This is a really cool site, whether you want to visit a national park in the great US of A, or if you need to do a report or some research. You can even visit the national parks online and get great info on why you might want to visit one. There is even a page to check out volunteer opportunities in different parks around the country.
I highly recommend the Learn NPS section. It is chock-full of information for both teachers and students and has some very interesting ways to learn about America. Their feature this month is Thomas Edison (whose birthday was February 11th). This site is fabulous, I hope you all check it out.
