Using tools Please be careful with dissecting scissors. They can be sharp, you do not want to cut yourself or others. Please follow all directions
Cutting into a frog Pull both arms hard (pop them out of the sockets) this gets the arms out of the way. We are not using pins Cut horizontally at the bottom of the stomach Cut vertically down the center of the chest (cut the top layer of skin) Cut vertically down the center of the chest again. Cut through ribcage (you may need to apply pressure) Pull skin back to expose organs.
Exploratory Take a look at the organs Use the mat to try to identify the different organs Try and discuss the functions of different organs If you choose you may open other parts of the frog (this is on you I do not help)
