BRIEF INTRODUCTION
Lesson
1 Seed Germination and Growth
Let’s Learn
How does a plant grow? How does a seed turn into a plant? Seeds grow into
new plants. For a seed to grow into a plant, it must first sprout, or germinate.
Germination is the process in which the embryo or baby plant gets energy from the
stored food in the seed and starts to grow.
When a seed is
exposed to a
proper growing
condition, it
starts to take in
water and
oxygen through
its seed coat.
A root then
starts to grow
downward,
to absorb
more water
and nutrients.
This first root is
called
radicle.
A shoot
emerges and
grows
upward,
catching light
and air. This
shoot is called
hypocotyl,
and it makes
the plant’s first
leaves called
plumule.
.
During
germination,
the hypocotyl
pulls the
embryo’s
cotyledons out
of the ground
with it. But other
plants remain
their cotyledons
in the soil.
The
cotyledons
will wither
when the
plant has
grown its
first true
leaves.
Do you know that all seeds require oxygen, water, and the proper
temperature range in order to germinate? Oxygen and moisture, initially
taken in through the seed coat and later by the root, help the seed get
energy from its food supply. Different types of seeds have specific
temperature requirements for germination. Many seeds also require
proper light conditions to germinate. Some require light, while others are
inhibited from germinating by light.

7
Plants are living things. They grow and reproduce like any other living things. They
follow a cyclic process of starting a new life, growing, and then coming back to the starting
stage (reproducing). Plants start their life from a seed and grow-up to become a mature plant.
ACTIVITIES
Activity 1.1: Grow A Seed Jar
(This activity is optional)
What I need:
paper towels
water
seeds (mongo or any available seed)
large jar
What to do:
1. Fill the jar with paper towels. You can fold them and push them down into the
jar.
2. Gently water your seed jar to wet the paper towels. Be careful not to flood it.
3. Carefully push seeds down into the paper towels around the edge of the jar
so they can still be seen. Make sure they are firmly held in place.
ACTIVITIES
Activity 1.2: Arrange the stages of seed germination according to sequence by drawing
them in the box. Briefly describe what happens in each stage.

BRIEF INTRODUCTION
Lesson

Life Cycle of Selected Animals
(Complete and Incomplete
Metamorphosis)
Let’s Learn
Just like plants, animals also go through changes as they grow. Some animals
and other insects go through three stages and others go through four stages.
Metamorphosis is a biological process by which an animal physically develops
after birth or hatching. It is part of the life cycle of most insects. The term metamorphosis

1. Germination is the process in which the embryo or baby
plant gets energy from the stored food in the seed and
starts to grow.
2. All seeds require oxygen, water, and the proper
temperature range in order to germinate.

refers to the way insects develop, grow, and change form, usually accompanied by change
of habitat or behavior.
Most insects go through the four stages of metamorphosis such as butterfly, mosquito,
and housefly. Some animals such as cockroach and grasshopper go through only three
stages in their life cycle. Let’s explore more on the life cycle of these insects.
Life Cycle of Animals (Complete Metamorphosis)
Life Cycle of a Butterfly
Life Cycle of a Mosquito
Eggs are laid on plants
by the adult female
butterfly. These plants
will then become the food
for the caterpillars.
The adult butterflies
have long legs, long
antennae, and compound
eyes. They can also fly
by using their big and
colorful wings.
When the caterpillar is
developed and stops
eating, it becomes a
pupa. The pupa of
butterflies is also called a
chrysalis.
The next stage is the
larva. As the caterpillar
grows it breaks its skin
and sheds it about 4 or 5
times. Food eaten at this
time is stored and used
later as an adult butterfly.
Eggs are laid one at a
time or attached together
to form "rafts." They float
on the surface of the
water.
The larva lives in
the water and
comes to the
surface to breathe.
Larva sheds (molt)
its skin four times,
growing larger after
each molt.
The pupa stage is a
resting, non-feeding
stage of development.
The adult rests on
the surface of the
water for a short
time to allow itself
to dry and all its
body parts to
harden. The wings
have to spread out
and dry properly
before it can fly.
egg
larva
pupa
adult

