MOTIVATION
(The teacher will ask
some questions)
(The teacher post a
picture of a seed)
“Have you seen a seed?”
“Yes, ma’am!”
“What kind of seeds
do you know?”
(Pupils will respond)
(The teacher will
call one by one)
“What do you notice about those seeds?”
“They differ in size
and shape.”
ACTIVITY
“Now,
I have here a short story and I
want
you to listen carefully and we will
answer
few questions later.”
(The
teacher will present
“The
Tiny Seed”by Eric Carle)
“Did
you enjoy the story?”
“Yes,
ma’am!”
“Are
you ready to answer some questions?”
(Pupils will respond)
Discussion Questions:
·
Who
is the main character in the story?
“The Tiny Seed”
·
What
blows the seeds?
“Air!”
·
Did
the tiny seed fell on the ground
during
autumn?
“No, ma’am”
·
Why
do you think the Tiny Seed
was the last one who grew?
(Pupils will respond)
ANALYSIS
(The teacher will ask few
more questions)
·
What
approach would you use to
help the tiny seed grow?
·
What
do you think is the purpose of the
flower losing its seeds?
ABSTRACTION
“Seeds have been an important development in
the
reproduction and spread of flowering plants,
Seeds, though too small, they have their own
parts,
like an ordinary living thing.”
“Today, we are going to learn the
different
parts of a SEED.”
“A
seed only develops its parts only when it
undergoes
a process called SEED GERMINATION.”
(The
teacher will post the
Definition of GERMINATION)
(She
will let the pupils read it loud)
“GERMINATION is the process by which plants,
emerge from seed and begin growth.”
“Okay, thank you.”
“I have here an illustration of a
seed during germination.”
(The
teacher will post the
illustration on the board)
(The
teacher will the illustration)
“These are the parts of a SEED
during
germination.”
PARTS
OF A SEED
·
EMBRYO
– a very young plant
From which a new plant grow
under proper conditions
·
RADICLE –in a dicot is the embryonicroot.
“Can you point out where is the
radicle in the illustration?”
(A pupil
will go in front and point
out Radicle in
the illustration.)
“Within the seed, there is usually a
store of nutrients for the seeding that
will grow from the EMBRYO.
The seed has its own food supply
– called the EPICOTYL and
COTYLEDONS.”
·
SEED COAT – develops from tissue,
originally
surrounding the OVULE.
The
seed coat helps protect the embryo.
“So,
where’s the seed coat in the illustration?”
(A
pupil will respond)
“Okay, thank you. So you
see,
the SEED COAT is the outer
part of a seed.”
“Any other question?” “None,
ma’am!”
“Did you understand the lesson?”
“Yes,
ma’am!”
“Again, what is a very young
plant
From which a new plant grow
under
proper conditions?”
“AN EMBRYO”
“What about the embryonic
root in a dicot seed?”
“RADICLE!”
What do you call the seeds own food supply?” “EPICOTYL AND COTYLEDON”

and growth.
2. Where does a flowering plant start?
3. What is a primary root?
