2. A.Reviewing previous
lesson or presenting the
new lesson
Differentiate Kinetic from
Potential Energy.
What is a sound wave?
How is sound produced?
B.Establishing a purpose
for the lesson
Guessing game:
Let the students guess the
answer to the question, “What is a
vibration produced by a vibrating
body”. They may decode the term
by dialing the numbers 76863, in
the keypad below.
How do you communicate to your
love ones miles away from you?
C.Presenting
examples/instances of
the new lesson
Why do sound vibrates?
Do you think it travels through
space?
If you flock the string of the guitar
one by one how do the sound
differs?
D.Discussion of new
concepts and practicing
new skills #1
Do the activity on Sound,

Sound, Lesson Guide G-8 First
Quarter pp. 55-56
E.Discussion of new
concepts and practicing
new skills #2
Analysis:
Q1. What is the purpose of
tapping the tuning fork to a wood
or rubber sole?
Q2. What causes sound?
Q3. What happens to the
loudness as you move the tuning
fork from up and down?
Q4. Can sound be transmitted if
there is no matter to form a
medium?
Analysis:
Q1. What happens to the other
colored beads when the blue bead is
tapped?
Q2. Is there an occasion when the
beads converge then expand?

wave determines the pitch of a
sound?
F.Developing mastery
(Leads to Formative
Assessment 3)
(Discuss the answers in the
activity given.)
(Discuss the answers in the
activity given.)
G.Finding Practical
applications of
concepts and skills in
daily living
How do you know that there is
an approaching train? If you
are living near a railway, how
does it affect your emotion?
Why are sound important in:
Communication
Signaling system
Music
H.Making generalizations
and abstractions about
the lesson
Sound waves are produced
by vibrating objects. They
are propagated through a
medium from the source.
Sound waves are
longitudinal waves.
Particles of the medium
vibrate in the direction of
wave motion.
The material through which
sound travels is known as the
medium.
The medium can be a solid,
liquid, or a gas.
Sound needs a medium to
travel. It cannot travel through
vacuum.
I.Evaluating learning
Direction: In a ¼ sheet of paper, write
TRUE if the statement is correct and
FALSE if otherwise.
1.Sound is a mechanical wave
propagating in space.
2. Sound does not need a medium to
propagate.
3. Sound wave is a longitudinal wave.
4. Particles of the medium vibrate in
the direction of wave motion.
5. Sound carries energy.
Direction: In a ¼ sheet of paper,
write the letter of the correct
answer.
1. Sound is an example of
*A. a longitudinal wave.
B. a wave that can travel through a
vacuum.
C. a transverse wave.
D. a wave that does not transmit
energy.
2. When sound travel through air,
the air particles_______.
*A. vibrate along the direction of
wave propagation
B. vibrate but not in any fixed
direction
C. vibrate perpendicular to the
direction of wave propagation
D. do not vibrate
3. Sound is produced due to
_____.
A. circulation *C. vibration
B. friction D. refraction
4 Sound passes from one place to
another in the form of
A. Rays C. energy

4. *B. waves D. light

5. Sound waves have _____.
A. amplitude only
B. amplitude and wavelength only

application of
remediation

Define the following
characteristics of sound:
• Frequency
• Amplitude
• Pitch
• Loudness
• Intensity
• Speed
(Write it on your notebook.)
