INTRODUCTION
A. Prayer
(The teacher calls the Prayer Leader)
Good morning, Class!
Good morning, Teacher.
How are you today class?
We are fine and good Teacher.
Wow. That’s good to hear. I’m glad you are all doing
fine.
Now, let us check the attendance first.
Who is the secretary of the class? May I know who
are the absentees for today?
None teacher.
B. Setting of Standard
Before we proceed to our proper discussion there are
things to be consider in order to have an organize
class. What are they?
Listen to the Teacher attentively.
Raise your right hand when you want to answer.
Participate in the activity
Respect one another.
Can I expect all of these to you class?
Yes teacher.
C. Review
What was our past discussion?
Our last topic is all about sound energy. Sound
is a form of energy. There are different kinds of
sound produced by so many things in so many
ways. Sounds can be produced by animals,
vehicles, objects, musical instruments, nature
and by people.
How is sound produce?
Sound is made by vibrations. When any objects
vibrate, it produces movements in the air
particles. These particles bump into the particles
close to them to vibrate and bump into more air
particles. If your ear is within range of the
vibrations, you will hear the sound.
Very good! Are there any questions that you would
like to ask? Or any clarifications before we proceed to
our new topic.
None Teacher.
C. Motivation
Before I formally start our discussion for today, I want
you to look at this video first and try to observe.
https://www.youtube.com/watch?v=TBN3JeTD5V8
Processing Questions
1. What have you notice with the video?
2. The astronauts photographed the earth from space
and that’s why they come up with a nickname, what is
it?
3. How many percent of the earth does water occupy?
4. Water can be found in all three states of matter. Can
you give me an example?
Very Good! Let us give 5 Claps for everyone.
F. Presentation
Now I want you to look at the pictures in the TV
screen and observe.
It is all about the earth’s water teacher.
The Blue Marble.
71% of the earth’s surface is covered with water.
The three states of matter are the solid, liquid
gas. Example of solid is the ice, the liquid is the
rain and for the gas is the clouds.
*5 Claps*
Processing Questions
1. What have you notice with the pictures?
2. Are all pictures do have water in it?
3. Do you see these examples in your surroundings?
Or have you been to a place like these before?
There is a river, a sea, a lake, a fall, a pond, a
dam, an underground water and a rain teacher.
Yes teacher.
Yes teacher. We went to the sea last Sunday
with my family.
Excellent Class! Let’s give ourselves a Good Job
Clap!
*Good Job Clap*
Base on the picture, what do you think is our topic for
today?
Is it about the water teacher?
Correct! Our topic is all about the earth’s water.
INTERACTION
G. Abstraction/lesson proper
Let’s learn more about the earth’s water.
Can you imagine a life without water?
Very good! Water is important to all living things,
especially to us, human. Do you know that water
makes up 83% of our blood. 70% of our brain, and
90% of our lungs. Overall, our bodies are 70% water.
Earth is called “water planet”. Viewed from space, the
most striking feature of our planet is the water. That is
why the astronaut named planet earth as The Blue
Marble. The ocean holds 97% of the earth’s water.
Water is practically everywhere on earth. Without
water, earth would look like the Moon.
All living things need water to live. People can live
several weeks without food, but only a few days

bath. When I’m thirsty and when I water the
plants in our house.
without water so we should drink six to eight glasses
of water each day.
Now, we will proceed on the sources of water. A
while ago I have presented some pictures, right? those
are what we called, forms or bodies of water.
Let us start first with the ocean and sea. Ocean is a
vast body of salt water that covers almost ¾ of the
earth surface. Example the Pacific, Atlantic, Indian
and Artic Ocean. Sea on the other hand, is a body of
salt water that surrounded by land on all or most sides,
and is part of one of the oceans. Example is the
Boracay.
Can you give me another example of a sea?
Orange Farm teacher in Lawigan.
