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.
By the way, if you prefer the real thing, you can purchase a frog dissection kit from Home Science Tools for less than $20 (we have been very pleased with their dissection kits). The frog dissection kit includes everything you need including tools, illustrated guide, …and frog.
