Key Stage 1

Meaning

 
A human ear lobe

An ear is the part of the body we use to hear sound.

Singular Noun: Ear
Plural Noun: Ears

About Ears

The ear lobe is the shaped part of an ear that we can see.
You do not need an ear lobe to hear. Most of the important parts of the ear are deep inside the hole.
If your ear does not work and you cannot hear, then you are deaf.
Ears should not be cleaned with cotton bud as it can cause an 'ear infection'.

Examples

 
 
The ear of a reptile. A monkey's ear.
 
 
The ear on a dog. An elephant's ear.

Key Stage 2

Meaning

An ear is the part of the body we use to hear sound.

Singular Noun: Ear
Plural Noun: Ears

About Ears

The ear lobe is the shaped part of an ear that we can see.
You do not need an ear lobe to hear. Most of the important parts of the ear are deep inside the hole.
If your ear does not work and you cannot hear, then you are deaf.
Ears should not be cleaned with cotton bud as it can cause an 'ear infection'.

Examples

 
 
The ear of a reptile. A monkey's ear.
 
 
The ear on a dog. An elephant's ear.

Key Stage 3

Meaning

 
A cross section of a human ear.

The ear is a sensory organ that can detect sound.

About Ears

Most animals have two ears.
Ears can be damaged by listening to loud sounds too often.
The ears of different animals can hear different sounds. Some animals can hear sounds too high pitched for us to hear and some can hear sounds too low pitched for us to hear.

There are several parts of the ear you should know:

 
A diagram of the ear.

Key Stage 4

Meaning

The ear is a sensory organ that can detect sound.

About Ears

Ears can only detect a certain range of frequencies of sound which depends on the size of the ear drum.
Human ears can only detect frequencies of sound above 20Hz and below 20,000Hz. Sound below 20Hz is referred to as infrasound. Sound above 20,000Hz is referred to as ultrasound.
Different animals can hear different frequencies of sounds. Some animals can hear infrasound and some can hear ultrasound.

There are several parts of the ear you should know:

 
A diagram of the ear.
