While we're talking about Science Blogs, let me point you to their donation drive, in association with Donors Choose. Science Blogs blogger Janet Stemwedel has pointers here to all the Science Blogs donation challenges, and I'd like to point you all to that of my colleague Mark Chu-Carroll, in particular, over here.
Go take a moment and read about it. Then look over the proposals, and please fund one, fully or partially. They're all small things we can do to help kids learn.
