Frog Dissection: It's a ribbeting day!

Who knew 10 years ago I would be standing in a formaldehyde-smelling room taking out frog tongues? SURPRISE! Yesterday and today, we dissected the external parts of the frog. On Monday, they made observations about the dorsal (new vocab word) and ventral (new vocab word) sides of the frog. Today, we dissected and learned about the anatomy of a frog's mouth. But, we are getting to the heart of the frog dissection tomorrow and the rest of the week. I recently stumbled across an AMAZING website that guides you through the internal systems of the frog. One reason that I love it so much is because it is very difficult for kids to see what I am talking about when I point to one tiny aspect on one tiny frog. We are using northern leopard frogs by the way. This website takes you step-by-step through the process of each system of the frog.  Anyways, I thought I would share my little bit of heaven website:

This website is wonderful! Do you dissect? If so, what do you dissect? I have heard that the bullfrogs are SO much better than the leopard frog to dissect, but I don't know if it is worth the $$.. What are your thoughts?
