Nature Study Resources

Does anyone have any great websites, handbooks, sources of great material etc. for nature study? We go outside a ton and do all the obvious things but I would like to add some nature study topics from places other than our own. We are going to be doing Road Trip USA next year and I am trying to combine a bit more nature study along with it by focusing on something different from each of the regions. I would love to locate either sources of great pictures/videos or sources of actual hands on material for things we don’t have here (which is Alaska.) Any input or suggestions would be great. Thanks so much!

Nature Watch has a lot of cool stuff!
