Grade 3-4-Fine introductory titles. In the first book, the easy-to-read text offers clear explanations about the ways fossils are formed and information on reading the record they leave behind. It also includes brief descriptions of a paleontologist's work and how museum exhibits are created. In Rocks, the basic formations (igneous, sedimentary, and metamorphic) are introduced. A "Did You Know?" section provides some additional facts. In both titles, not all scientific words are given phonetic pronunciations. Well-selected, beautifully reproduced photographs and computer graphics illustrate these volumes.Kathryn Kosiorek, Cuyahoga County Public Library, Brooklyn, OH Copyright 2001 Reed Business Information, Inc.
