1.
Core
Concept
At the end of a 50-minute lesson, at least 90 % of the
students should be able to :
-
Differentiate the growth of embryonic in Frog, Chicken and Human
-
Begin to understand the growth and developmental stages of Frog
-
Begin to understand the growth and developmental stages of Chicken
-
Begin to understand the growth and developmental stages of Human
2. Purpose
- Understand and apply knowledge of
factual, conceptual, procedural in science, technology, art, culture, and
Humanities in a specific field of study in accordance with their aptitude and
interest in solving problems.
- Student are expected to compare the difference between growth and developmental stages of Frog, Chicken and Human.
-
Develop
a behavior (be honest, discipline, responsibility, caring, polite, friendly,
mutual cooperation, peace-loving, responsive and pro-active) and showed the
attitude as part of class
learning.
3. Content
a. 3
steps embryonic development of frog:
-
Egg:
·
Frog lays many eggs at one time
·
The eggs are covered with a jellylike
coating.
-
Tadpole:
·
have
gills for breathing in the water,
·
It has a tail, but no legs.
·
As
a tadpole grows, lungs begin to form.
·
Back
and front legs begin to grow. These
parts allow the adult frog to live on land
-
Adult frog:
·
The lungs form
·
Frog is now ready to live on land
- Metamorphosis: is
the changes that a frog goes through during its life cycle.
b. 3
weeks growth embryonic of chicken:
-
1st week:
·
Eyes
begin to form
·
Heart
begins to beat
·
Formation
of reproductive organs
-
2nd week:
·
Feathers
begin forming
·
Beak
starts to harden
·
Toes
fully formed
·
Embryo
turns head towards blunt end of egg
-
3rd week:
·
Small
intestines taken into body
·
Fully
covered with feathers
·
Growth
nearly complete
·
Yolk
sac drawn into body
·
Embryo becomes chick and starts breathing air in air cell of egg
·
Chick
hatches
c.
Embryonic development of human:
- Gametogenesis: is
a process by which the diploid germ cells undergo a number of chromosomal and
morphological changes (meiosis) form mature haploid gametes.
-
Fertilization: Activates
egg & brings together the nuclei of the egg and sperm. This step produce
zygote.
- Cleavage: Partitions the zygote into many smaller cells through Morula, Blastula, Gastrula.
-
Morula: Early
stage embryo consisting of cells in a solid ball formed by cleavage.
-
Blastula: A hollow sphere of cells
formed by cleavage of the morula. Contains the blastocoel that is fluid-filled.
It has blastopore where the gastrulation begins.
-
Gastrula: Transformation of the
blastula into an embryo possessing 3 germ layers, ectoderm, mesoderm, endoderm.
- Neurula: Neurulation occurs. The neural ectoderm tube is differentiated into
neural tissue which develops into the brain and spinal cord is formed.
- Organogenesis: The process by which the three germ tissue layers of the embryo develop
into the internal organs of the organism body.
- Implantation: Embedding of blastocyst into
uterine lining begins at day 7
· Trophoblast
forms syncytial trophoblast: erodes into endometrium
· Cellular
trophoblast: carries
nutrients to inner cell mass
· Lacunae
and primary villi formed by trophoblast
- Placentation: Development of placenta from edges of
blastocyst
· Placenta: Organ that forms from the chorion and the
endometrium and allow the embryo/fetus to exchange nutrients and waste.
2.
Activity
a. Preliminary Activities (13.00 - 13.10)
1. Class
Opening and checking for student attendance
2. Teacher will review the previous topic
to the students
3.
Teacher tell students the motivation/apperception that all living things produce offspring
(reproduce), but life begins in different ways for different animals.
b. Core
Activities (13.11 - 13.40)
1.
Teacher show the Newborns video of frog, chicken and human and encourage them
to pay close attention to how the birth process varies from species to species.
If possible, have them to watch the clip more than once.
2. Teacher
explain through the PowerPoint Presentation about Embryonic Development of Frog,
Chicken and Human
3. Student
and teacher conclude the Embryonic Development of Frog, Chicken and Human.
4. Student
works in group to answer short quiz by the teacher and collect the right answer
together.
c. Class
closing (13.41 - 13.50)
1. Closing
for class
2. Class
documentation
3.
Media
-
Book, Pictures, Videos, PowerPoint
presentation and LCD Projector
4.
Evaluation
Teacher will give a short quiz for each student groups (works in group).
Directions:
-
Please sit in group then write your group number and
member name (using alphabet) on this paper.
-
Match the vocab and the meaning by fill the blank side
with letters.
