The Importance of Water Cycle
IV. LEARNING PHASES AND LEARNING ACTIVITES
A. Introduction (Time Frame: Day 1)
The water part of the earth is called hydrosphere or “water sphere”. This covers three-fourths of its
surface. Therefore, water covers a larger area of its surface than land. That is why the earth is called “ the
blue planet”. Water gives the earth its characteristics of blue color as seen from outer space.
Water continuously moved in the earth’s surface in a process called water cycle. The water cycle
has four processes. These are:
1. Evaporation- The sun heats up bodies of water (such as lakes, rivers and oceans). Water turns to
vapor when heated and goes up into the air. Plants help in putting water back to the air. Plants
remove water from their bodies through transpiration. The water that leaves plant bodies goes to the
air too.
2. Condensation happens when cool air changes water vapor back to liquid water and form clouds in
the sky. This is the opposite of evaporation.
3. Precipitation happens when too much water has condensed; clouds get heavy and water falls as
rain. This is precipitation. In some countries water falls as sleet, snow or hail.
4. Collection- When it rains, water goes back to the bodies of water. Some water also goes to the soil.
The water in the soil is absorbed by the plants. Once collected, it goes to the bodies of water and
undergoes the process of evaporation. On the other hand, water absorbed by the plants undergoes
transpiration and will start the cycle again.
Although there is a continuous cycle of water, you might wonder if there will come a time when we
will run out of water. Do you know that about 97% of the water found in our surrounding is salty? Thus, only 3%
of this water is fresh or potable. This very small amount of fresh water is 67% locked in the form of ice mainly
found in Greenland and Antarctic. Therefore, only about 1% of freshwater is found in rivers, lakes, ponds, and
in the atmosphere in the form of water vapor.

Development (Time Frame: Day 1-2)
The activity that you are going to perform will help you describe the importance of water cycle.
Learning Task 1. Prepare the materials listed below. You may ask the help of your parents/guardians or any
adult members of the family if needed.
IV. LEARNING PHASES AND LEARNING ACTIVITES
Title: “How Important I Am in the Environment?”
Materials:
Picture, bond paper, ballpen
Procedures:
1.
2.
3.
4.
Study the illustration of a water cycle below.
Ask any members of your family especially the older ones to have a brainstorming about it.
Share ideas about the importance of water to man, animals and plants.
Write your ideas in a bond paper.
Questions:
1. What does the illustration show?
2. What is its importance to man? plants? animals?
3. Can life and other environmental processes continue without the water cycle? Why or Why not?
4. Do you think balance in nature will be achieved if water cycle processes are not complete? Why do
you think so?
5. Why is water cycle important?
B. Engagement (Time Frame: Day 3)
Now that you are familiar with the importance of water cycle, the next activity will help you trace the
water cycle.
Learning Task 2
Complete the concept map to show the correct cycle of water.
Water vapor from the atmosphere
changes to liquid water again to
form clouds in the process called
condensation
As the sun rises, water from the
oceans and land evaporates and
changes to water vapor through
the process of evaporation.
IV. LEARNING PHASES AND LEARNING ACTIVITES
Learning Task No. 3.
List down the effect of Water Cycle on Living things.
Good Effects
Bad Effects
C. Assimilation (Time Frame: Day 4-5)
Learning Task No. 4.
Construct a model of a water cycle. Write the things that you need and the steps that you have to do
You may use indigenous or recyclable materials in your project.
