The document provides details of an innovative biology lesson plan about the ear. It includes the learning objectives to develop knowledge of ear structure and function through various teaching methods. Key points are to understand that the ear has external, middle, and inner sections; sound is transmitted through the pinna, ear canal, eardrum, ossicles, and oval window; and the cochlea contains receptors that transmit signals through the auditory nerve. Assessment includes questions, group activities, and diagrams to ensure students comprehend the major structures and functions of the ear.

CURRICULAR STATEMENT
Develop factual, conceptual, procedural, metacognitive knowledge, process skills
and attitude on ear through lecture method, demonstration, group discussion and evaluation by questioning, participating in
group work and discussion.
CONTENT ANALYSIS
NEW TERMS: pinna, ear drum or tympanum, ear canal, ear ossicles, Eustachian tube, cochlea, oval window, perilymph,
endolymph, organ of corti, auditory centre
FACTS:
 Pinna directs the sound waves towards the ear canal.
 Ear canal directs sound waves to the ear drum. Small hairs and ear wax seen in this area prevent dust and pathogens.

2.  Ear drum or tympanum is the membrane at the inner most end of the ear canal. Vibrates in accordance with sound
waves.
 Ear ossicles directs the vibrations that occurin the ear drum towards the oval window. It consists ofmalleus, incus, and
stapes.
 Cochlea is the part with three fluid filled sacs. Auditory receptors are situated in this part. It has a shell of snail like
appearance.
 The middle chamber of cochlea is filled with a fluid called endolymph and other two with perilymph.
 Oval window vibrates in accordance with the vibration of stapes.
 Eustachian tube connects the middle ear with pharynx. It regulates the pressure in the middle ear.
 Vibration of the oval window causes vibration in the perilymph.
 Organ of corti is located in the middle chamber of cochlea.
 Impulses thus formed reach the auditory centre of the brain through the auditory nerve.
 The semicircular canals and vestibule that are parts of the inner ear help to maintain the equilibrium ofthe body. These
parts are filled with endolymph
CONCEPTS
MINOR CONCEPTS
 External ear constitute pinna, ear canal, ear drum.
 Middle ear consists of ear ossicles and Eustachian tube.
 Internal ear consists of oval window, cochlea, semicircular canals, vestibule and auditory nerve.
MAJOR CONCEPTS
 Ear is the sense organ that aids in hearing. It consists of external, middle and internal ear.

3. LEARNING OUTCOMES IN TERMS OF SPECIFICATIONS
Enable the pupil to develop
1) Factual knowledge on ear through:
a) Recalling the new terms like pinna, ear drum, ear canal, ear ossicles, Eustachian tube, cochlea, oval window, perilymph,
endolymph, organ or corti, auditory nerve.
b) Explaining about ear, its parts and functions.
2) Conceptual knowledge on ear, its parts and functions through:
a) Explaining about ear, its parts and functions.
3) Procedural knowledge on ear and its functions through:
a) Explaining about ear, its parts and functions.
4) Metacognitive knowledge on ear and its functions through
a) Recognizing about ear, its parts and functions.
b) Describing about ear, its parts and functions.
5) Different process skills through:
a) Observing different parts of ear and its functions.
b) Identifying different parts of ear.
c) Communicating through presenting group work.
6) Scientific attitude towards the study of ear, its parts and functions
PREREQUISITES

CLASS ROOM INTERACTION PROCEDURE PUPIL RESPONSES
INTRODUCTION
Teacher makes a rapport with students by asking questions
related to contextual situation .Then teacher asks following
Questions for checking previous knowledge
1) What are sense organs?
2) Can you name any sense organ?
3) Which is the sense organ which helps in hearing?

5. Teacher says “so today we are going to study about ear and its
Parts along with its function”
PRESENTATION
ACTIVITY I
Teacher shows a CD depicting ear and its parts. Teacher asks
Students to observe the various parts of ear.
BLACKBOARD
 Pinna
 Ear canal
 Tympanum
 Eustachiantube
 Ear ossicles- malleus, incus, stapes
 Oval window
 Cochlea
 Auditory nerve
 Semi circular canals

6. ACTIVITY II
The teacher shows a chart explaining parts of ear and
their functions. Later she explains about it.
Consolidation
Ear is senseorgan which aids hearing and it
has external ear, middle ear and internal ear.
EAR
EXTERNAL EAR
 Pinna- directs the sound waves towards the ear canal
 Ear canal – directs sound waves to ear drum. Small
hairs and ear wax prevent dustand pathogens

7.  Ear drum /tympanum – membrane at the
innermost end of the ear canal. Vibrate the
accordancewith sound waves.
MIDDLE EAR
 Ear ossicles– direct the vibrations that occurin ear
drum towards the oval window. It consists of incus,
malleus, and stapes.
 Oval window- vibrates in accordancewith the
vibration of stapes.
 Eustachiantube – Connects middle ear with
pharynx. Regulates pressure in the middle ear.
INTERNALEAR
 Cochlea – It has three fluid filled sacs. Middle
chamber filled with endolymph and others with
perilymph. Auditory receptors seen in the organ of
corti in middle chamber.
 Semicircularcanals and vestibule – It is the part
of inner ear help to maintain the equilibrium of the
body. These parts contain endolymph.
 Auditory nerve – impulses are carried to auditory
nerve.

8. Teacher asks questions,
1. Which are the parts of internal ear?
2. What is the function of Eustachian tube?
3. What is organ of corti?
