I.
Objective:
At the end of the lesson, student will be able to:
Identify the processes involved in the water cycle.
Discuss the role of the sun in the water cycle.
Suggest ways to help conserve water and prevent water pollution.
II. Subject Matter:
Title: Water Cycle
Reference: Internet
Materials: Pictures
Cartolina
Colored Paper
III. Methodologies:
A. Preparation
B. Motivation (Short Video Clip)
C. Discussion
D. Presentation / Games
IV. Teacher’s activity:
Teacher Student
PREPARATION:
Good Morning Class Good Morning Ma’am
Before we start our day let Claret leading the prayer
claret lead us in prayer this
morning
You may be sited and will The students will sit
check your attendance
How’s your day class We’re good Ma’am
MOTIVATION:
Know what class Teacher Some student will say “why
Jasmine is sad today Ma’am? Why are you sad”
Because a glass of water spill One student will say “Ma’am
on my t-shirt (Pull the wet you don’t need that
shirt out of my bag and show anymore, throw it away now
to them). Ma’am”
Do I need to throw it away? Most of the students say
“Yes Ma’am”
(Give the students time to Claret - Ma’am wait until it
object, hopefully someone dry so that you can use it
will suggest that the shirt will again
dry)
How or what will I do to We don’t know Ma’am
make it dry?
When you hear the word dry, The students listen carefully
there is no water or moisture
on it
Where does the water goes We don’t know Ma’am
when something is drying?
Today, you will be learning Ok Ma’am
where water goes and the
process is what we call the
water cycle
I will let you watch a short Ok Ma’am
video about the water cycle
DISCUSSION:
what a wheel does on a bike?
Student will say “go round
That’s correct, the wheel on and round Ma’am”
a bike goes round and round.
Just like the song wheel on Yes Ma’am
the bus. You know that song?
water goes in a cycle just like
a wheel goes around and
around.
What is water cycle?
The water cycle describes Some students raise their
how water is exchanged hands
(cycled) through Earth's land,
ocean, atmosphere and
organism like plants and
animals.
The water cycle consists of
three major processes:
A. Evaporation
B. Condensation
C. Precipitation
Evaporation is the process of
a liquid's surface changing to
a gas. In the water cycle,
liquid water (in the ocean,
lakes, or rivers) evaporates
and becomes water vapor.
The water cycle's
evaporation process is driven
by the sun. As the sun
interacts with liquid water on
the surface of the ocean, the
water becomes an invisible
gas (water vapor).
Evaporation is also
influenced
by wind, temperature, and
the density of the body of
water.
Condensation is the process
of a gas changing to a liquid.
In the water cycle, water
vapor in the atmosphere
condenses and becomes
liquid.
Condensation can happen
high in the atmosphere or at
ground level. Clouds form as
water vapor condenses, or
becomes more concentrated
(dense). Water vapor
condenses around tiny
particles called cloud
condensation. Clouds at
ground level are called fog or
mist.
Like evaporation,
condensation is also
influenced by the sun. As
water vapor cools, it reaches
its saturation limit, or dew
point. Air pressure is also an
important influence on the
dew point of an area.
Unlike evaporation and
condensation, precipitation
is not a process. Precipitation
describes any liquid or solid
water that falls to Earth as a
result of condensation in the
atmosphere. Precipitation
includes rain, snow, and hail.
Precipitation is one of many
ways water is cycled from
the atmosphere to the Earth
or ocean.
Did you understand our
lesson class?
If you really understand our
lesson lets recall.
Yes Ma’am
It is the process of a liquid's
surface changing to a gas?
Ok Ma’am
Very good, how about the Evaporation Ma’am
process of a gas changing to
a liquid?
Then how about the
precipitation? Condensation Ma’am
Wow very good. You really describes any liquid or solid
listen when I was discussing water that falls to Earth as a
result of condensation in the
PRESENTATION OR GAMES atmosphere
Group yourselves into two
(2) group, start counting 1-2,
1-2
This activity is called
“Paunahan sa Pagbuo”
All of you should participate
for I will give extra points for
those who will participate in
this activity.
Each group will choose their
leader
A letter A-Z is being attached
on the board. Every question
has a corresponding letter,
each group leader assigned a
member to answer the
question and get a letter on
the board. Each group should
Paunahan sa Pagbuo
Gets?
Ok, let’s begin our play
Yes Ma’am
V. Assessment:
During Guided practice: Look for students who are pointing at the correct picture
on the diagram.
During Independent practice: Your students should be able describe the water
cycle verbally as they point to the pictures on their diagram.
VI. Review and closing:
Ask the students to describe evaporation, condensation, and precipitation.
Ask the students to think of ways they will tell their parents about the water
cycle.
