Gr 2-4-In these two titles, the subjects are divided into 22 double-page descriptions, with the left-hand page offering factual information and a related art project appearing on the right. For instance, in Space, the topics include Saturn's rings, aliens, black holes, etc. Structures looks at tents, skyscrapers, and pyramids as well as stained glass, highways, glassblowing, plastics, etc. While many of the projects are educational, several of them are just for fun. Children will enjoy the interconnected facts and activities, and busy teachers trying to extend their lessons with meaningful art activities will also appreciate them.-Cathie Reed, The Montessori School, Lutherville, MD Copyright 2002 Cahners Business Information.
