The Sense of Sight
We use our sense of sight to see everything around us. The sense of sight allows us to identify size, shape, colour and
movement.
The Cornea is a transparent covering that protects the eye.
The Iris is a muscle that controls the size of the pupil and the amount of light that enters your eyes.
When you look an object, light bounces off the object into your pupil. The lens focuses this light and makes an image of the object on the retina.
The retina is connected to the optic nerve. The optic nerve carries the picture from the pupil to the brain.
Can you believe your eyes?
Interesting fact
Seeing is such a big part of everyday life that it requires about half of the brain to get involved.

The Sense of Hearing
We use our ears to hear sounds and noises. Sounds can be very nice like music or birds chirping. Noises are loud and
unpleasant.
When we hear something, sounds enter the outer ear and travel to the eardrum.
The three small bones, the hammer, the anvil and the stirrup make sounds louder.
The hammer, stirrup and anvil pass the vibration to the cochlea which is connected to the auditory nerve.
The auditory nerve carries the sounds to the brain.
Interesting fact
The smallest bone in the body is located in the ear.

The Sense of Taste
We use our sense of taste to taste things. We
use our tongue to identify different flavours.
Taste Buds
We detect taste with taste receptor cells. There are lots of receptor cells in the
taste buds. The taste buds are in our tongue.
There are four primary taste sensations: salty, sour, sweet and bitter.
Interesting Fact
In general girls have more tastebuds than boys.
The Sense of Smell
We use our nose to smell things and to taste food. Our nose can detect more than 1000 different
smells.
Smell goes into the nose through two holes called nostrils.
The nasal cavity and olfactory nerve are behind the nostrils.
The olfactory nerve carries the smell to the brain.
Interesting Fact
Taste is about 75% smell.
The Sense of Touch
We feel things with our sense of touch. Our skin is the organ of the sense of touch. We use our touch to feel
textures and temperatures. We use our sense of touch to feel if something is smooth, rough, hot or cold.
Nerve Endings
Nerve sensors in our skin identify the texture and
temperature of objects. This information travels through our nerves to the brain.
Interesting Fact
You skin is the biggest organ your body has.
