Review
I have here an envelope filled with pictures. All of
you must pick 1 picture. After which you are going
to pass it to the person next to you.
Now that all of you have a picture at hand kindly
look for your group mates who has the same
picture as you do. For the rain group please stay
here. All satellites please seat here. All meteors
stay here. Earth group be seated there and Sun
group please occupy that table.
Today we are going to play “Spot the Difference
Game” Do you know how this works? I’ll be
showing you two pictures which are almost
similar. All you need to do is to spot the difference
by clicking the picture. In order to be recognized,
your group must stand up, wave the pictures while
doing the chicken dance just like this (teacher
demonstrates the chicken dance). Once
Heavenly father…..Amen.

recognized, your representative must come in
front and click the picture which is worth 5 points.
Each picture corresponds to a given question,
answer the question correctly and you will be
rewarded with an additional 5 points. If you fail to
answer, the rest of the class has the chance to
steal or answer.
Am I understood? Any clarifications? If none, let’s
start the game!
B. NEW LESSON
Motivation
This morning we are going to play “4 pics 1 word”.
I will be flashing 4 pictures and below these
pictures are scrambled letters which you will
arrange in order to form 1 word that represents
the pictures. You will be given a slate board to
write your answer. The first group to raise the
correct answer earns 5 points. The group with the
most number of points wins the game. Please
remember, that any unnecessary noise is a
demerit to your points. Am I clear? Are you
ready?
Presentation
How do we look like if we don’t have skin? Have
you ever imagined yourself skinless?
What do you think is the role of your skin?
Now try to imagine the earth without an
atmosphere. What do you think will happen to the
planet earth?
Very good! Today we are going to explore our
atmosphere; we’ll get to know the 5 layers of the
atmosphere and its characteristics. Are you ready
to explore and travel?
So fasten your seatbelt, open your mind, eyes
and ears to capture and focus, to learn and to
enjoy the trip.

Gas Composition of the
Atmosphere
Earth – News Reporting/News casting
Meteor – Talk show
Rain – Role playing
You will be given 5-7 minutes and 3-5 minutes for
your presentation, after which, you will present the
group’s output. Here’s the rubric on how I am
going to grade your presentation (please refer to
appendix A for the rubric)
(The teacher facilitates the group activity.)
Group 1 – SUN GROUP.
Instruction: By using the pie graph, answer the guide questions by creating a lively jingle.
Discuss the gas composition of the earth’s atmosphere by creating a lively JINGLE.
Guide Questions:
1. How much of the gases are present in our atmosphere?
2. Why do you think these gases are important to us?
3. What are the 2 most abundant gases in the atmosphere?
Read the Selection
Gas Composition of the Atmosphere
A. Nitrogen - 78% - Dilutes oxygen and prevents rapid burning at the earth's surface. Living
things need it to make proteins. Nitrogen cannot be used directly from the air. The
Nitrogen Cycle is nature's way of supplying the needed nitrogen for living things.
B. Oxygen - 21% - Used by all living things. Essential for respiration. It is necessary for
combustion or burning.
C. Argon - 0.9% - Used in light bulbs.
D. Carbon Dioxide - 0.03% - Plants use it to make oxygen. Acts as a blanket and prevents
the escape of heat into outer space. Scientists are afraid that the burning of fossil fuels
such as coal and oil are adding more carbon dioxide to the atmosphere.
E. Water Vapor - 0.0 to 4.0% - Essential for life processes. Also prevents heat loss from the
earth.
F. Trace gases - gases found only in very small amounts. They include neon, helium,
krypton, and xenon.
Gases Amount (%)
Nitrogen 78
Oxygen 21
Water Vapor 4
Argon 0.9
Trace Gases 0.3
Carbon Dioxide 0.03

5. 4
Group 2 – SATELLITE GROUP.
Instruction: Label the 5 layers of the atmosphere and identify the things commonly found in
each layer. Distinguish its distance (km) from the earth’s surface. Present it to the class through
a GAME SHOW.
Guide Questions:
1. What are the 5 layers of the atmosphere and how do they differ from each other?
2. How far are the layers of the layers of the atmosphere from the surface?
Read the selection.
ATMOSPHERIC LAYERS
1. The troposphere (0-16 km) is the first layer above the surface and contains half of the
Earth's atmosphere. Weather occurs in this layer. Air in the troposphere is constantly
moving as a result aircrafts flying may have a bumpy ride (turbulence). Lowest in the
north and south poles at 5 km and highest near the equator at 16 km above the earth’s
surface.
2. Many jet aircrafts fly in the stratosphere because it is very stable. Also, the ozone layer
absorbs harmful rays from the Sun. 16 to 50 kilometers above the earth's surface.
3. Meteors or rock fragments burn up in the mesosphere. Extends 50 to 80 kilometers
above the earth's surface.
4. The thermosphere is a layer with auroras. It is also where the space shuttle orbits.
Different regions of the ionosphere (extension of thermosphere) make long distance
radio communication possible by reflecting the radio waves back to Earth. Starts at
about 80 km high and continues to 640 km.
5. The exosphere is the outermost layer of the Earth's atmosphere. The exosphere goes
from about 640 km high to about 1,280 km. Satellites are stationed here.
Ionosphere

6. 5
Group 3 – EARTH GROUP.
Instruction: Graph the estimated temperatures of each layers of the atmosphere and discuss
the temperature variations. Present it to the class through NEWS REPORTING/NEWS
CASTING.
Guide Questions:
1. What are the estimated temperatures of each layer?
2. What is the relationship between altitude and temperature in each layers?
3. On what layers of the atmosphere shows that the temperature increases as the altitude
increase?