River is fresh water that flows from mountains and
empties into a sea, lake or another river. People love
to swim in the rivers. They also wash their clothes,
catch fish and get their drinking water. Example is the
Enchanted River.
Waterfall is a place where water travels rapidly and
drops to a lower elevation as it goes and flows over a
steep cliff or area of land. Example is the Maria
Cristina Falls in Iligan.
Can you give me another example of a waterfall?
Tinuy-an Teacher.
Lake is a body of water surrounded by land. Most
lakes have fresh water. Example is the Taal Lake.
Pond is a body of standing water, either natural or
man-made, that is usually smaller than a lake.
Who wants to eat bangus and tilapia?
Alright, bangus and tilapia usually grown in ponds.
Me Teacher.
Dam is a large wall or barrier that stops the flow of
water, forming a reservoir or a lake. The purpose of
the dam is usually to stop or slow down the movement
of the water. This is usually done to retain the water
in one area so that it can be used to irrigate rice field,
and supply the water needs of a community.
Underground water, when rain falls to the ground, the
water does not stop moving. Some flows along the
land surface to stream or lakes, some is used by plants.
when underground water comes out through cracks of
rocks, the result is spring. Have you visited any hot
spring or cold spring?
Many households in rural areas rely on artesian wells
to meet their daily needs for fresh water. Other makes
a water well.
Rain is one important source of water. Is the product
of water from the earth that has evaporated into the
earth’s atmosphere and is turned into rain. During that
process, the water becomes fresh water and cultivated

in many places throughout the world to be used as
suitable supply of drinking water and water to feed
crops.
Do you have any questions about the forms of water?
Okay so now we will proceed on why water
conservation is important.
None Teacher.
Since 71% of the earth is covered in water, some
people can't help but wonder. Why should we
conserve?
.
Ninety-seven percent of all water on the earth is salt
water, which is not suitable for drinking.
Only 3% of water on Earth is fresh water, and only
0.5% is available for drinking. The other 2.5% of fresh
water is locked in ice caps, glaciers, the atmosphere,
soil, or under the earth's surface, or is too polluted for
consumption.
With growing population rates and such a small
percentage of all the water on Earth fit for
consumption, it only makes sense that we must
preserve and conserve this precious resource.
Water conservation means using our limited water
supply wisely and caring for it properly. Since each of
us depends on water to sustain life, it is our
responsibility to learn more about water conservation
and how we can help keep our sources pure and safe
for generations to come.
Is it clear class? Any questions or clarifications?
Okay so now we will proceed to our short group
activity.
Materials:
Cartolina
Marker
Crayons
Ruler
Pencil
Eraser
Direction: Create a slogan persuading people to
conserve water.
Rubrics for Slogan Making
None Teacher.
Let’s have another game. This game is called "Guess
Me”. I will be presenting pictures and you will have to
guess what type of bodies of water I am showing to
you.
1. Dam
2. Waterfall
3. River
4. Ocean
5. Lake
6. Pond
7. Underground Water
8. Rain
Did you enjoy our game class?
I am Glad you enjoy our game. Let’s give clap A for
everyone.
Yes Teacher.
*Clap A*
H. Valuing
What have you learned today?
I learned that ocean holds 97% of the earth’s
water. Water is practically everywhere on earth
and that all living things need water to survive.
Why it is important to conserve water?
It is important that we conserve water teacher
since all living things needs water to live and
only 3% of water on Earth is fresh water, and
only 0.5% is available for drinking. With
growing population rates and such a small
percentage of all the water on Earth fit for
consumption, it only makes sense that we must
preserve and conserve this precious resource.
As a student, what can you do to conserve water?
I can help conserving water by simply turning
off the water while I’m brushing my teeth. If
washing the dishes by hand, don't leave the
water running for rinsing, don’t run the hose
while washing the car and watering the plants.
Awesome! Thank you everyone for sharing your
thoughts and experiences. And I hope you learn
something today.