10
Life Cycle of a Housefly
Life Cycle of Animals (Incomplete Metamorphosis)
Life Cycle of a Cockroach
Within a day, housefly
eggs hatch into larvae,
also known as
maggots. Maggots are
legless, white insects that
feed from the egg-laying
site for three to five days.
A female housefly
lays eggs in dark
surfaces such as
compost, manure,
and other
decomposing
organic material for
egg laying.
Pupa’s hard, brown
shells protect the
inactive, developing
flies.
After three to six days,
the pupa develops legs
and wings, and emerge
as an adult housefly.
The adult female
cockroach lay eggs.
They produce between
10 and 40 eggs at a time,
which they carry in
specialized cases.
When they turn into fully
developed adults, their
color becomes darker
and harder. Their wings
are also fully developed
during this stage.
Newly hatched
cockroaches come out
from eggs as nymphs.
During this stage, the
insects grow by shedding
their skin until they
become an adult. This
process is known as
molting.

Life Cycle of a Grasshopper
ACTIVITIES
Activity 2.1: Arrange the pictures of the different insects/animals to show the
correct order of stages in their development. Draw them using the format
provided in the next page.
Life Cycle of a Butterfly
Life Cycle of a Mosquito
Life Cycle of a Housefly
When an egg hatches, a
small grasshopper comes
out called a nymph.
During the nymph stage,
the insect sheds its outer
body covering to grow.
Female grasshoppers lay
eggs. Eggs are placed in
a pod which contains up
to 100 eggs inside. Eggs
are placed securely
inside the mud.
The nymph becomes
an adult. It can take up
to two months for a
grasshopper to complete
its life cycle depending
on the right conditions.

1. All living things go through changes as they grow and
develop. The process where organisms change and
develop is called metamorphosis.
2. Most insects go through the four stages of
metamorphosis such as butterfly, mosquito, and
housefly. These insects go through complete
metamorphosis.
3. Some animals such as grasshopper, dragonfly, and
cockroach only go through three stages in their life cycle.
These insects go through incomplete metamorphosis.
5. Once glue has dried up, label each section with the stages: 1. Egg 2. Nymph 3. Adult
6. Draw arrows from one stage to the next. This will show the progression of the
organism’s growth.

BRIEF INTRODUCTION
Lesson
3 Life Cycle of Animals (Egg Laying)
Let’s Learn
Name the animals in the box below.
Do these animals differ from each other?
Do these animals have something in common?
What do they have in common?
Animals that lay eggs such as fish, birds, turtle, and frog are called egg-laying
animals. Here are some of the stages of development in the life cycle of some egg
laying animals.
Life Cycle of a Chicken
Chicks are furry. They
peck at the ground to find
food that is good for
them.
Adult chickens begin the
life cycle again. Male
chickens are called
roosters and female
chickens are called hens.
After about 21 days, the
chick has grown big
enough to break the shell
and hatch. This period is
called hatching.
As soon as the chicken
lays the eggs, it sits on
them to keep them warm.
The embryo or baby
chick eats the yolk for
food as it grows.

15
Life Cycle of a Frog
ACTIVITIES
Activity 3.1 Arrange the pictures of the different animals to show the correct
order of stages in their development. Write your answers using the format below.
A. Life Cycle of a Chicken
B. Life Cycle of a Frog
A frog lays a lot of eggs
at one time. The eggs are
covered with a jellylike
coating.
The second stage of the
frog life cycle is the
tadpole. Hatched
tadpoles have gills for
breathing in the water.
They have a tail, but no
legs.
After a few weeks, the
tadpole has only a small
tail and becomes a
young frog. Soon, it will
leave the water, only to
return again to lay more
eggs.
Once the lungs form and
begin to work, the gills
and tail disappear. The
adult frog is now ready
to live on land.

BRIEF INTRODUCTION
Lesson
4 Life Cycle of Humans
Let’s Learn
Humans also go through stages of growth and development. You started out
as a tiny egg inside your mother’s womb. Here are the stages in the human
life cycle.
Birth is the start of human life as a
physically separate individual. A
period when a baby is born.
Infancy is a period from birth through
the first year of life. The infant is
completely dependent to its parents
or guardian in order to survive.

18
Childhood is a period between ages 1 to
10. During the first 2 years, the child is
called a toddler. The child learns how to
walk, talk and be more independent.
During this period, the child can easily
learn habits and behaviors.
Adolescence is period between ages 12 and 18.
It is considered as a critical turning point because
it is when puberty takes place. Boys’ voices
change and girls experience a monthly cycle
called menstruation.
Adulthood is a period from age 18
throughout old age. It is the stage when
human beings are fully grown and becomes
fully independent.
