Well, you knew it had to happen eventually. Your high school student needs to dissect a frog. If you prefer to avoid the mess (and smell, among other things) perhaps this virtual frog dissection will fill the need.
Even if you plan to dissect an actual frog, the virtual dissection provides a good review. If you are into notebooking, you can include an experiment worksheet.
Update: Flash is required, though there are apps and browser plugins that will still let you run it.
