The document outlines a lesson plan that describes how light can act as both a wave and particle. It includes the objectives, which are to describe light propagation, differentiate the wave and particle models of light, and explain photon theory. The lesson proper involves a discussion bingo activity where students debate statements about the dual nature of light. An assessment asks students to differentiate the wave and particle models. The lesson aims to help students understand that light exhibits both wave and particle properties and to explain photon theory and how it relates to atomic spectra.

2. B. Time Allotment:
1 hour
C. Instructional Material:
 Chalk and Chalkboard
 Hand-outs
 Laptop
 Visual Aids
D. Teaching Strategy
 Discovery Learning- The teacher will let the learners discover the concept of
the different models of light.
 Revolving circles- The teacher will let the learners discuss and brainstorm the
concept of the models of light and they will choose one resource speaker to
discuss with the other groups about the models they have discussed.
 Discussion Bingo -the teacher will let the learners sharpen their understanding
the different models of light.
 Advance Organizer- the teacher uses graphic organizers to summarize and
differentiate the different models of light.
E. Key concepts
Corpuscular (or particle) theory of light by Isaac Newton
-stated that light consisted of particles that travelled in straight lines.
Wave theory of light by Christian Huygens
- Huygens argued that if light were made of particles, when light beams crossed, the particles
would collide and cancel each other. He proposed that light was a wave.
Electromagnetic theory of light by James Clerk Maxwell
-combined electricity, magnetism,and light.
Quantum theory of light
-combines the two major theories of light, suggesting that light does not always behave as a
particle and light does not always behave as a wave.
F. Process skills:
- Comprehend
- Differentiate
- Explain
- Apply
G. Values Integrations
 The learners will realize the importance of light and
 The learners will gain basic knowledge in understanding the concept of light.

3. Learning Activities/ Procedure
Teacher’s Activity Learner’s Activity
Preliminary Activities
“Good evening class!”
“Jessa Mae, kindly lead the prayer”
“Before you set, kindly pick up pieces of
paper, cellophanes and arrange your chairs
properly. Make it sure it is line, in columns
and in rows.”
“Good evening Sir Edsyl!”
Jessa Mae is leading the prayer.
Students pick up pieces of trashes and
papers and aligned their chairs.
Recalling
“Last meeting you have discussed the
concepts of reflection, refraction and
transmission of light. Anyone from the
class who can give a short recall about
those concepts?”
“Yes, Noemi”.
“Very good, Noemi.”
Motivation
“I want you to prepare ¼ sheet of paper.
Write your name, section and the date
today. We will be having a minute quiz
relay. What you are going to do is, I want
you to answer the raise question in just a
“Sir! Sir!”
“I have learned that both of Newton and
Descartes describe the emergence of light
in the prism.”

4. minute. Each member of the group are
required to answer, after the given grace of
time, he/she must pass the paper to the
other members and so on. Take note; no
words or phrase repeated. Are you ready
everyone?”
“The question is, What is light?”
After 5 minutes.
“Time is up everyone. Let us check your
work. I will call someone to read your
answer.”
“Very good! All of your answers are
correct! Let’s clap our hands.”
Presentation of Objectives
This evening, we are going to target the
following lesson objectives, I want you to
read the objectives,
1. describe the propagation of light,
2. differentiate the wave model of light
and particle model of light and
3. explain the photon theory of light.
LessonProper
“So based on our minute quiz relay a while
ago, what do you think our lesson for this
evening? Anyone?”
“Yes, Andrie”
“Yes Sir!”
Students answer the question seriously.
One member of the group read their
answers.
Students clap their hands.
Students read the target lesson objectives.
“I think Sir, it is something related to how
lights behaves and what are the properties
of light.”

5. “Very well said, Andrie.”
“Our lesson for today explains more on the
propagation of light and how it behaves in
a given medium, whether the lights acts as
a wave or a particle. I hope you read and
research in advance about this dual nature
of lights.”
“This evening we will be having an
activity called Discussion Bingo. It is like
a Debate that will test how sharp your
understanding base on the topic. Wherein
you have 4 cards; propose which one team
will formulate a statement base on the
topic; support which the opponent team
agrees the statement of the one team;
challenge which one team opposes the
statement of the opponent team and
question which one team throw a question
to the opponent team base on the topic.
Anyone of the members must cooperate
and have a sentiment regarding the topic.
In every good question, sentiments and
opinion will have a corresponding points. I
will be graded you individually. The
noisiest team will have a deduction of
points. Remember in every raise opinion,
questions and sentiments must be
presented concisely in just one minute. If
you hear the bell then that’s the time to
stop your sentiments.”
“Is all clear everyone?”
“Kindly count one to two and find your
group silently. Kindly prepare one whole
sheet of paper per group and write the
name of the members”
“Okey, let’s start. The first team to
propose is the group one…..”
Students listen attentively.
“Yes Sir.”
Students find their groupmates silently.

6. After 30 minutes.
“Congratulations everyone for a very nice
discussion. Thank you for your
participation. All of you got the perfect
score!”
Assessment
Kindly prepare ½ lengthwise and answer
the questions seriously. 4 minutes
Differentiate the wave model of light and
the particle model of light.
After 4 minutes.
“Time is up. Everybody pass your paper to
the front.”
Synthesis/Realization
“Anyone from the class, who can give the
summary and realization about our topic
this evening?”
“Yes, France.”
“Very good, France”
The activity went so good and all of the
students participate in the discussion.
Students clap their hands.
Students seriously answer the assessment.
Students pass their paper to the front.
“I have learned that during our discussion
bingo, that the light behaves in different
ways at some point it could be act as a
wave and some point it act as a particle but
over all, it opens up my understanding that
light is not just shining our lives but light
is a concept that needs to study further for
us to live brightly.”

7. Enrichment Activity
One whole short bond paper. Minimum of
225 words.
What is Photon theory of light and explain
how this theory accounts for the atomic
spectra does.
“Thank you so much everyone for lively
discussion and to your participation. Good
bye class!”
“Good bye and Thank you Teachers!”
