I took Biology in grades 7, 8, 10, 11, and 12, but never dissected a cow eyeball or did a frog dissection. The school didn’t think it was necessary for our education to cut in dead animals, and I agree. Never in my life have I ever thought “Oh, if only we had done the frog lab in school!”
Since I’ve never seen a frog being cut open I can’t say how realistic this is, but it looks pretty cool. CraftyHedgehog makes these knitted frog dissection displays, and also sells patterns to try it yourself.
