KS2 Science Quiz: Explore Sight and Sound Wonders

Science Quiz - Eyes and Ears (Questions)

Discover the wonders of sight and sound with this KS2 Science quiz! Let's explore how our eyes and ears, the amazing sense organs, help us see and hear.

Our eyes give us sight, letting us read, write, and catch a ball. Ears help us hear, allowing communication and alerting us to danger. Harry Houdini, the famous entertainer, said, "What the eyes see and the ear hears, the mind believes." But how do these incredible organs work?

Science Quiz - Eyes and Ears (Answers)

What does the eye respond to?

[ ]	Colour
[ ]	Shape
[x]	Light
[ ]	Movement

Although our eyes allow us to see colour, shape and movement, they only respond (react) to light. Try sitting in a dark room before looking at your pupils in a mirror - notice the way your pupils react to changing levels of light

The ear has two main functions - one is to hear but what is the other?

[ ]	To sense changes in the weather
[x]	To sense changes in position
[ ]	To sense changes in temperature
[ ]	To regulate hormones

Being filled with fluid, the ear can detect any movement we make, therefore helping us to balance - the skin detects changes in temperature, while we use several senses together in order to detect changes in the weather

Which of the following protects the eye?

[ ]	The cornea
[ ]	The retina
[ ]	The iris
[x]	The eyelids

The eyelids, as their name suggests, are protective lids, or covers, for the eyes

Sound waves cause which three small bones in the ear to vibrate?

[x]	Ossicles
[ ]	Follicles
[ ]	Ampullae
[ ]	Cochlea

The ossicles are the smallest bones in the human body

Which is the coloured part of the eye?

[ ]	The cornea
[ ]	The pupil
[x]	The iris
[ ]	The retina

The colour of the iris is what we mean when we say someone has brown or blue or green eyes. Although it looks black, the pupil has no colour, because it is a hole

Sound waves travel down the ear canal before hitting what?

[ ]	The pinna
[ ]	The inner ear
[ ]	The ear lobes
[x]	The ear drum

The ear drum vibrates when it is hit by sound waves - these vibrations then cause the ossicles to vibrate

The lens focuses images onto what at the back of the eye?

[x]	The retina
[ ]	The pupil
[ ]	Eyelashes
[ ]	The cornea

The retina is a group of cells that are sensitive to light. They send messages along the optic nerve to the brain, which forms an image

Which nerve takes signals from the ear to the brain?

[ ]	Spinal nerve
[ ]	Optic nerve
[x]	Auditory nerve
[ ]	Olfactory nerve

Auditory means 'related to hearing'

Which nerve takes signals from the eye to the brain?

[ ]	Spinal nerve
[x]	Optic nerve
[ ]	Auditory nerve
[ ]	Olfactory nerve

Optic means 'related to vision'
