Here is a very cool site passed on by Vancouver author/illustrator Cynthia Nugent.
It's a new blog created by three PHD students called Science in Seconds and it's your go to place for snippets of science that are understandable but not dumbed down. It isn't a site aimed at kids, but if you write non-fiction for kids, or if your fiction is touching on sciencey (I know that isn't a word but it should be) themes, this is a great site to check out. Their motto is "Know Everything," which is a pretty cool. They've already attracted thousands of hits each week (I'm so jealous).
Thanks for the heads up Cynthia.
