But if your in the jungle and it happens to be in the rainforest there just might be a good reason to still have your book of tree species or bird species handy (until apple comes out with the waterproof touch). But until then there are some great sources to look into. The Institute National of Bio-Diversity where I did some of my studies in Costa Rica has quite the collection of books that all go to a great cause. If your interested in these books they all come in English and Spanish and you can click here to take a look at the many different books they have.
Again these are amazing books from studies done in the field and proceeds going back into the field of study. I feel these would be great class room books and they have different books for all ages. If you are ever visiting Costa Rica Inbio Park is also a park worth visiting with a class. It is a small park in the town of Heredia and nothing like getting out into the jungles of Costa Rica but again if you have the time its money going to a good cause.
