Ears
,→Key Stage 3
: The ears of different animals can hear different sounds. Some animals can hear sounds too high pitched for us to hear and some can hear sounds too low pitched for us to hear.
There are several parts of the ear you should know:
*[[Pinna]] - The shaped [[cartilage]] collects the sound.*[[Ear Cannal]] - The tube leading to the [[Ear Drum|ear drum]].*[[Ear Drum]] - This vibrates [[vibrate]]s like a drum skin when sound hits it.*[[Ear BonesOssicles]] - Three tiny bones [[bone]]s that pass the [[Vibrate|vibration ]] to the [[cochlea]]. *[[Cochlea]] - A spiral tube with a [[liquid ]] inside it and tiny hairs attached to [[nerve ]] cells.*[[Eustachian Tube]] - A tube used to keep the [[pressure]] the same both sides of the [[Ear Drum|ear drum]] to stop it bursting.*[[Auditory Nerve]] - The [[nerve]] connecting the '''ear''' to the [[brain]]. {| class="wikitable"|-|[[File:EarDiagram.png|center|400px]]|-| style="height:20px; width:400px; text-align:center;" |A [[diagram]] of the '''ear'''.|}
