B. Analysis
If you notice our motivational activity,
everything is related to our lesson for this
day. The characteristics of various soil types
and the different sources of water suitable for
human consumption, as well as the importance
of water cycle.
We can now proceed to our discussion for
today. Is my screen visible?
Ok thank you. Now, can someone read the
definition of what soil is?
Yes Ma’am.
(The student clicks the raise hand button)
<Thank you. So, soil is the thin layer of
material covering the earth's surface and is
formed from the weathering of rocks. It is
made up mainly of mineral particles, organic
materials, air, water, and living organisms4
all of which interact slowly yet constantly.
In addition, soil have different types and
their characteristics.
Can someone give me at least 3 examples of
soil types?=
Excellent. Soils vary enormously in
characteristics, but the size of the particles
that make up a soil defines its gardening
characteristics. So, today, I am going to
discuss 6 types of soil and their
characteristics.
The loose upper layer of the Earth's surface
where plants grow is known as soil. Soil is
made up of organic matter (dead plants and
animals) as well as shattered rocks and
minerals.
(The student clicks the raise hand button)
<Ma’am, loam, sand, and clay.=
First is clay soil. Clay soil is a heavy soil
type that benefits from high nutrients. Clay
soils remain wet and cold in winter and dry
out in summer. These soils are made of over
25 percent clay, and because of the spaces
found between clay particles, clay soils hold
0
0
a high amount of water.
Second is sandy soil. Sandy Soil is light,
warm, and dry and tends to be acidic and low
in nutrients. Sandysoils are often known as
light soils due to their high proportion of sand
and little clay (clay weighs more than sand).
These soils have quick water drainage and are
easy to work with.
Third is silt soils. Silty soil is slippery when
wet, not grainy, or rocky. The soil itself can
be called silt if its silt content is greater than
80 percent. When deposits of silt are
compressed and the grains are pressed
together, rocks such as siltstone form. Silt is
created when rock is eroded, or worn away,
by water and ice. Do you have question
class?
Fourth is loam soil. Loam soils contain sand,
silt and clay in such proportions that
stickiness and non- adhesiveness are in
balance - so the soils are moldable but not
sticky. Loams are the "friendliest" soils to
cultivate. Clays can absorb and hold onto
large amounts of water because of their sheet
structure and large surface area.
<No Ma’am.=
Fifth is the peat soil. Peat soils are mainly
organic matter and are usually very fertile
and hold much moisture. They are seldom
found in gardens.
And last is chalky or lime-rich soils. It is
Chalky soil is comprised mostly of calcium
carbonate from sediment that has built up
over time. It is usually shallow, stony, and
dries out quickly. This soil is alkaline with
pH levels between 7.1 and 10. In areas with
large deposits of chalk, well water will be
hard water.
Now, did you understand the different types
of soil as well as their characteristics?

I’m glad to hear that all of you understand
the lesson. Now, we are going to discuss the
use of water in our daily living and the
importance of water cycle.
<Yes Ma’am=
In your own opinion, how do we use
(The student clicks the raise handbutton)
water? Yes ___ ?=
<Very well said
Ma’am, water can be used
drinking.
.=
for
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.=
Is there anyone in this class who knows
where we
can get water? Give me at
(The student clicks the raise handbutton)
least one.= <Very good
Ma’am, in the river.
.=
<All of the water that we use comes from
local lakes, rivers, streams, or underground
aquifers, depending on your city and state.
How we use water depends onthe purpose at
hand.=
Water can be used in various ways, such as
in household water uses. Common
household uses consume a lot of water. It
may take between 30 and 40 gallons for one
bath while the average toilet uses about 5
gallons of water per flush. Much of our
residential freshwater resources are also
used for watering lawns, flower beds, and
vegetable gardens, as well as washing cars,
etc.

Next is communities. Cities use water for
firefighting, street cleaning, and watering
public areas such as parks, grass, trees,
shrubs, and flowers. Water is also used to fill
public drinking fountains, including those at
schools and libraries. All of the different
businesses in your community also use large
amounts of water.
Another example is farming. The amount of water
needed to run a farm is tremendous. When we
think of water on a farm, we think of watering
crops; but the amount of water needed on a dairy
farm is just as large. Chickens, pigs, sheep, and all
the other animals in a farmyard need drinking
water to stay alive. Food must be grown for them
to eat, and water is also required in the cooling
systems used to keep the production of meat
fresh. Most of the water used on farms is
used for irrigation.
Moreover, water is also essential in industry,
as it is heated and the steam is used to run
machinery. Water is used to cool hot metal
such as in the production of steel. Water is
also an important element in many products
like chemicals, drugs, lotions, shampoos,
cosmetics, cleaners, andbeverages. Water is
used in processing food and in innumerable
factories and industrial processes including
the manufacturing of paper. Water used in
processing foods and beverages must be
absolutely clean, while other industries such
as a manufacturing plant may use a lower
quality of water.
Water plays a significant role in our daily
life. So, we should conserve water. Failing to
conserve water caneventually lead to a lack
of an adequate, healthywater supply, which
can have drastic consequences in rising
costs, reduced food supplies, health hazards,
and political conflict. Did you understand
my dear students?
<Yes teacher.=
Moving on to our next lesson. The
0
0
importance of water cycle. But before that,
can someone explain what a water cycle is?
Just a brief or simple explanation.
(The student clicks the raise hand button)
That’s correct. Thank you so much
.
<Ma’am, the water cycle is simple circular
cycle of evaporation, condensation, and
precipitation.=
The water cycle is an extremely important
process because it enables the availability of
water for all living organisms and regulates
weather patterns on our planet. If water didn’t
naturally recycle itself, we would run out of
clean water, which is essential to life.=
Water is necessary for sustaining life on
Earth, and helps tie together the Earth's
lands, oceans, and atmosphere into an
integrated
system.
Precipitation,
evaporation, freezing and melting, and
condensation are all part of the hydrological
cycle - a never-ending global process of
water circulation from clouds to land, to the
ocean, and back to the clouds. This cyclingof
water is intimately linked with energy
exchanges among the atmosphere, ocean,
and land that determine the Earth's climate
and cause much natural climate variability.
The impacts of climate change and
variability on the quality of human life occur
primarily through changes in the water
cycle.=
<The major physical components of the
global water cycle include the evaporation
from the ocean and land surfaces, the
transport of water vapor by the atmosphere,
precipitation onto the ocean and land
surfaces, the net atmospheric transport of
water from land areas to ocean, and the return
flow of fresh water from the land back into
the ocean. The additional components of
oceanic water transport are few, including
the mixing of fresh water through the
oceanic boundary layer, transport by ocean
currents, and sea ice processes. On land, the
0
0
situation is considerably more complex and
includes the deposition of rain and snow on
land; water flow in runoff; infiltration of
water into the soil and groundwater; storage
of water in the soil, lakes, and streams, and
groundwater; polar and glacial ice; and use
of water in vegetation and human activities.

ocean, land, mountains, and rivers returning

precipitation, condensation, evaporation,

<Alright! Do you have questions my dear
<Nothing Ma’am.=
students?= <
That’s great. We just learned a lot about the
various types of soil and its characteristics,
the use of water, and the importance of water
cycle in our lives.

(The student clicks the raise handbutton)
<Ma’am, water is the basic necessity for the
functioning of all life forms that exist on earth.
It is safe to say that water is the reason behind
earth beingthe only planet to support life.
Thisuniversal solvent is one of the major
resources we have on this planet. It is
impossible for life to function without water.=
