cow eyes!!!

i didn't blog when we did the cow eyes because i had the flu and was out on the Wednesday. The cow eye dissection was very important because that showed us how the eye works and how it lets the light pass through the eye causing us to see This is very important because we should know how our eyes use refraction to let us see and how the principals of light are applied to how we see.
We got to see some of the following parts in the cow's eye:
  1. Retina
  2. Optic nerve
  3. lens
  4. Iris
  5. pupil
  6. Cornea
  7. Optic disk


It was pretty cool.
what i learnt was that the light would enter the eye and refract in the Aqueos Humerous and go through the pupil and refract in the lens and goes to the retina and casts the picture of what the light bounced off of and thats how we see.
