Dissecting cows eyes

Science class yesterday was the best yet! I'd been looking forward to it all week. We dissected cows eyes! (Quick warning, if you tend to feel a bit queasy around these things then I suggest that you leave, as photos will be included). Our science teacher explained step by step of what we had to do, starting with cutting all of the excess off of the outside.
Once that was finished, we had to cut it down the middle so that we could get inside it.
Once we had succeeded in doing that, we then had to find the lens. A lot of gooey stuff came out.
Eventually we managed to find the lens in all that mess
After that, we had to try and find the black bit with the pupil hole in the middle.
Though, ours kind of broke.
After that we had to turn the eye inside out to find the retina. 
Eventually we managed it.
After that, to the disgust of the boys in the group beside us, I took off my gloves and held the eye, because I wanted to know what it felt like.
Honestly, it felt a little weird. Well that was the end of our science class. It was heaps of fun, and I hope we get to do it again sometime.

  2. Omgosh I used to love teaching eye dissection but what on earth where you using the scalpel with somebody's hand underneath for? Please never do that again, you will cut someone badly. You did a great job of blogging this process, well done!
    What did you think of the feel of the jelly inside? Did you get to see the optic nerve out the back of the eye?

  3. Gee, well done, especially to hold it! Funny that the boys were a bit squeamish about doing this!
    I know my students always found this dissection a good experience
