I. OBJECTIVES Explain the properties of
sound.
A. Content Standards: The propagation of sound through
solid, liquid and gas.
B. Performance
Standards:
C. Learning Investigate the effect of temperature
Competencies/ Objectives: to speed of sound through fair testing
Infer how the
movement of particles
of an object affects the
speed of sound through
it.

IV PROCEDURES
A. Reviewing Previous Teacher’s Instruction: Teacher’s Instruction:
Lesson or Presenting Speed of sound may differ for
New Lesson in different medium (solids,
liquids and gas).
What medium does the speed
of sound travels fastest?
What medium does the speed
of sound travels slowest?
Looking into the position of
the particles, does it explain
why sound travels fastest in
solids and slowest in gas
sound?
B. Establishing a Purpose Question of the Day: Question of the Day:
for the Lesson Does temperature affect the
speed of sound?
C. Presenting Teacher’s Instruction: .
Examples/Instances of Do you love singing at the
the Lesson bathroom?
Have you ever wondered why
open field concerts are usually
held during night time?
D. Discussing New Student do the Activity 6
Concepts and Reflecting and refracting
Practicing New sound
Skills#1
E. Discussing New
Concepts and
Practicing New
Skills#2
F. Developing Mastery The students answers the guide
question found in Activity 6.
(Leads To Formative
Assessment 3)
G. Finding Practical Can you give another
Application of applications of sound
Concepts and Skills in reflection?
Daily Living
H. Making Generalization Reflection is usually described
and Abstractions about the as the turning back of a wave
lesson as it hits a barrier. Echo is an
example of a reflected sound.
Reverberations on the other
hand refers, to the multiple
reflecting or echoes in a certain
place. It happens in a small
roomnwith height, width and
length dimensions of
approxiantely 17 meters or
less. Echo sounding is another
application of sound reflection.
Refraction is also manifested
as sort of” bending of sound
waves”
I. Evaluating Learning Directions: Listen carefully.
Choose the letter of the correct
answer.
1. It is usually described as the
turning back of a wave as it
hits a barrier.
a. sound b. reflection
c. refraction
2. Manifested as sort of
“bending” of sound waves.
a. sound b. reflection
c. refraction
3. What happens to the sound
during daytime?
a. When the sun shines air near
Earth’s surface is cooler than
the air above then sound would
move from cooler region
towards hotter air above.
b. When the sun shines air
near Earth’s surface is hotter
than the air above then sound
would move from hotter region
towards cooler air above.
c. Neither a or b
4. What happens to the sound
During night time?
a. When the sun shines air near
Earth’s surface is cooler than
the air above then sound would
move from cooler region
towards hotter air above.
b. When the sun shines air
near Earth’s surface is hotter
than the air above then sound
would move from hotter region
towards cooler air above.
5. Refer to the multiple
reflections or echoes in a
certain place.
a. sound b. refraction
c. reverberation
J. Additional Activities for
Application or
Remediation
VI- REMARKS
VII - REFLECTION
A. No. of learners who
earned 80% in the
evaluation
B. No. of learners who
required additional
activities for remediation
C. Did the remedial
lessons work?
D. No. of learners who
continue to require
remediation
E. Which of my teaching
strategies work well? Why
did this work?
F. What difficulties did I
encounter which my
principal or supervisor can
help me solve?
G. What innovation or
localized materials did I
used/discover which I
wish to share with other
teachers?
