Corrected sentence:

Hearing starts when a sound wave goes into the outer ear and makes the eardrum vibrate. The eardrum moves three tiny bones, and they send the sound into a snail-shaped part called the cochlea. Nerves then send messages to the brain so it can tell what the sound is.

Step-by-step for a 6-year-old:

  1. Sound travels through the air like tiny waves.
  2. The outer ear catches the sound and sends it to the eardrum.
  3. The eardrum vibrates and moves three tiny bones inside the ear.
  4. Those bones push the sound into a snail-shaped tube called the cochlea.
  5. The cochlea turns the sounds into tiny messages.
  6. Nerves carry those messages to the brain. The brain figures out the sound.

Why I changed it:

  • Changed "HEARING" to "Hearing" for normal capitalization.
  • Used "goes into" and "makes the eardrum vibrate" to be clearer than "gets into" and "hits."
  • Split into shorter sentences so each idea is easy to understand.
