Rosalind Echols, a physics teacher at the Philadelphia-based Science Leadership Academy, took part in the Teacher at Sea program sponsored by the National Oceanic and Atmospheric Administration (NOAA). In July 2013, she spent 18 days aboard ship Rainier. While on the ship, she mapped the bottom of the ocean and measured the temperature and salinity of the ocean. The students in Echols’ four fall 2013 physics classes will have the chance to work with the data she helped to collect.
