Check out the Biology & Paleontology Q&A blog

Why do humans have noses and great apes don't? What is a pseudoscorpion? Did Diplodocus drag its tail on the ground? These questions and more are answered in the Biology & Paleontology Q's & A's blog. This blog is run specifically for answering the questions of schoolchildren (although I'm sure they'd answer questions from curious adults). They offer a wealth of experts is many fields of biology, paleontology (duh), ecology, evolutionary biology (my favorite!), dinosaurs, elephant locomotion, the list goes on... Very cool resource for young scientists!
