PROCEDURE
Teacher’s Activity
A. Preparatory Activities
a. Prayer
Let us begin our lesson today with a prayer.
Alex, please lead the prayer.
IV.
Student’s Activity
“Dear God……Amen.”
b. Greetings
Bright morning class!
“Brighter morning teacher!
It’s nice to see you this morning.”
It’s nice to see you too!
Before you take your seats kindly pick up the
trashes you can see inside the classroom and
put
it in the trash bins. Arrange your chairs
(The students picked up some pieces of paper and
before seating. Alright, please settle down.
arranged their chairs.)
c. Checking of Attendance
Let us check your attendance first. Say
present if your name is called.
“Present!”
Alingasa, Alex
(and so on)
d. Setting of classroom rules.
So, before we proceed to our lesson today,
let us first be reminded to our classroom
rules.
(Everybody will read)
B. Elicit
Before we proceed to our lesson, let’s have
first a quick identification. I will show some
pictures here and you will identify whether
it’s matter or not.
(The students will read.)
“Matter”
This Photo
Leaf
“Matter”
Smoke
“Matter”
Bottle of water
“Matter”
Air inside the ballon
“Not matter”
Shadow
“Not matter”
Sunlight
Very good!
It is good to know that you are now able to
identify which is matter and which is not.
Now, matter exists in nature in different
forms. Some substances are rigid and have a
fixed shape like wood and stone; some
substances can flow and take the shape of
their container like water, while there are
forms of matter that do not have definite
shape or sizes such as air.
C. Engage
Now, to further expand your knowledge
about matter, let’s have a group activity.
I will divide this class into five groups. The
first row will be the group 1, and the last row
will be the group 5.
Alright, now go to your respective groups,
silently.
Now, listen carefully. If I say “compress”,
you will move forward to each other as if
you are having a group hug. If I say “near”,
you are going to
move a little bit away from each other and if
I will say “far”, you are going to move away
from each other as far as you can.
The group who followed
everything I said will gain 10 points.
Are you ready?
Yes, sir.
The game begins
(The class participated)
Alright, let us give five claps to every one of
us for participating in the activity.
*clap *cap *clap *clap *clap
Now, please settle down as you
sit with your groupmates.
D. Explore
Activity Proper
Now, in each group, I want you to prepare
two different kinds of materials that you will
see inside this classroom.
It can be water, chalk, anything that you will
see inside your classroom.
After that, you will share to the class about
your observation and the differences of the
two materials that you have found.
(The students will settle down)
I will give you 2 minutes to look for the
materials and 3 minutes to brainstorm with
your groupmates about its differences and
your observations.
Do you understand?
“Yes, sir.”
(Every group will participate)
E. Explain
Okay time is up! Let us hear your
observations. Let us first hear the
observations of group 5 followed by group 4
down to group 1.
(The students will present their works.)
As you can see, all of the materials you have
shown in the class are all considered as
matter.
Why? Why do we consider those
things as matter? Can someone in the class
tell me what is matter? Yes, Lobaton.
“Matter is anything that occupies space, has mass
and take up volume.”
Yes! Very good!
Matter is anything that occupies space and
mass and take up volume. The leaves,
smoke, water, and air inside the ballon are
just some examples of matter. Shadow is not
an example of a matter since shadow does
not have mass although it occupies a space.
And these things that you have presented are
all considered as matter. Even the things that
you cannot see, those are also
considered as matter.
Have you ever wondered what makes up
matter?
“An atom sir?”
Yes, that is correct.
Why do you think some are hard, some are
not?
F. Elaborate
Now to further understand more about
matter, be with me today as we talk about
The Particle Nature of Matter.
At the end of this lesson, you
are all expected to,
Please read.
