THIRD QUARTER
MODULE NO. 1: LIVING THINGS
AND THEIR ENVIRONMENT
Lesson 1: Animal and Plant
Adaptations
At the end of this module, you should be able to learn
different body parts and structures of animals and plants and
how they use these in order for them to survive and live in their
habitat for you to realize that helping conserve their habitat
helps these organisms adapt more and live longer. Specifically,
you are expected to:
1. identify the body structures of the animals for adaptation;
2. infer that the body structures of the animals help them to adapt
and survive in their particular habitat;
3. identify the specialized structures of terrestrial and aquatic
plants;
4. compare the stages in the life cycle of organisms; and
5. create a Habitat Conservation Plan showing/explaining the
effects of environmental destruction to the habitat of the
animals and plants.
The competencies above will help you become a young
environmentalist concerned of preserving and saving the
natural habitat of animals and plants.

ROLE OF PARENTS
Monitor the students in checking the E-desk
posts for important announcements and after-
class activities to be done.
Guide the students to fully understand the lessons.
Supervise the students in performing/accomplishing
the given written activities and outputs.
Hello, Grade Four! It’s me, Agham!
I hope that you have learned a lot from the
previous lessons that you took with your teacher.
As you can see, I brought few of my friends
with me today. Your teacher and I will introduce you
to two Kingdoms of Life – to the world of animals
and plants. Are you as excited as I am to learn more
about these two kingdoms?
Come one, let’s get started!
Discovering the World of Science 4 |Third Quarter| Module 1 | Page 2
I know that many of you are into animals and
plants. Let us know what you know about them. Try
answering these questions.
Good luck, Grade Four!
NOTE: Since printing of the module is NOT required, answer the
activities in your interactive notebook. Checking is during the
F2F class.
Write TRUE or FALSE.
_______1. Mimicry is a way of how some animals adjust to their
environment by copying the colors and/or shapes of other
organism.
_______2. Different animals live in different places.
_______3. Habitat is a place where a certain organism lives.
_______4. Organisms like animals have to satisfy their needs such as
food, water, shelter, air and space so that they can survive
well.
_______5. Adaptation is how organisms adjust to their environment so
that they can survive.
_______6. Terrestrial plants live on land.
_______7. All plants need sunlight, water, air, and suitable environment
to grow.
_______8. Aquatic plants survive in water.
Discovering the World of Science 4 |Third Quarter| Module 1 | Page 3
_______9. Plants need sunlight, carbon dioxide and water to make their
own food through photosynthesis.
_______10. All plants have structures that help them adapt to their
particular environment.
Now, let us learn some more things about animals
and plants. Study the concept maps and diagram below that
summarize what is in stored for you in this module.
And also, make sure to take note and remember
everything that you will learn from your teacher during your
synchronous classes.
Happy learning, Grade Four!
TAKE NOTE:
terrestrial animals – animals that live on land (desert, grassland,
forest, polar areas)
aquatic animals – animals that live in water (freshwater like river or
lake, saltwater like sea or ocean)
REMEMBER THE FOLLOWING:
Both terrestrial and aquatic animals have structures (body parts)
that help them adapt to their environment.
Their structures vary depending on the conditions of the place in
which they live in.
Some of the structures include the teeth, beak, body covering, legs,
odor or substance released. These help them for protecting
themselves, for hunting their food and for better movement.
Discovering the World of Science 4 |Third Quarter| Module 1 | Page 4
Some animals undergo metamorphosis. This is a process in which
animals change as they undergo different stages of growth. The
illustration below shows two kinds of metamorphosis: complete and
incomplete.
Discovering the World of Science 4 |Third Quarter| Module 1 | Page 5
Like animals, plants have structures that help them adapt and
survive in their environment. Both terrestrial and aquatic plants have
structures that help them get their basic needs (sunlight, water, carbon
dioxide and nutrients).
Examples of Body Structures of Plants:
A. For Protection
thorns, spines, prickles on the leaves or stems
toxins in the leaves, stems, or roots
B. For Reproduction
colorful petals of flowers
stigma and stamen of flowers
seeds of fruits
C. For Getting Their Basic Needs
to get sunlight – leaves, roots for attaching themselves on
branches, tall stems or woody vines
to get water – root system
Special Structures of Plants:
A. Root Systems – Most plants have deep root systems. Some plants
have shallow root systems. Few plants, called epiphytes, have
specialized roots to get nutrients from the air.
B. Specialized Leaves – Some plants have dry, waxlike leaves. Others
have drip tips. Most plants have smooth, shiny leaves. Few plants
have leaves that trap and digest insects.
C. Modified Stems – Some plants have modified stems called runner,
rhizome, tuber, bulb and sucker.