Temperature and the Atmospheric Layers
The temperature ofthe Earth’s atmosphere varies with altitude;the relationship between temperature and altitude
varies between the different atmospheric layers:
 Troposphere – 0 to 16 km, temperature decreasing with height.
 Stratosphere – 16 to 50 km,temperature increasing with height.
 Mesosphere – 50 to 80 km, temperature decreasing with height.
 Thermosphere – 80 to 640 km, temperature increasing with height.
 Exosphere – 640 +, temperature is increasing with height.
The air at the surface up to around 16 kilometers is called the troposphere. The reason itis warmer at the surface is
simple.The air is warmed by heat given off by the Earth! The farther away from the surface the air moves,the less
heat there is to absorb.
From 16 to 20 kilometers the atmosphere is stable.From 20 to about50 kilometers in this region the air actually
warms with height!Ozone is concentrated in this part of the atmosphere and it absorbs ultraviolet lightfrom the Sun.
More lightis absorbed athigher altitudes compared to the lower stratosphere, so the temperature increases.
At about50 km,the mesosphere begins.In the mesosphere, the temperature decreases with heightagain,because
there is very little ozone to warm up the air.
Thermosphere which is the section ofthe atmosphere higher than 80 km. In this region,the temperature increases
again!This time,it is molecular oxygen (O2) that causes the temperature increase.The oxygen absorbs lightfrom the
Sun, and since there is very little air in the thermosphere, justa little absorption can go a long way!
The exosphere is almosta vacuum. The "air" is very, very thin there. When air is thin, it doesn'ttransfer much heatto
objects in the air, even if the air is very, very hot.

8. 7
What are the main components of our
atmosphere?
What is the importance of nitrogen?
Our atmosphere is divided into how many layers?
And what are these layers?
I’ll give you mnemonics about the layers of the
atmosphere to better remember it.
Troubled = Troposphere
Super = Stratosphere
Man = Mesosphere
Tricked = Thermosphere
Ellen = Exosphere
What are the common scenes we usually
observed on each layers?
What do you think is the basis for the division of
our atmosphere?
In what layers of the atmosphere does the
temperature increase with height?
In the troposphere, why do you think temperature
decrease as altitude increases?
Why do you think the temperature in the
stratosphere increases with height?
Nitrogen and oxygen are the main components
of our atmosphere. Together they comprise
99% of our atmosphere.
Nitrogen is used for bulbs, explosives, tyres,
helps in processing fertilizers, acts as
neutralizer, and helps in body buildings
proteins.
We have 5 main layers namely from top to
bottom: Exosphere, Thermosphere,
Mesosphere, Stratosphere and Troposphere.
Troposphere is where the weather forms;
commercial airplanes also fly on this layer. The
air is very unstable on this layer that’s why we
sometimes experience a bumpy ride which we
call turbulence. The highest peak in the world
which is the Mt. Everest also seats in this layer.
Stratosphere is where a spy jet flies because
the air is very stable. Ozone layer is also found
here.
Mesosphere is where meteors and other rock
fragments burn up.
Thermosphere is where auroras are found.
Sun's energy is so strong at this level, that it
breaks apart molecules. So there ends up
being electrons floating around and molecules
which have lost or gained electrons that is why
we have radio signals because of this layer.
Exosphere, the outermost layer and extends
through space. It is where the satellites are
stationed.
Due to temperature variations ma’am!
In the Stratosphere, Thermosphere and
Exosphere.
The air is warmed by heat given off by the
Earth! The farther away from the surface the air
moves, the less heat there is to absorb.
Because of increasing amounts of ozone which
absorbs harmful UV lights.

9. 8
In the mesosphere, temperature decreases as
height increases, what do you think causes this
temperature variation?
Temperature increases with altitude in the
thermosphere. Give a possible explanation.
What are the relationship of altitude and
temperature between each layer?
How does our atmosphere help and protect us?
Valuing
Now, imagine our planet without the atmosphere,
what do you think will happen?
How can we be able to survive?
Now that we’ve learn the importance of our
atmosphere as students, how can you help
protect our atmosphere?
Well said.
(Video clip on global warming)
There is very little ozone to warm up the air.
The few molecules that are present in the
thermosphere receive extraordinary amounts of
energy from the Sun, causing the layer to warm
to such high temperatures

Exosphere Directly proportional
Atmosphere helps us in many ways:
1. Breathing comes naturally. We need oxygen to
keep our bodies working.
2. A radiation shield.
3.
4. Security Blanket. The atmosphere also keeps
us warm.
5.
6. Weathering the storm. Closely related to
temperature regulation, the atmosphere also
gives us weather.
7.
8. Look out below! Another really important thing
that the atmosphere does is to protect us from
objects coming toward the earth from outer
space.
9.
Plant life. The atmosphere is also very
important for plants because it contains a small
amount of carbon dioxide. Plants use the
carbon dioxide (CO2) along with sunshine to
carry out a process called photosynthesis.
Let’s Talk. One more thing the atmosphere
does is it allows us to talk to each other. If you
were talking to your friend and there were no
air between the two of you, your friend would
not be able to hear a thing you said.
Life might not be possible on earth because
temperature will not be regulated.
We must conserve energy and lessen the use
of harmful chemicals. We must plant more
trees and be a good shepherd to our natural
resources.

10. 9
Generalization
It is cooler in Baguio that in Manila. Baguio is at a
higher altitude than Manila. Shouldn’t it be
warmer in Baguio since it is a lot closer to the
sun?
The troposphere is warmed primarily by
infrared radiation emitted by Earth’s surface.
Increasing altitude also increases the distance
from the heat source leading to a decrease in
temperature.
Quiz Bowl - Directions: Multiple choice. Before a question is read, each group must raise the
