My DD stated categorically that she would not be slicing and dicing any froggies for biology lab, so I searched out a great virtual frog dissection lab.
Frog Lab from biologycorner.com This includes detailed, high school level lab worksheets.
Virtual Frog from the Berkley Lab is mostly drawings, but not a lot of info and does not include a lab.
Virtual Frog Dissection has an audio lecture component that is very detailed. No written lab, but a really good lecture.
AnimalLearn has a list of virtual dissections from cats to grasshoppers to squid. Great resource.
Virtual Fetal Pig from Whitman College is a series of detailed pictures that cover the dissection of a fetal pig and include a short quiz at the end.
