Dissecting (again)

Forget what I said last time! This science class was better by far! We were dissecting a lambs lungs, heart and windpipe. 
We started by removing the heart.
Then we slit the windpipe open,
Then we cut the heart open.
And then we discovered that one of our lungs was split, so we cut off the bottom
Then we cut off the other lung
And then we cut that open along one side so that we could look at that end. By then my iPod was away, so I don't have any photos of that bit. But this one was way more fun then the last. Any pics that have hands with no gloves in them, are me; I didn't feel like wearing gloves.

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.
