Frog during freshman year, and a pig sophomore.
Edit: I didn't do it. My class did. I did not partake in the dissection 'cause I felt like I wouldn't learn anything from it. Based on the way my classmates behaved, they didn't seem to learn anything, whatsoever.
I'm not sure I've ever even been a student of a school that did this. But it strikes me as a both an act of cruelty to animals, and a blatant display of the sheer masturbatory pointlessness of the educational system. (not to mention a waste of tax dollars) Kids presumably go there to prepare for the real world, but instead we have them cut up frogs.
A few frogs, a worm, some small shark (that was in high school, can't remember what its actual name was) and something else, but I can't remember what it was. Basically, breaking it down it was:
High School: Worm, Frog, small shark, I believe it was some sort of feline (not something you'd keep as a pet, but it was pretty small) and maybe one other thing.
College: One frog.
Frog and Owl vomit whatever that's called. That's all I remember anyway.
But i chose everything just in case. Multiple choice is the worst.
Edit: Btw, that smell is formaldehyde (I think it is). The dead animal you dissect doesn't have any smell as it's been disinfected and stuff.
Frog in 5th grade, worm and pig in 8th, and a cat during senior year of high school. I thought they were all pretty neat experiences. I don't understand the folks who claim it is cruelty to animals. I'm pretty sure most of the animals that students dissect are the byproducts of something else. The cat I dissected was a stray that was put down as part of some effort to clean up a big city. The pig fetuses come from rendering plants, I think. I guess I don't know about the frogs. Expired stock from French restaurants?
Once we had the choice between like 4 animals. I went with a fish with another person. It still smelled horrible.
Second time it was a pig. It was pretty funny. Three Muslims and a Jew cutting up a pig. I let my 3 partners cut the pig while I concentrated on identifying more difficult to notice parts. Got a perfect mark.
Nothing living, just the preserves Sheeps eye.
I'd say that I'd be surprised if anyone was required to dissect something living, but then my first dissection assignment in high school Biology was a worm that we had to kill with chemicals before we could actually start the slicing.
I have seen a worm shit itself in pain. It's not a pleasant sight.
@hailinel: I think it might be, or at least used to be common for schools to use some kind of paralyzing agent on frogs so you could cut open the chest cavity and see the lungs in action. I wouldn't be surprised if they stopped doing that though, it does seem quite cruel, even if it is educational.
