The materials needed are:
Metal rod (copper or aluminum) Candle
or small heat source, Stopwatch or timer
The steps are; kindly read group 1
