Teacher’s Activity
Student’s Activity
1. Prayer
“Class, please stand. Let us pray.
“For those Catholics, do the sign of the cross”
“Our Heavenly Father, we thank you for this new
day that you have given to us and for giving us the
gift of life that we able to continue our purpose.
Lord, we are asking for your guidance as we tackle
our lessons for today that we may able to
understand everything. We ask all these through
our Lord, Jesus. Amen”
“In the name of the Father and of the Son and of
the Holy spirit. Amen.”

“Ms. Beadle, are there any absentees for today?
Wow, very good! You are all present. So, give
yourself five claps.
No, Ma’am.
(students are clapping)
6. Review
“Last meeting, we have discussed about
Biodiversity. “Okay class as a review, what is
biodiversity? Yes, Nico?
Very good Nico. That’s correct.
What else, any other answers? Yes, Salome?
“Very good Salome!
“Ma’am, biodiversity is the shortened term or
expression for Biological Diversity.”
“Ma’am, biological diversity or biodiversity refers
to the variety of living things on Earth, ranging
from species to populations from different
1. Activity
“Now, let’s play a game. I will group you first into
two groups and I will read the mechanics of the
So, here’s the mechanics: Each group are provided
with an image puzzle. You are going to complete
the puzzle to make a picture. Then all the pictures
given must be put on the board, choose your
group representative and explain the work you’ve
made in front.
Okay, are you ready?
“Yes, Ma’am. We are ready.”
(They started playing)
2. Analysis
“Okay class, from the completed puzzle you see.
What have you notice or observed?
Yes, Michelle?
Yes very good Michelle? Okay what else can you
see in the picture? You raised your hand, Ruby?
Great! Correct Ruby.
Okay, when you look at the drawing what comes
to your mind? Yes, Kimberly?
Yes! You are correct Kim.
Okay, class what do you think is our lesson for
today? Yes, Maria?
“Ma’am, I can say that someone is drawing a
Ma’am aside from _____ and _____ they explain
earlier, I see also mountains, trees, rain water and
Ma’am it’s something like a cycle.
Ma’am, I think our lesson for today is about water
Yes! Maria, you are correct.
3. Abstraction
“So, class today we are going to discuss
Biogeochemical cycles focuses on water cycle.
What is biogeochemical cycles?
The ways in which an element—or compound
such as water, carbon, nitrogen, oxygen—moves
between its various living and nonliving forms
and locations in the biosphere. In order for the
living components of a major ecosystem (e.g.,
a lake or a forest) to survive, all the chemical
elements that make up living cells must be
recycled continuously.
Okay, did you already understand what is
biogeochemical cycle?
Do u have questions regarding biogeochemical
Very good. So, now let’s move on to Water cycle.
What is Water cycle?
Biogeochemical cycle is a circular system through
which some element is transferred between the
biotic (living) and abiotic (nonliving) components
of the biosphere.
The term biogeochemical is a contraction that
refers to the consideration of the biological,
geological, and chemical aspects of each cycle.
Yes, Ma’am!
No, Ma’am.
Water cycle, also called hydrologic cycle- it
involves the continuous circulation of water in
the Earth-atmosphere system. It is a complex
system that includes many different processes.
There are 5 major processes of water cycle? What
are those Chermie?
The major processes of water cycle are
evaporation, condensation, transpiration,
precipitation, and runoff.
Okay, let us tackle the first process. Yes, Cindy
what is evaporation??
Ma’am,Evaporation is the conversion of water
from a liquid into a gas.
Yes, very good. By evaporation, water in
the liquid state is transferred to the gaseous, or
vapour, state. Okay, what do you think is the
principal source of water vapour in the process of
evaporation? Yes, Rocco?
Ma’am, the principal source of water vapour is
Yes very good! Ocean is the principal source. So,
how evaporation occurs? Yes, Laiza?
Great! Yes correct.
Okay, next process, condensation. Yes, Liezl ?
Yes very good. As water vapor rises higher in the
atmosphere, it begins to cool back down. When it
is cool enough it forms into a cloud. The water
vapor condenses and returns to liquid water.So,
what happens next after the condensation occurs?
Yes, Almeer?
Moisture is transported around the globe until it
returns to the surface as precipitation.
Okay what is precipitation. Okay, Cherry?
Ma’am, evaporation occurs when sunlight warms
the surface of the water. The heat from the sun
makes the water molecules move faster and faster,
until they move so fast they escape as a gas.
Ma’am, Condensation is the conversion of water
from a gas into a liquid.
Ma’am by water transport. Water move through
the atmosphere, specifically from over the oceans
to over land.
Precipitationis transfer of water from the
atmosphere back to earth as rain.
Once the water reaches the ground, one of two
processes may occur; 1) some of the water may
evaporate back into the atmosphere or 2) the
water may penetrate the surface and
become groundwater.
Okay, groundwater either seeps its way to into the
oceans, rivers, and streams, or is released back
into the atmosphere through transpiration. Please
read Fretchel.
Transpiration is a transfer of water from plants
to the atmosphere. Transpiration is the
evaporation of water through minute pores, or
stomata, in the leaves of plants.
Then the last one. Almeer?
Runoffis the movement of landwater to the
oceans, chiefly in the form of rivers, lakes, and
The balance of water that remains on the earth's
surface is runoff, which go down into lakes, rivers
and streams and is carried back to the oceans,
where the cycle begins again.
Okay class, did you already understand what is
water cycle all about?
Yes, Ma’am.
4. Application
Very good. Last meeting, I told you to bring your
pencils and coloring materials, right?
Okay, good. To check if you really understand our
lesson. Get one short bond paper. Draw your own
illustration or diagram of a water cycle. Label it
using the 5 major processes. I will give you 10
minutes to finish it. You may start now.
(After 10 minutes)
Okay, time is up. Pass your work in front.
IV. Evaluation
Kindly get ¼ sheet of paper we will have a
short quiz. Get ready, I will going to read it
once. So, listen very carefully.
1. It is a circular system through which
some element is transferred between
2. It is a continuous circulation of water in
the Earth-atmosphere system.
3. It is the conversion of water from a
liquid into a gas.
