Rio Grande (rē`  grän`dĭ), city (1991 pop. , and Mississippi have played important roles
in American history, explains Castaldo, a former environmental educator.
She starts, however, with the basics, instructing her young readers
about water evaporation evaporation, change of a liquid into vapor at any temperature below its boiling point. For example, water, when placed in a shallow open container exposed to air, gradually disappears, evaporating at a rate that depends on the amount of surface exposed, the humidity , precipitation, and flow. The first project in
the book is to "create your own river" out of rocks, sand, and
a pitcher of water. Interspersed with activities are descriptions of at
least 25 North American rivers. For most of these, a simple table lists
length, watershed size, major tributaries, and cities served. River
animals are a focus of the book, which includes features on beavers, the
American alligator alligator, large aquatic reptile of the genus Alligator, in the same order as the crocodile. There are two species—a large type found in the S United States and a small type found in E China. Alligators differ from crocodiles in several ways. , and the many species of birds that rivers are home
to. Castaldo provides instructions for 30 games, activities, and
experiments that relate to rivers, such as how to pan for gold, make a
rain gauge, and hunt for fossils. Chicago Review Press, 2006, 144 p.,
