Content Analysis terms Sclera, Cornea, Conjunctiva, eyeball, choroid, ciliary muscles, retina,
aqueous chamber, vitreous humour.
Facts 1) Eyeball has three layers.
2) Outermost layer is sclera
3) The transparent front portion of the sclera is the cornea.
4) The interior part of the eye except the cornea is protected by a
membrane called conjunctiva.
5) Middle layer is choroid.

5. TEACHING LEARNING INTERACTION PUPIL RESPONSE
Introduction
As part of awakening process, teaches conducts can active
discussion with students, Teacher shows a picture of beautiful
garden and asks them what is this? Teacher says V.Good. Is this
picture beautiful? How did you felt that the picture is beautiful?
Can you name the sense organ that helps in seeing? V.Good. so
today we are going to learn more about eye and its structure.
Presentation
Structure of Eye (BBH)
Teacher teaches the structure of eye with the help of a model.
Teacher teaches that the eyeball has three layers. The outermost
layer is the sclera. It imparts firmness to the eyeball. The
transparent front portion of the sclera is the cornea (BB). The
interior part of the choroid behind the cornea there is a circular
dark screen called iris (BB). Pupil is the aperture at the centre of
the iris. It regulates the amount of light entering the eye. The
convex lens (BB)is placed behind the pupil.
Pupil says a garden
Pupil says buds, flowers, trees etc.
Pupil says yes
Pupil says by seeing
Pupil says ‘eye’
Pupil listen carefully

6. Activity 1
Teacher advices students into two groups, teacher calls one
student from each group and asks them to complete the flow
chart given in chart using marker pen.
Peculiarity Function
Teacher then teaches students that retina (BB) is the
innermost layer of the eye where the image is formed. The part of
the retina with greatest vision is called the yellow spot and that
with no vision is called blind spot (BB). There are two chambers
inside the eye. Those between lens and cornea are called aqueous
Pupil divides actively and
completes the flow chat correctly.

7. chamber (BB). It contains a fluid called aqueous humor (BB) which
supplies nutrients and oxygen to the cells of the cornea and the
lens. The chamber between the lens and retina is the vitreous
humor which helps to maintain the shape of the eyeball.
Activity – 2
Teacher divides the students into two groups and gives them
activity sheets. The questions asked are:
1. The part of the retina with greatest vision is called ……………
2. The chamber between the lens and the cornea is called …………
3. The chamber between lens and retina is called ………………..
Teacher then concludes the activity by saying the answers as
yellow spot, aqueous chamber and vitreous chambers.
Activity – 3
Teacher then asks students to divide into two groups and gives
them a question. Why our eye feels blind for some time when we
pass from a dark room to light room.
Teacher then concludes the activity as when the intensity of light
decreases pupil dilates as in case of dark room. But when it enters
the light room the pupil gets contracted. During this transition
Pupil divides into two groups
actively.
Pupil writes the answer correctly.
Pupil actively divides and discusses
the answer.
Pupil listens carefully.

8. time the eyes feels to be blind.
FORMATIVE ASSESSMENT
Review Questions
1. What is the function of Sclera?
2. What is the function of Choroid?
3. Which is the innermost layer of the eye?
