PLAN
Subject :Physics
Grade/
Semester : X/2
School : SMA Negeri 3 Semarang
Topic : Optic
Time
allocation : 10 minutes
COMPETENCY STANDARD : Applying the principle of optical
instruments
BASIC COMPETENCE : Analyzing optical
instruments qualitatively and
quantitatively
INDICATORS: Describe the function and the optical devices
OBJECTIVE :
1.
students can understand the optical
device
2. students can explain the function of parts of the optical devices
LEARNING METHOD/
MODEL:
Methods: lectures and discussions,
Model: cooperative learning
Model: cooperative learning
MATERIAL:
The optic
disc or optic nerve head is the location where ganglion cell axons exit the eye
to form the optic nerve
The optic disc has a center
portion called the "cup" which is normally quite small in comparison
to the entire optic disc.
The macula is yellow in colour it absorbs excess blue and ultraviolet
light that enter the eye, and acts as a natural sunblock (analogous to
sunglasses) for this area of the retina.
Zonules are hundreds of
string like fibers that hold the lens suspended in position and enable it to
change shape for near or distant vision.
The sclera, also known as
the white or white of the eye, is the opaque, fibrous, protective, outer layer
of the eye containing collagen and elastic fiber.
LEARNING ACTIVITY:
Opening:
Ø Teacher say
hello, introduce themself,
pray, and to
check student attendance
Ø Apperception: at previous meetings we have
learned about the formation of
a shadow in the
mirror and lens. do you think of the
inside of the human eye-like
lenses or mirrors?
Ø Motivation: nah, that's what we learned
today, that is about our eyes
Ø after learning about the parts and functions
of the eye, you are expected to
.......................................
Main:
a. Eksploration:
we can see because we have eyes. Riska now you come to
the front the class. You see
Dito then explain
what you see. Dito is real? Dito is upside down? so
do you think the human eye- like mirrors or
lenses??.
b. Elaboration:
So that more students understand, I will form a discussion group. in my right hand is the group number
one and then my left hand is the group
number two. Discuss with your friend
about function of the eye! And explain your answers in front of class.
c. Confirmation:
Teacher
give a confirmation about the correct answers.
Closing:
Give
conclution, homework.
