This week’s Website of the Week is Ask-A-Scientist, operated by the Division of Educational Programs at Argonne National Laboratory. This educational outreach program – now in its 17th year! -- is designed for students and teachers in grades K-12. Have a question about science that you just can’t find an answer to anywhere else on the web? This is a good place to post it. Previous answers are indexed under categories such as astronomy, materials science, veterinary, and weather. Want to learn about Cow Magnets? Why Boiled Eggs Turn Solid? Why people sometimes have Red Eyes in Photographs? These answers, and more, are waiting for you in the Ask-A-Scientist questions and answers archive.
