Teacher’s Activity Student’s Activity
A. Activating Prior
Knowledge 1. Routinary activities
Good morning class!
Good morning Ma’am!
How’s your day?
Its fine, Ma’am
That’s good to hear.
Before we start, may we all stand
and let’s acknowledge the presence
of the Lord.
(PRAYER)
Before taking your seat, please pick
up any pieces of paper or trash and
arrange your chair properly.
2. Checking of attendance
Is there any absent today?
None Ma’am.
Good, class secretary please take
note of your attendance. Thank you!
As we go on with our discussion
today, I want you all to remember
our classroom rules.
M – Maintain cleanliness
and order in the classroom.
E – Engage actively in class
discussions and activities.
L – Listen carefully when
someone is speaking
Is that clear to you class?
Yes Ma’am
3. Short Review
Last meeting, we have discussed
about main parts of the Earth, right?
Yes Ma’am
(Show to the students the diagram of
the sub-systems of the Earth)
What can you infer about the
diagram? Joey?
The diagram is all about the sub-
systems of the Earth, namely:
Hydrosphere
Lithosphere
Atmosphere
Precisely!
What is all about Hydrosphere and
Biosphere? Hydrosphere is all about the
Jovan? water here on Earth, from its
prefix “hydro” means water.
Biosphere is all about the
life here on Earth. Its prefix
“bio” means life.
Correct!
And how about Lithosphere and
Atmosphere?
Renalyn?
Lithosphere is all about the
solid land, rocks and
minerals, from its prefix
“litho” which means land.
Atmosphere is all about
envelope of gases
surrounding Earth, from its
prefix “atmo” means air.
Very well said!
Let’s give Joey, Jovan, and
Renalyn, a Ang Galing Clap!
It seems like you really understood
our previous lesson, and you’re now
ready for our next lesson.
B. Establishing
Purpose of the 1. Motivation

correct numbers (assigned to
each vowel) to find the
missing vowels and decode
the correct word
2. Each player will be given 10
seconds to guess.
3. If the student decode the
word correctly, he/she will
earn a point, if not, a new
player will be chosen.
Are the instruction clear, class?
Yes Ma’am
Alright, let’s begin.
Key Answer: 1.
1. ATMOSPHERE
2. TEMPERATURE
3. ALTITUDE

(The activity ends)
The activity that you performed has
something to do with our lesson for
today, which is all about “Layers of
the Atmosphere”.
Let’s explore the blanket of gases
that surrounds our planet.
Just sit back, relax and enjoy our
exploration.
C. Developing and
Deepening 1. Explicitation
Understanding (Let the learners read the reading
material “The Atmosphere of the
Earth”)
What is all about atmosphere?
The Atmosphere of the Earth
Atmosphere is the layer of gases
surrounding the Earth which is
essential to living things – it
provides carbon dioxide for plants
and oxygen for animals.
(Supplements information)
Atmosphere is the blanket
of gases surrounding Earth.
It makes life possible, as it
gives plants carbon dioxide
which they need in order for
them to grow and provides
animals, including us,
humans, with oxygen we
need, to breathe.
(Let the students continue read the
material)
The two (2) main gases that make up
the atmosphere are nitrogen and
oxygen. Argon and traces of other,
make up the rest. The total water
content in the atmosphere is about
0.25%, mostly made up of water
vapor.
Trivia Time!
Did you know that nitrogen makes
up nearly 78% of Earth's
atmosphere? Oxygen comprises
approximately 21%, while the
remaining 1% consists of trace gases
such as argon.
(Supplements information)
The water vapour content is
0.25%, which is important as
it helps form clouds, rains
and snow, which are part of
the water cycle.
Based from the material we read, let
me ask you questions.
What is the atmosphere?
Yes, Daniella?
The atmosphere is the layer of gases
surrounding the Earth.
That’s the idea, Daniella!
What is in the atmosphere?
You are recognized, Jaypee.
The atmosphere contains various
gases, including nitrogen, oxygen,
and trace amounts of gases such as
carbon dioxide and argon. It also
contains 0.25% of water vapor.
Perfectly said, Jaypee!
(Shows to the students diagram of
the different layers of the
atmosphere)
(Identify the different layers of the
atmosphere)
We are now at the first layer of the
atmosphere, can anyone guess its
name and describe it?
Lloyd? Troposphere is the first layer
of the atmosphere and the
layer nearest the Earth’s
surface. From its prefix
“TROPO-” means change. It
is where hot air balloons and
airplanes can fly in this layer.
