We did a worm, frog, pig, turtle, and a clam. In college we dissected a cow’s eyeball. I hated every minute of it, but I think the person was on point with stating sometimes we have to learn to do things that we do not like to do.
I remember getting a cow's eye from the local butcher and dissecting it for a classroom demonstration when I was in fifth grade. Used a single-edged razor blade and a bunch of straight pins. It went pretty well, if I do say so.
The "science" department was cheating and defrauding the students.
