Depending on where you are, spring is either wrapping up or just around the bend. From the sounds of spring peepers peeping to birds chirping, this is definitely the season of re-birth. Check out this handful of sites that look at some of the signs of spring. The first site (1), from naturesound.com, allows you to hear the chorus of a truly spring sound: spring peepers. Next, from Education World, is a good collection of lesson plans for any teachers out there hoping to bring some spring fever into the classroom, or at least try to harness it(2). The Chicago Tribune (3)has the spirit with this feature on the signs of spring in the third site. The fourth site (4), from the Illinois State Museum, will help those out there considering putting in their own prairie garden this spring -- a perfect time to plant. The fifth site (5) is from eNature.com and offers a great look at the spring migration. Lastly is a show from NPR on spring bugs (4).