Exactly!
Troposphere, the layer
where all weather
conditions occur. Among all
layers, this is the layer
where we can breathe freely.
Temperature decreases as
altitude increases.
How about the next layer above the
troposphere? Can you tell where we
are, Juliana?
The second layer above the
troposphere is stratosphere.
“STRATO” means layer. Jet
planes can fly from this area.
Excellent!
Stratosphere the only layer
where you’ll find the very
important ozone layer which
protect us from ultraviolet
radiation (UV) from the sun.
Jet plane fly in this layer (in
the lower part) partly
because it is a less-turbulent
area.
The temperature increases
as altitude increases.
What about the third layer? Can
you guess what is it? Allen?
The third layer of the
atmosphere is the
Mesosphere. Its prefix is
“MESO-” means middle.
Meteors can pass in this layer.
Great!
In mesosphere, most
meteors burn up due to its
thin air and the friction it
generates.
The temperature decreases
with the increase in altitude.
Moving on to our fourth layer,
would you mind to tell the name of
our fourth layer of the atmosphere
and describe what is all about?
Kath.
Thermosphere is the fourth
layer where ionosphere is
located. From its prefix
“THERMO-” which means
heat. In this layer, Northern
Good! Lights appears.
The thermosphere is the
hottest layer because it
absorbs high-energy X-rays
and UV radiation from the
sun.
Contains a layer of charged
particles called the
ionosphere, which makes
communication by radio
waves possible and home to
the aurora borealis.
Now class, we are at the upper limit
of the atmosphere.
Who among you has an idea on
what it is?
Yes, Dan? Exosphere is the fifth layer,
found at the outermost
regions of Earth’s
atmosphere. Its prefix “EXO-
” means outer. Satellite can be
found in this layer.
Excellent!
Exosphere the fifth layer,
the final frontier of the
Earth’s gaseous envelope.
More space like than
thermosphere with very thin
air.
2. Application
At this point, we will going to have
a group activity, titled “Label Me”.
Everyone read the instruction.
Activity: Label Me
Instruction:
Label the layers of the
atmosphere with their
corresponding events and
features using a diagram.
The students will only be
given 3 minutes to finish the
activity.
After the given time, two (2)
representatives of each group
will present their output in
front within 2 minutes.
Do you understand the instructions,
class?
Yes Ma’am
Okay, you may start.
(The activity starts)
(The activity ends)
(Presentation of output)
I’m glad that you all understand the
key concepts of our lesson today.
Let’s give everyone a
Congratulations Clap.
D. Making Basically there are 5 layers of the
Generalization Earth’s atmosphere. What are
those?
1. Troposphere
2. Stratosphere
3. Mesosphere
4. Thermosphere
5. Exosphere
That’s right!
Each layer has distinct
characteristics and functions,
ranging from supporting life and
weather in the troposphere to
serving as the transition to space in
the exosphere.
In order for you to easily remember
the 5 layers of the Earth’s
atmosphere, just always remember
this MNEMONICS.
The Superhero Magically
Travels Everywhere
Since you already understood our
topic, I have questions for you
class.
What is the importance of
atmosphere for us human being?
Go ahead, Mj.
The atmosphere is important for life
here on Earth because it provides
carbon dioxide for plants and oxygen
for animals and us, humans.
Perfect!
In the troposphere, we humans can
breathe freely also in this layer,
pollution mostly stays. What
happens if too much pollution build
up in this layer?
Share with us your thoughts, Leira.
It can cause health problems Ma’am,
like asthma.
Well said, Leira.
Much pollution can lead to
respiratory and health diseases just
like asthma, lung infections and risk
of heart attacks. As it builds up in the
troposphere layer, it also traps heat
leading to global warming.
Class, do you know how this affects
other layers of the atmosphere?
Go ahead, Bea.
The ozone layer which is found in the
stratosphere, gets damaged which
can be harmful for us, humans.
Exactly, Bea!
Some chemicals like
Chlorofluorocarbons (CFC’s), break
down in the ozone layer allowing
harmful UV rays to reach us.
Here’s a challenge: Can you think of
ways we can help reduce pollution
and slow down global warming?
Yes, Rico?
Ma’am planting and nurturing more
trees.
Good!
Other idea, Rick.
Using less plastic, recycling
materials and segregating waste.
Nice idea!
It feels so overwhelming that you all
made it right and well. Give
yourselves a Jollibee Clap!
