lesson
(Elicit)
Since everyone did well with our past lesson. I
hope you will all be well with our next new lesson
this week.
But before we dive on to our proper discussion,
let’s play a game.
This game called “Give my direction”
The mechanics of this game is I will flash the
picture all you need to do is to determine if the
direction of the picture is to the North, south, west
or east.
Do you understand class?
Yes Ma’am.

4. Very good!

is this four pics one word. What word comes first
to your mind?
Yes maam!
The words are Prevailing winds

5. Very good! It’s Prevailing winds
Alright in order for you to know what prevailing
wind is let us now proceed to our lesson for this
morning, but before that I want you to read the
objectives of our lesson

D.Discussing new
concepts and
practicing new
skills #1 (Engage)
Thank you!
So first let us define what is prevailing winds,
I am going to show you a picture and I want
you to analyze and describe what prevailing
wind is.
Anyone who wants to share their thoughts
and ideas?

Okay thank you! Let’s see if you have
defined it correctly
(Students will read the objectives)
Learning Objectives:
At the end of the lesson, students should be able to:
1.describe the formation of prevailing
winds
2.identify and explain circulation cells
3. cite at least three importance of
prevailing winds in human activities
Answer may vary.

6. Prevailing winds are wind directions
over a particular location on Earth
due to uneven heating from the sun
and the rotation of earth on its axis.
The equator receives most direct
sunlight and greatest concentration of
heat resulting to a warm temperature
while at the poles, there is a lower
concentration of heat resulting to a
cold temperature.
The warm air in the equator expands,
become less dense, and rises. As the
air rises, it cools, decreases its
pressure, and loses water vapor
forming a low-pressure area at the
equator. The rising air at the equator
does not flow directly to the poles
because the Earth rotates on its axis
causing an air build up at 30˚ north or
south latitudes.
E.Discussing new
concepts and
practicing new
skills #2 (Explore)
To know more about Prevailing winds, I want you
to perform this activity
This will be performed by group.
I will divide you into five groups based on your
cleaner’s schedule.
_______, please read the objectives?
Please write your answer in the blank space found
in your answer sheet. And also please write your
group members at back of your activity sheet.

Objectives of this activity:
Objectives:
Identify and label Earth's major prevailing
wind systems.
Understand the role of Hadley, Ferrel, and
Polar cells in generating these wind patterns.
Analyze how prevailing winds influence
weather patterns and climate at different
latitudes.

7. You will be given 5 mins to finish your activity.
You may now start.
F.Developing
mastery
(Leads to
formative
assessment )
(Explain)
Okay class, times up.
Class, let’s check and discuss your answers.
Class, for A and F. What is your answer?
Alright! Very Good! Based on the illustration on
the activity sheet, where can we find the Polar
Cell?
Very Good! Based on the colors of lines that
represent the air temperature, What type of air
does the Polar Cell circulate? Is it warm air or
cold air?
Alright! Very good! The polar cell is a circulation
pattern in the Earth's atmosphere that moves cold
air from the lower latitudes to the poles and back
again. It's the smallest and weakest of the three
main circulation cells in the atmosphere. 
Next class, let’s move on to B and E.
The answer is Polar Cell Ma’am.
Polar Cell is formed between 60˚ and 90˚ latitude.
The air cools over the poles and sinks to the Earth’s surface.
These surface winds in the polar cell are called easterlies.
Ferrel Cell Ma’am
.

8. What is your answer?
Correct! The answer is Ferrel Cell
Class, how do you define Ferrel Cell?
Very good! A Ferrel cell is a mid-latitude
atmospheric circulation pattern in the Earth's
atmosphere, located between the Hadley cell (near
the equator) and the Polar cell (near the poles),
where air moves towards the poles at the surface
and then back towards the equator at higher
altitudes, creating prevailing westerly winds in the
mid-latitudes; named after American
meteorologist William Ferrel who studied its
dynamics related to the Earth's rotation. 
Class, next let’s move on to C and D.
What is your answer?
How do you define Hadley Cell?
Exactly! Hadley Cells are the low-latitude
overturning circulations that have air rising at the
equator and air sinking at roughly 30° latitude.
They are responsible for the trade winds in the
Tropics and control low-latitude weather patterns. 
Ferrel cell is created when the air between 30˚ and 60˚
latitudes meets the cold air from the poles. These winds are
called westerlies that characterize weather patterns in the
temperate zones.
Hadley Cell Ma’am.
is the air moving toward the equator. It is responsible for the
dry climate at 30˚ latitudes or the tropical and subtropical
regions and drives circulation of air north and south of the
equator.
G.Finding practical
applications of
concepts and skills
Alright! Now that you have an idea what are
prevailing winds, let me ask you this question,
How can we apply our knowledge of prevailing

9. in daily living
(Elaborate)
winds to our daily living?
Class, studying prevailing winds has many
important in human activity.
For example, in Agriculture - Prevailing winds
help regulate temperature and distribute moisture,
influencing crop growth and agricultural practices.
For instance, they can bring rain to farming
regions or dry winds that affect soil moisture.
Some more idea class?
Okay very good!
Please note this some important of prevailing
winds in human activities.
Do you have any question class?
Navigation and Transportation - Historically, prevailing
winds were essential for maritime navigation. Sailors relied
on trade winds for efficient ocean travel, and today, wind
patterns still influence flight paths for aircraft to save time
and fuel.
Ma’am! Renewable Energy - Prevailing winds provide a
consistent source of wind energy, making them crucial for
the placement and efficiency of wind farms to generate
electricity.
