This is a “virtual lab” where students create a three-layered diagram (external, internal and key) to a generalized bony fish.  Feel free to provide whatever classroom resources you want, mine use a plastimount fish model and I have a diagram in the room that requires them to generalize the layout.  Or, send students to this page for the key.
