TARGET>4th Grade text book on Explorers

[Rita Hennessey <RitaInCT@AOL.COM>]

Hello, all you helpful netters!

Does anyone out there know of a great (or even good) text book for 4th grade
that deals with explorers?  The scope can be either 14th-17th centuries, or
longer (covering not only the Age of Exploration, but underwater exploration
a la Jacques Cousteau and space exploration, etc).
