  • 4. How does the ear work?
    • The ear works very quick so messages can be sent to out brain.
      • First the sound vibration enters the ear. Our ears are slightly curved so that the sound gets caught.
      • The vibration hits the ear drum which the vibrations on to the hammer.
      • The hammer passes it on to the anvil.
      • The sound is then carried on to the stirrup.
      • Then finally the sound reaches the cochlea.
      • Hair in side the cochlea become electric and this sends an electrical message to the brain.

  • 5. Parts of the Ear
    • Ear Drum- A thin piece of skin that separates the outer ear from the middle ear.
    • Hammer - It is a tiny bone next to the ear drum and it vibrates by the ear drum tapping it.
    • Anvil - Another small bone next to the Hammer . It
    • vibrates when the hammer knocks it.
    • Stirrup- A part of the ear next to the Anvil that gives the noise to the cochlea.

  • 7. Sounds and Vibrations
    • Sounds travel though molecules.
    • This works like marbles. The first one will push the next one then that one will push the third one and so on.
    • Speed of light is faster than speed of sound because of the distance away the noise came from.
    • Depending on the surface the noise hits depends how strong it will reflex and where it will reflex.
    • The temperature affects how fast sounds travels.
