Don’t know if you saw this already, but here is a link to the ALA’s Association for Library Services to Children’s Great Web Sites for Kids page:
Literature, Science, Math, Art, History, Animals, …. Plus sites for Parents & Teachers.
And check out the featured site for January, done by author Kenneth Libbrecht - Snowflakes and Snow Crystals.
