squirms Ay, I can never do dissections. It’s not that they gross me out, I just cannot make myself do them; I think it’s because I knew it was living at one point. Heck, I can’t even cut open a dead worm! That aside, quite the biology class. One tiny suggestion I’d make: try to do a bit more “showing,” you’re doing some, but not quite enough. Other than that, I’m most interested, being a self-declared geek myself.
In grade 8 and 9 science classes, biology was always my least favourite class. It always amazed my that, in both grades, not one person ever puked during a dissection (though I think I came close doing frogs). :-)
