d. Setting of Standards
Class monitor, who is absent today? Please
list down who is absent for this afternoon.
And mark absent also for those students
who are not in their proper chair.
Now class, what should a good student do
when the teacher is discussing her in front?
What else!
Ma’am sit properly
and no extra
movement.
Keep quit
ma’am.
This time class let me introduce to you our
classroom rules.
Everybody read.

Classroom Rules
Treat others with respect at all
times.
Listen to the teacher when s/he
speaks.
Ask for help when you need it.
Be prepared every day with
required items.
Respect other people's
property.
Listen and follow directions.
Raise your hand before
speaking or leaving your seat
Can I expect all of that from you class?
Yes ma’am.
Very good!
This is a reminder for everyone to please
pass your output on or before the deadline
to get the proper credit for
your work, Okay?
We understood
ma’am.
e. Review Previous
Lesson
Last meeting we discussed about the
Phase Change of Matter.
Now, who can recall the different changes
taking place when matter changes its state?
Is there any question or clarification
regarding to our last topic?
(Students’
answers).
None ma’am
Very good!
B. Presenting New Lesson
( 7 minutes)
a. Motivation
Before we proceed to our lesson today,
group your selves into five groups. The
same group we had yesterday.
Our activity is called “Who Am I?”. Now,
I’ll show you pictures or phrases.
Just raise your hands if you know the

answers.
Does anyone from the class have a
question?
Okay, is everyone ready?
None ma’am.
Yes, we are ready!
Let us start then.
b. Presentation of the
Lesson
From the activity, what do you think is
our topic for today?
c. State the objectives
of the lesson
That’s right. Our topic for today is about
atom, its structure and its sub- atomic
particles.
Now, cl ass let me intro duce to you our
objectiv es for t h is after noon.
• He discovered electron.
• He studied how alpha particles
interact with a gold foil.
• They disagreed with Aristotle
and said that matter could be
divided
Our topicufnotril it gets to the smallest part
today is acbaloleudt “atomos”
the a t o•m Hs e discovered the electron charge
ma’am. using his oil drop experiment.
• He is best known for introducing
the atomic theory into chemistry.
Everyb ody rea d .
At the duration of the lesson, learners are
expected to:
a. describe atom and its subatomic
particles;
b. locate the subatomic particles;
c. infer which subatomic particle
contributes to the atomic number
and mass of the atom;
d. give the importance of being a
part of a whole; and
e. create atomic model of a certain
atom/ element.
d. Purpose of the Lesson
This time class, I will group the class into
five groups. This will be your permanent
all throughout the session. Understood?

What you will be going to do is to read
poem entitled “Little Things” by Julia
Carney. Each group shall read stanza. Is
everyone ready?

Indicator
1.5.2
Alright! Let’s start with Group 1.
GUIDE QUESTIONS:
1. What makes the ocean mighty?
2. What are the little grains?
3. What makes our earth happy?
4. Why do little things make part of the
whole?
5. If you are given a chance to play a role
in the community, what role would you
choose to help our community a better
place?
Our lesson for today introduces a
discussion of purpose in the context of the
concept of parts in their relation to the
whole. We think of parts as serving a
purpose, or perhaps it would be more
accurate to say, as fulfilling a function
within a greater whole.
Just like the atom, it has fundamental parts
called the subatomic particles.
C. Presentation
(7 minutes)
Class, I will present to you the short video
about Atoms and Its Subatomic Particles.
D. Lesson Proper
(5 minutes)
Based on the video I presented, what is
an atom?
Indicator
1.4.2
Atom is the
smallest particle
and the building
blocks of matter
ma’am.
Very good, that is correct. All matters are
made up of atoms. Even us humans are
made up of atoms.
What makes up an atom?
It is made up of

its sub-atomic
particles called
electron, proton,
and neutron.
Very good. What are the charges of this
sub-atomic particles?
Does anyone from the class have any
questions or clarification?
Electron (e) has
negative charge,
proton (p) has a
positive charge,
and neutron (n) has
no electric charge.
None ma’am.
Let’s now proceed to the other part of our
lesson.

Now, class! We will have a group activity.
Form a circle with your group.
I will distribute a copy of Activity sheet,
Group Activity Rubric, and materials in
each group. (Attached after the lesson
plan)
Make sure to scan/ skim the activity. If you
have questions, feel free to ask. If none,
proceed and do your tasks.
Later, post your outputs here on the
board.
Choose/ assign representative/s from your
group who will explain your output in front
of the class.
You will be graded using the Rubrics
for Group Activity.

Inquiry-Based Questions
• Why do we need to study
atoms and elements?
• Why are they important even
though we cannot see them?
• Can you use the things that you
have learned in your everyday
living? How?
(Answers may vary. The teacher may also
lead the answer to practicing their critical
thinking. Investigating things like these
will develop their scientific mind. The
teacher may also lead the students to the
earlier poem – being a part of something
bigger)

1. It has a neutral charge.
2. It has a charge that would repel an electron.
3. It has a positive charge and found in the nucleus.
4. It moves randomly around the nucleus of an atom.
5. This is where the negatively-charged particle can be
found.
6. This subatomic particle determines the identity of the
atom.
7. This subatomic particle has a charge that attracts an
electron.
8. An atom with 3 protons & 2 electrons will have this
overall charge.
9. This is the region of the atom where almost all of the
atoms mass is
located.
10. Other than the answer to #3 it is another subatomic
particle found in the
nucleus.

GUIDE QUESTION:
Q1: What are the three (3) subatomic particles?
Q2: What do neutrons and protons have in common? How are they different?
B. Particles that are smaller than the atom are called subatomic particles. The three main subatomic particles that
form an atom are protons, neutrons, and electrons. The center of the atom is called the nucleus. Complete the
table below.

E. In the earlier discussion, you have encountered Bohr’s Planetary Model of an atom. Create your very own
atomic model using any materials that can be found in the classroom or the materials that you have with you
and your group. Take a picture of it and send it to your teacher so that your teacher can project it on the
monitor for your other classmates to see. Write a short explanation of your model on the space provided below.
