Question types: The eye and the ear

Rule: Sense organs

Eye: the cornea and lens bend light, the iris changes the size of the pupil, the image forms on the retina.

Ear: the eardrum vibrates, three tiny bones pass the vibrations on, the cochlea turns them into nerve signals.

Example: The semicircular canals in the inner ear help you keep your balance.

Watch out: The pupil is not the coloured part of the eye: that is the iris; the pupil is the black hole in the middle.

Sample questions

  1. Question 1 Easy

    What does this part of the eye or ear do? Match each item (1–3) with the right option (A–D).

    1. ear bones (hammer, anvil, stirrup)
    2. eardrum
    3. cochlea
    • A) pass the vibrations on to the inner ear
    • B) contains the hearing cells
    • C) vibrates when sound reaches it
    • D) bends light and focuses the image
    Show the solution
    Answer:
    1. ear bones (hammer, anvil, stirrup) → A) pass the vibrations on to the inner ear
    2. eardrum → C) vibrates when sound reaches it
    3. cochlea → B) contains the hearing cells

    How it works: ear bones (hammer, anvil, stirrup) – pass the vibrations on to the inner ear; eardrum – vibrates when sound reaches it; cochlea – contains the hearing cells

  2. Question 2 Normal

    What does this part of the eye or ear do? Match each item (1–4) with the right option (A–E).

    1. semicircular canals
    2. cochlea
    3. iris
    4. optic nerve
    • A) contains the hearing cells
    • B) contains light-sensitive cells (rods and cones)
    • C) gives the eye its colour and changes the size of the pupil
    • D) carries signals from the eye to the brain
    • E) sense balance
    Show the solution
    Answer:
    1. semicircular canals → E) sense balance
    2. cochlea → A) contains the hearing cells
    3. iris → C) gives the eye its colour and changes the size of the pupil
    4. optic nerve → D) carries signals from the eye to the brain

    How it works: semicircular canals – sense balance; cochlea – contains the hearing cells; iris – gives the eye its colour and changes the size of the pupil; optic nerve – carries signals from the eye to the brain

  3. Question 3 Hard

    What does this part of the eye or ear do? Match each item (1–5) with the right option (A–F).

    1. lens
    2. cochlea
    3. optic nerve
    4. eardrum
    5. retina
    • A) carries signals from the eye to the brain
    • B) gives the eye its colour and changes the size of the pupil
    • C) contains the hearing cells
    • D) bends light and focuses the image
    • E) contains light-sensitive cells (rods and cones)
    • F) vibrates when sound reaches it
    Show the solution
    Answer:
    1. lens → D) bends light and focuses the image
    2. cochlea → C) contains the hearing cells
    3. optic nerve → A) carries signals from the eye to the brain
    4. eardrum → F) vibrates when sound reaches it
    5. retina → E) contains light-sensitive cells (rods and cones)

    How it works: lens – bends light and focuses the image; cochlea – contains the hearing cells; optic nerve – carries signals from the eye to the brain; eardrum – vibrates when sound reaches it; retina – contains light-sensitive cells (rods and cones)
