Hearing
  1.  Sound waves make your eardrum vibrate. 
  2. The movement of the eardrum makes the first small ear bone vibrate. 
  3. The three small ear bones make the vibrations stronger. 
  4. These vibrations create waves in the fluid of the cochlea, a part of your inner ear. 
  5. The wave movements in the fluid stimulate sensory cells in the cochlea, which send signals. 
  6. These signals travel through a nerve to your brain, where the sound is understood.

Put in the correct order
  1.  The brain receives and processes the impulses to create an image. Only then do you see the stop sign
  2. The sensory cells change the light signals into impulses.
  3. The light hits special light-sensitive cells in your eye (on your retina).
  4. The impulses are sent to the optic nerve.
  5. The impulses go to your brain.
