Sally M. Walker, “Shipwreck Search: Discovery of the H. L. Hunley” 
1 pdf

Walker earned a Sibert Award for Secrets of a Civil War Submarine (2005). In this entry in the On My Own Science series, she presents information about the same historical mystery for a younger audience. Relating the story in loose sections rather than formal chapters, Walker takes readers briskly through the science of finding and raising the H.L. Hunley, a downed Civil War sub. Then she explains how scientists discover how the sub operated, why it might have sunk, and who was on board. There is a lot of information here for readers new to this topic, with technical terms such as magnetometer and truss included. The exciting telling will keep the audience interested. Watercolor illustrations show two laboratories, above and below the water"s surface. A substantive afterword, a glossary, a time line, and a bibliography round out the book.
