"UCSB ScienceLine is an innovative 'Ask a Scientist' program where students and teachers primarily from our local K-12 schools can submit science and engineering questions. ... The scientists usually send their responses back within one week. All questions and answers are posted in our archive." Archives are searchable, or browsable by topic such as astronomy, physics, and geology. Sponsored by the National Science Foundation and the University of California, Santa Barbara (UCSB).
