IV. PROCEDURES
A. Introductory Activity
Review:
Last time have learned about corals.
Let’s find out how far you have remembered
 Corals- living things or non-living things
 Corals- plant or animal
 Corals- vertebrate or invertebrate
Motivation
Where do corals live? What do you call the place where we can
see a lot of corals?

2. Sa inyong AP sa Grade 5, you have discussed about
CONTINENTAL DRIFT Theory of Alfred Wegener at Teoryang
Bulkanismo
Ang Pilipinas ay bahagi ng isang malaking tipak ng lupain na
tinatawag na Pangaea at dahil sa unti unting paggalaw paggalaw
ng kalupaan na siyang dahilan ng pagkakahiwahiwalay ng
malalaking tipak ng lupain sa daigdig.
Bailey Willis, a geologist, concluded that the Philippines was a
result of the eruptions of submarine volcanoes along the western
side of the Pacific basin and this results to the formation of coral
reefs.
Presenting the Lesson
What can you say about coral reefs?
What can you see in the coral reefs?
A coral reef is rich with marine life. It is a marine biome. It is
composed of non-living things and living things. The living part is
composed of different species like fish, sea grass, corals, sponges
and other marine animals.
B. Activity
Today let us distinguish the different interactions that happens in
the coral reefs.
How does the interactions interact in the coral reefs?
Provide activity sheets to the groups.
Directions: Match the pictures to the interactions:
Big fish eats small fish
different species living
sea grass living in the
corals
barnacles attached on skin
of turtles
Commensalism is an
interaction where
organisms live together
without harming one
another
Mutualism is an
interaction when both
organisms benefit in
the relationship
Competition is an
interaction wherein
organisms compete for
survival.
Predation is a kind of
interaction in which
one organism kills
smaller organisms for
food.
COI 8. Used effective strategies
for providing timely, accurate
and constructive feedback to
encourage Learners to reflect
on and improve their learning.
COI 1. Modeled effective
applications of content
knowledge within and across
curriculum teaching areas.

3. C. Analysis
Now let’s watch the video about coral reefs and the
interactions among living and non-living things in coral reefs
https://www.youtube.com/watch?v=k8bvXlTRBUM
 What are the 3 different types of coral reefs?
 What are the different interactions that happened in the coral
reefs?
 How does mutualism happen in the coral reefs?
Commensalism? Predation and competition?
 Why are coral reefs important in the marine biome?
 What tribe do you know that are known as sea tribes?
Badjao people are also called sea tribes because they are
fisherfolks. And they use spears to hunt for food. If you are
among Badjao tribe, how will take care of the coral reefs?
D. Abstraction
I learned that ….
The________________ serve as a breeding ground of marine life.
The factors that contribute to the reef formation are light
penetration, ______________, stable salinity and
_______________.
The________________, ________________and ________________
are categories of coral reefs.
_________________ is an interaction where organisms live
together without harming one another, for example, barnacles
attached to the skin of turtles without harming them. In
_________________both organisms benefit in the relationship.
For example, corals receive oxygen from the algae; the algae
get protection from them. ________________ is a kind of
interaction where one organism, the parasite, depends on
another organism for food, production and reproduction.
________________ is a kind of interaction in which one
organism kills smaller organisms for food. An example of this
is when a big fish eats a small fish.
E. Application
Identify the different types of reefs.
1. Reefs located close to shore, separated from land by
only shallow
2. Reefs found offshore and comprise a ring-shaped reef
enclosing a circular lagoon
3. reefs that stand between the open sea and a lagoon
Directions: Identify the interaction between the given pair of
organisms in column A and its interaction in column B.
1. sea urchin-corals A. mutualism
2. fish and jelly fish B. competition
3. tuna fish-blue marlins C. predation
4. clown fish-sea anemone D. commensalism

thinking, as well as other
higher order thinking skills.

Group 4
Directions: Read the paragraph and answer the questions
that follow.
Living things and non-living things interact with each
other in a Coral reef ecosystem. Coral reef is composed of
non-living components such as water and sand. It serves
as breeding place for fish, crustaceans, mollusks,
cnidarians, sponges and echinoderms. Their interaction
enables the survival of living things and affects non-living
things. Can you identify the living and non-living things in
Coral Reef Ecosystem? Discuss their interaction.
Group 5
Make a graphic organizer to answer the question below:
What are the living and non-living things found in the coral
reefs?
