What about in depth studies of biomes? He could pick a biome and then through books from the library, school, and also internet websites just study the heck out of them.
Fun part of studying biomes are live webcams...thinking Monterey Bay has cool live cams and some of the African grassland santuaries have live web cams...and along with these web cams are great web pages with tons of information.
Another way would be studying just one particular animal at a time. I happen to follow Lily the Black Bear and the North American Bear Center and the WildLife Research Institute for no other reason that it caught my attention when there was a den cam of Lily giving birth to her cub Hope and that the researchers had a ton of information about bears that I didn't know before. I someday hope to go to Ely, Minnesota and visit the NABC.
I happen to have my very own list of animals that I identify with and crave to learn more about...Sandhill Cranes, Pelicans, the heron/egret family, Bald Eagles, bears, whale/dolphin family, and crazy looking fish (you know the real ugly looking ones or the ones that can do amazing things).