(Silence)
“At the end of the lesson, the students are expected
to:
a) Explain the properties of solids, liquids,
and gases based on the particle nature of
matter (S8MT-IIIa-b-8);
b) classify materials as solids, liquids, and
gases; and
c) explain the four basic aspects of the
particle nature of matter
d) Appreciate the real-life application of
physical changes on the phases of matter
through the water cycle.”
Matter is made of tiny particles. Just like
what you have mentioned earlier, these
particles are called atoms.
Now, why do you think some matters are
hard like this table and some are liquid like
this water?
This is because matter has three states. And
that the particles are arranged
depending on their states. Let us further
unlock that question as you take a look at
this picture.
Particles in solid
This is the arrangement of particles in solid.
What can you say about the particles in a
solid?
“The particles are very close to each other.”
Very good!
Indeed, the particles in the solid are tightly
packed together.
Now, since they are tightly packed together,
can you say that the particles can move?
Just like what you did earlier when I said
compress, all of you were so close to each
other right? That is an example of how
particles are arranged in a solid matter.
“No sir, the particles cannot move because there is
no space for them to move.”
How about this one?
Particles in liquid
What can you say about the particles in a
liquid matter?
“The particles are slightly close to each other, sir.”
Yes! That is correct.
Now, do you think, the particles
can move?
“Yes, sir.”
Just like what you did in our activity earlier,
you were slightly close to one another but
not too far. Just enough space for you to
move.
How about this picture?
Particles in gas
What can you say about the particles in a gas
matter?
Yes, but do you think the particles can
move?
Why do you think so? Yes, Gesim.
That’s right!
“The particles are so far from each other sir”
“Yes, sir.”
“Since the particles are not tightly packed together
and the particles are so far from each other, the
particles can move freely.”
Just like what you did earlier in our activity
when I said “far”. You move away from each
other and create a great space for everyone to
move to.
Solid
It has a definite shape and volume because
its particles are closely packed together in a
fixed position. These particles vibrate and
are held together by strong attractive forces.
It is difficult to compress the particles.
Here are some examples.
Chair
metal
books
Liquid
It has a definite volume and takes the shape
of the container. Liquid flows easily because
its particles have enough space and have less
attractive force. The spaces in the particles
allow particles to be compressed a little bit
Here are some examples.
water
oil
coffee
Gas
It takes the volume and shape of the
container. Gas particles are far from each
other that is why they have the weak
attractive force and can flow easily. They
occupy the entire space available. The large
spaces in between particles allows particles
to be compressed easily.
Here are some examples.
Air inside the
Ballon
smoke from
motorcycle
air in the wind
Now, why do you think some are hard and
some are not?
This is because of the arrangement of the
particles in matter. Some have compact
particles that is why it is hard to be
compressed. Some are free to move easily
and are held together by less attractive
forces. And some are far from each other and
they occupy the
entire space available.
These properties of the states of matter can
be best explained using the particle nature of
matter which consists of the four basic
aspects.
 Matter is made up of tiny particles.
 The particles of matter are moving
all the time.
 These particles have spaces between
them.
 The particles of matter attract each
other.
The model states that what solids, liquids,
and gases are, explains the differences in
their behavior.
But do you know class that you can see all
these changes or states of matter in water?
Water exist in three states such as ice as solid
state, water as liquid state, and water vapor
as gas state.
Now, imagine if there are no three states of
water. What would be its result?
“That would cause a significant effect especially to
us sir because if there are no three states of matter
that exist in water, that means water does not
exist—and that signifies that no such living thing
would exist since water is the source of life.
Without water no such thing would exist. In that sir,
water really plays a crucial role in maintaining life
especially in our day-to-day lives”
That’s right Alex.
It is important to know that these three states
of matter happen in our daily lives. And that
we can apply that to our lives. For example,
if I want to cook rice, I need water. If I want
to dry my clothes, all I need to do is to hang
it under the heat of the sun. and if I need to
make an iced coffee, of course I need ice.
That is the significance of the three states of
matter present in water in our day-to-day
bases.
