Since I don't think you're going to find any published resources on what you're looking for I would ask the teacher if acceptable resources would be breeders of each respective species. If yes, then I would post a thread here asking for information on the snake's weight, plus the frequency and size rodents consumed. Hopefully you'll find someone to provide information for you.

I see you have 3.4 ball pythons already, see if you can use your own records (weight and feeding) as a resource.

Good Luck
