STUDENTS’ ACTIVITY
A. Preliminar Activities
1. Greetings
Good morning students.
Good morning, sir Niel. Good morning
Classmates.
2. Energizer
Now, let us sing a song. Let us
Sing, “Science is Fun”.
(The students will sing.)
3. Checking of Attendance
Is there any absent in the class?
None, sir.
Excellent!
4. Setting of Classroom Rules
Before we start our lesson, let us
First recall our classroom rules. Who can
Give me the first rule?
Correct. What are the others?
Sit properly.
Be quiet.
Listen attentively.
Participate.
B. Developmental Activities
1. Drill

C. ELICIT
I have here several pictures of different
Organisms. I want you to tell me the number of
Parents needed to reproduce an offspring.
Starfish
Gumamela
1 parent
2 parents
Human
2 parents
Segmented worm
1 parent
Yeast cell
1 parent
Dogs
2 parents
D. Engage
Let us examine the following
Pictures of some organisms we saw
Earlier.
These are pictures of a starfish and a dog.
One of them needs 1 parent to reproduce
While the other one needs two parents.
Why do you think these happen?
Sir, maybe the dog can have
Two sexes while the starfish has only
One sex.
You have a point. What else?
(The students will give other answers.)
Do these organisms always look the same
Like their parents?
(The students will give their anwers.)
Why do you think these are possible?
(The students will give their answers.)
E. Explore
Now, we will have a trip inside the
Classroom. I will group you into five.
The classroom has five learning
Areas. Each of them offers a different topic
That you will observe and examine. Write
Your notes as you go on.
I will assign each group to a
Designated learning area. After 3 minutes,
You will proceed to the next learning area
Until you finish visiting all learning areas.
Before we do that, let us recall
The guidelines in doing an activity. What
Is the first step?
That’s right. What else?
Be cooperative.
Show respect to your groupmates.
Don’t disturb other groups.
Follow directions correctly.
Let us start the activity.
(Designated learning areas for the groups:)
Group 1 – Area 1
Group 2 – Area 2
Group 3 – Area 3
Group 4 – Area 4
Group 5 – Area 5
(The students will do the activity.)
Learning Area 1: Vegetative Reproduction
“Can You Grow Plants from ‘Eyes’?”
1. In this activity, a potato tuber was cut into pieces and was planted.
2. Observe and examine the changes in the tubers.
3. Where did the new plants come from?
4. How many parents did it need to reproduce new plants?
5. What plants reproduce in the same manner? Cite some examples.
Learning Area 2: Pollination
“Can You Grow Plants from ‘Dust’?”
1. Study the male and female parts of the flower. What qualities do
they have?
2. What does the stamen have? What do we call the dust-like
particles in it?
3. Touch the pistil. What does it feel like? Why do you think it is
sticky?
4. What process spreads pollen to other plants? What organisms aid
in this process?
5. How many parents are needed to reproduce?
Learning Area 3: Budding
“Can One Become Two?”
1. Using a compound microscope, study and examine the slides
with yeast cells.
2. Notice that there are smaller cells in the yeast. Those are called
buds. It detaches itself from the mother cell and grows into a
mature cell.
3. How many parents are needed to reproduce?
Learning Area 4: Internal Fertilization
“Sperm and Egg Cells”
1. Study the picture. Where does a sperm cell come from?
Where does an egg cell come from?
2. How many organisms are needed to reproduce an
offspring?
3. Does the offspring only have similarities in just one
parent? Support your answer.
Learning Are 5: Fragmentation
“A New Worm By Cutting?”
(Present a video clip about cutting a segmented worm into two parts.)
1. Observe and study the video clip. What organism is it?
2. What happened to the worm when it was cut?
3. What happened to the separated part of the worm?
4. How many parents are needed for the reproduction?
5. Does the offspring have similarities with the parent worm? Support your
Answer.
F. Explain
Let us examine and hear your
Observations in the activity.
Each group shall have a designated
Speaker to present what they’ve observed
In a learning area.
Each group will only present their
Observations in the first learning area that
They visited.
(The teacher will assist the learners in the
Presentation. The teacher will give the
Correct scientific term for every needed
Observation.)
Examples:
Pollination
Budding
Pollen
Stamen
Pistil
Reproduction
(The students will present their work.)
What have you observed in the
Parents of the different offsprings? Do they
Have the same number of parents?
Why does it happen?
That is correct. Does every offspring
Looked exactly the same like their parents?
Why do you say so?
No, sir.
Some organisms needed only one
Parent. Others need two parents
To reproduce.
No, sir.
The organisms that need 1 parent, such
as the segmented worm, looked alike
their parent. On the other hand, the
organisms with two parents got traits
from both parents.
Yes, that is right!
G. Elaboration
There are two kinds of reproduction.
Asexual reproduction needs one parent to
Produce an offspring.
Some examples of asexual
Reproduction are vegetative reproduction from
Potatoes, budding from the yeast cells and
Fragmentation just like what happened to
The segmented worm.
Offsprings from asexual reproduction
Looks the same with the parent organism.
Sexual reproduction requires two
Parents- a male and a female- to reproduce.
Examples of this process are pollination in
Plants and internal fertilization in humans.
Offsprings from sexual reproduction
Gets traits from both parents.
To further understand the lesson, let
Us have an activity. I will group you now into
Three.
I will give you an activity card and
Follow the directions in it.
(The students will do the activity.)
Group 1:
1. Make a Venn Diagram about Asexual
And Sexual Reproduction.
Show their similarities and differences.
Group 2:
1. Draw two organisms that undergo
Asexual reproduction.
Group 3:
1. Draw two organisms that undergo
Sexual reproduction.
Let us take a look in your
Works.
(The students will present their work.)
Let us recall our lesson today.
What are the two kinds of reproduction?
Correct! How many parents does
An organism need for an asexual and a sexual
Reproduction?
What can you say about the
Similarities of the offsprings to the parent
In an asexual and sexual reproduction?
The two kinds of reproduction are
Asexual and sexual.
An organism needs one parent for
Asexual reproduction while two parents
Are needed for sexual reproduction.
Offsprings from asexual reproduction
Looked the same with their parent. On
The other hand, offsprings from sexual
Reproduction gets traits from both
Parents.
Exactly.
H. Evaluate
Write AR if the sentences refer to an asexual reproduction and SR for sexual reproduction.
____1. Ginger and sweet potatoes can reproduce by planting their plant tubers in the soil.
____2. The male organism produces sperm cells and the female organism produces an egg cell.
____3. Lisa cut a worm into two pieces. She was shocked when she saw the two pieces move separately
and independently.
____4. Male elements of a flower releases pollen to a female element of the flower.
____5. Sponges have smaller parts that can grow and become a different organism.
Answers:
1. AR
2. SR
3. AR
4. SR
5. AR
I. Extend
Read the sentences below.
1. If a starfish loses a body part, it grows itself a new one. The separated part grows into a new
independed starfish. Why do you think this happened?
2. To produce desirable gumamelas, the farmer needs to propagate a good variety of the flowers. What
method can the farmer use? Support your answer.
