III. Learning Activity
a. Engage
1.Drill
Yes or No
- The teacher will show a picture that show’s use of water they will answer yes or no.
2. Review
The teacher will ask the student if they remember the lesson yesterday.
Give some example.
b. Exploration
Activity: Video presentation ( Source of water )
Answer the following question based on the video presentation:
1. Is the water is important to our life?
2. where does water came from?
3. How can we get the underground river?
4. How can we save water?
c. Explanation
Water comes from different sources of water. It may come from open or closed source.
The three different kinds of water depends on its source. The three different kinds of
water are seawater, freshwater, and groundwater.
1. Seawater is a salty. It contains plenty of salt. It is found in the
seas and oceans. Seawater is also called hard water.
2. Freshwater is also called surface water. Unlike the seawater, It
does not contain salt. This found in the open but small bodies of
water like rivers, lakes, creeks, and ponds. Surface water comes
mostly from rain. Rainwater flows from land into streams and
rivers. In cold countries, it also comes from snow, Great
qualities of snow accumulate on highlands and mountains
during winter. In spring, the snow melts and runs off into
surface water.
3. Groundwater is found beneath the earth surface. It comes from
water that seeps into the ground. These accumulate in the
underground layer called water table. Groundwater is the safe
source of water. It is considered the cleanest water and
contains plenty of dissolved minerals which the human body
needs. Springs are openings of the groundwater directly to the
earth's surface.
Other sources of water are clouds, icebergs, and clouds comes from evaporating
water, Glaciers and icebergs are solid water found only in a very cold countries and contain about two-
thirds of the earth's freshwater.
d. Elaboration
Water can be used for direct and indirect purposes. Direct purposes include bathing,
drinking, and cooking, while examples of indirect purposes are the use of water in
processing wood to make paper and in producing steel for automobiles. The bulk of the
world's water use is for agriculture, industry. and electricity.
e. Evaluation
ACTIVITY:
1. What are the 3 different sources of water?
2. Name some of the places where the water is used.
3. How is water used in these places?
4. What are the sources of water supply in your barangay?
5. How is the water sources kept safe and clean?
