The NOAA Teacher at Sea Program sends teachers out to sea on Coast Guard ships. They have published several children's books about the teachers' adventures. The books include basic information about the ships, oceanography, climate, and the environment. Each book has a glossary and is illustrated with beautiful pictures. You can download a pdf copy to use right now and you can also request an original copy of each book from NOAA by e-mail.
