Good morning class!
Good morning, ma’am.
Did you eat your snacks?
Yes ma’am.
Before we start our lesson, kindly stand and (Students will pray)
let’s pray.
Arrange your chairs and kindly pick up those (Arrange their chairs and pick
pieces of papers and plastics under your up pieces of paper and
chairs.
plastics under their chair.)
You may now take your seats.
Thank you ma’am.
Secretary in each group, who is absent?
(Secretary in each group will
report who are absent in their
group)
As we go on with our lesson for today,
please be reminded with our classroom rules.
A. Reviewing Previous
Lesson or Presenting
the new lesson.
Light is a electromagnetic
wave which means that it
doesn’t need a medium to
propagate.
Light travels in a straight
path.
Light is a form of energy
made of photons.
B. Establishing a purpose
for the lesson.
It will become hot ma’am.
It will become hot also
ma’am.
Last meeting we learned about light. What is
light?
Very good. Light is an electromagnetic wave
and it is a form of energy made of photons.
Photons is the smallest unit of visible light.
What do you think will happen to the pan on
the top of the stove?
How about to the metal spoon? What do you
think will happen if I leave it in the pan with
water?
Let’s check if your answers are correct as we
go on with our discussion.
C. Presenting examples /
EXPLORE:
instances of the new lesson. Let’s have a game. Find a partner and
arrange the jumbled word. Base your answer
to the given definition and write it in a 1/4
sheet of paper.

D. Discussing new
concepts and practicing
new skills #1.
Answer key:
1. Convection
2. Conduction
3. Radiation
EXPLAIN:
Based on the game we’ve done, what do you
think is our topic for today?
Heat transfer ma’am.
Very good. We are going to learn about heat
transfer.
Let’s watch the video. After watching the
video, answer the questions.
Conduction -Convection- Radiation-Heat Transfer.mp4
Questions:
1. ________ is the transfer of energy from
objects of different temperatures.
2. _________ measure the kinetic energy.
3. As the temperature increases, the energy
________.
4. ______ is a process in which the transfer
of heat takes place between objects by direct
contact.
5. _______ is the heat transfer by movement
of a fluid.
6. _______ is when heat transmitted without
any physical contact.
7. Burning paper is an example of _______.
8. -10. Give the 3 methods of heat transfer.
A. Developing mastery.
(Formative Assessment)
Answer key:
1. Heat
2. Temperature
3. Increases
4. Conduction
5. Convection
6. Radiation
7. Convection
8. Conduction
9. Convection
10. Radiation
For us to better understand the concept of
heat transfer, we will have an activity.
Instructions:
1. Go to your group area.
2. Perform the activity and answer the
following questions.
Procedure:
1. Fill the cup with hot water.
2. Put the two spoons (Metal and Plastic)
into the mug.
3. Arrange the spoons properly. Their handle
should not touch one another.
4. After five minutes feel the handle of each
spoon. Try to observe which spoon still feels
hot and which spoon already feels cold.
Directions: Answer the following questions
based from the given activity you performed.
Write your answer on a 1/4 sheet of paper.
1. Compare the two spoons, then determine
which of them becomes hot first?
2. What type of object/s felt warm?
3. Which spoon is hot even though the
handle is not submerged in the boiled water?
4. How do you differentiate a conducting
materials from non- conducting materials?
B. Finding practical
applications of concepts
and skills in daily living.
Answer key:
1. The metal spoon.
2. Metal objects
3. Metal spoon
4. Conducting materials are low resistivity
materials, which conduct heat as well as
electricity while non- conducting materials
are those can’t conduct electricity.
ELABORATE:
Let’s have an activity called FIXED ME.
Instructions:
1. Stay in your group and arrange the (Student will perform and
jumbled word.
observe the activity)
2. Give example of the word.
(Example: Heat is the word and example of
heat is sun.)
C. Making generalizations
and abstractions about the
lesson.
To sum up our lesson, what is heat?
Very good. There are three methods of heat
Conduction, convection and
transfer, what are they?
radiation ma’am.
Correct. What is the difference of conduction Conduction is a process in
to convection?
which the transfer of heat
takes place between objects
by direct contact while
convection is the heat transfer
by movement of a fluid
ma’am.
Very good. Radiation is when heat
transmitted without any physical contact. Do
Yes ma’am.
you get it class?
D. Evaluating learning.
EVALUATE:
Bring out 1/4 sheet of paper and let’s have
a quiz.
Directions: Write FACT if the statement is
TRUE and BLUFF if the statement is
FALSE.
1. There are four methods of heat transfer.
2. Conduction is a process in which the
transfer of heat takes place between objects
by direct contact.
3. Radiation is when heat transmitted
without any physical contact.
4. Conduction is the heat transfer by
movement of a fluid.
5. Heat is the transfer of energy from objects
of different temperatures.
Answer key:
1. BLUFF
2. FACT
3. FACT
4. BLUFF
5. FACT
E. Additional activities for
application or remediation.
List down examples of conductive,
convection and radiation materials.
