Okay you may now take your seat!

Attendance: So, who are absent for today?

Classroom Rules:
Please be guided with these gentle class
rules:
1. Make sure you have everything you need
before starting.
2. Everyone deserves respect both students
and teachers.
3. Raise your hand to talk.
4. Show respect for school and personal
property.
5. When someone else is talking, listen.
6. Do not talk when somebody is talking.

Are all these rules clear?
Okay, very good! I hope that you will follow
all of these class rules.

Review: “Ok, class, before we proceed to
our new lesson. Let us have a short review
with the lesson that we discussed last week.

Good!
So, what are the colors present in sunlight?
-Good morning Sir!

(One of the learners will raise his/her
hand to lead the prayer.)

-Thank you Sir!


-(Somebody will announce the names of
the learners who are not around)















-Yes Sir!




-Our topic last week is about
characteristics of light Sir!













Objective 5
Safety policies and procedures
(Establish safe and secure learning
environment to enhance learning through
the consistent implementation of policies,
guidelines and procedures)

3. Yes, Johannah Feb!

Very good! Last week we have discussed about
Light and its characteristics.

Motivation: Now, let us have an activity.
And this activity is titled “Guess the
Sound”.
What you are going to do is listen to the
sound and guess the object that makes the
sound. You have choices to choose from.

Are you ready?

What’s the answer in number 1?
Very good!
Number2?
Very Good!
….
(The allotted time for this activity is 5
minutes)

Base on our activity, what do you think will
be our topic for today? Can you guess it?

Good!
Our topic for today is about “Characteristics
of Sound”



-Red, Orange, Yellow, Green, Blue,
Indigo, and Violet Sir!









-Yes Sir!

-Letter A Sir!

-Vacuum cleaner Sir






-Possible answers:
-Sound
-Types of Sound
-Characteristics of sound.





Objective 2
Used a range of teaching strategies that
enhance learner achievement in literacy
and numeracy skills.
B. Establishing a
purpose for the lesson


Reading of lesson objectives:

Objectives:
a. define sound
b. appreciate sounds within their
surroundings.
c. apply the properties of sound using
different materials for an emergency
situation.

4. C. Presenting
examples/instance of
new lesson

(ENGAGE)
Unlocking of difficult words:
 Amplitude - the maximum displacement
or distance moved by a point on a vibrating
body or wave measured from its equilibrium
position.
 Wavelength - the distance between
identical points (adjacent crests) in the
adjacent cycles of a waveform signal
propagated in space or along a wire.
 Velocity - a vector expression of the
displacement that an object or particle
undergoes with respect to time.
 Pitch - refers to highness and lowness of
sound.
 Loudness - how soft or how intense the
sound is as perceived by the ear and
interpreted by the brain.

Sound
is more distinct in solids than in any other
medium. It is louder than that of in liquid
and in gas. It is because the particles of a
solid are more compact than that of liquid
and gas. This allows for sound to travels
fastest in solid and slowest in gas.

The table shows the speed of sound in
different media:

2.He (0

CHARACTERISTICS OF SOUND
1.Pitch and Frequency(f)
Sound frequency is the number of sound
waves that passes through a point in a
certain amount of time, such as one second.
The frequency is related to the pitch of a
sound which is defined as the perception of
highness or lowness. The faster the sound
waves move, the greater the frequency and
the higher the pitch. The hertz (Hz) is a unit
to measure frequency and so pitch is
measured in hertz.

Another characteristic of wave which is
related to the pitch of a sound wave is the
wavelength. The minimum distance in
which a sound wave repeats itself is called
its wavelength.

2. Loudness and Amplitude (A)
The amount of energy a sound wave carries
is known as intensity of the sound. Loudness
is a psychological sensation that differs for
different people and it is related to the
intensity of sound. So, the loudness of a
sound is determined mainly by the
amplitude of the sound wave.

Sound cannot travel in a vacuum.
Remember that sound is a mechanical wave

6. D. Discussing new
concepts and practicing
new skills #1
(EXPLORE)
Group Activity: MAKE YOUR
SOUND!
Instructions: The class will be grouped
into 3, you will create your own sound out
of the materials inside the classroom.
(Clapping and the use of voice is allowed).
They will be given 10 minutes to do the
task. You will be rated through a rubric.

I hope everyone will cooperate with your
group so that you will have an impressive
outcome and your task will be finished on
time.

Is it clear?

Rubrics in Rating Group Tasks
CREATIVITY
(The kind of materials they used) - 5%
ORGANIZATION
(The clarity of sound) - 5%
TEAMWORK - 5%
TOTAL 15%

















Yes Sir!
Objective 3
Applied a range of teaching strategies to
develop critical and creative thinking, as
well as other higher-order thinking skills.




Objective 6
Maintained learning environments that
promote fairness, respect and care to
encourage learning.
E. Discussing new
concepts and practicing
new skills #2

F. Developing mastery
(Leads to formative
assessment)

(EXPLAIN)
1. In your activity, you have observed that
sound is produced by singing, clapping,
using lyre, or drum. The vibrations created
by clapping or singing produced the sound.
This also shows that?

2. Sound is more distinct and louder when in
what medium? Why

Sound can be heard /travels through
different sources / media.




In solid. It is because the particles of a
solid are more compact than that of
liquid and gas. This allows for sound

7. 3. You have observed that each material
you’ve used has different sound created.
Sound has properties which are pitch and
loudness. What do you think is the
difference between this two?
to travels fastest in solid and slowest
in gas.

Pitch refers to highness and lowness
of sound.
G. Finding practical
applications of concepts
and skills
In this present time, environmental problems
are one of the major disasters that affects
our community. To inform everybody on the
coming disaster, people created loud sounds
from different things in order to produce
sound with larger amplitude, longer
wavelength and faster velocity. As a student,
you must be prepared in order to make
yourselves and others safe.
What are those things or object that can be
used as an early warning device considering
a loud sound must be produced?

Very Good!
Objective 1
Applied knowledge of content within and
across curriculum teaching areas.
(Environmental Science/ DRRM)
H. Making
generalizations and
abstractions about the
lesson
(ELABORATE)
Now, who can give another importance of sound
in our daily living?


Very Good!
Possible Anwer/s;
Sound plays an essential role in our
subsistence: it informs us of the nature,
objects and actions. We communicate by
using our ears to hear every sound.

8. I. Evaluating learning
(EVALUATION)
Direction: Arrange the following materials
where sound can travel the slowest to the
fastest, 1 as the slowest and 8 as the fastest.

remediation
(EXTEND)
Direction:
Answer the following questions completely.
Write your answer in the space provided.
1. Which would best transmit sound: steel,
water, or gas? Why?
2. If you are in space, are you capable of
listening to another spaceship approaching
you? Why or why not?

Is that clear?
Any question or clarifications?

I hope you learn a lot from this session.










Yes Sir!
None so far Sir!

9. Okay, so before we leave the classroom,
kindly pick pieces of paper and arrange your
chairs.
Okay, class, that’s all for today, and
Goodbye!





Goodbye! And thank you Sir!
