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) perhaps this virtual frog dissection will fill the need (please check the laws in your state for actual requirements).
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 Training Tools for less than $15. The kit includes everything you need including tools, illustrated guide…and frog.
