Gr 2-5-These series entries present science concepts through a series of experiments. The science is accurate, but the illustrations are distracting. In Bangs, unattractive cartoon-styled characters (a big-mouthed, skinny-legged woman and a wisecracking robot) introduce sound and how it works. In Squirts, the duo presents the physics behind water pressure. Home use rather than school is implied and some of the projects could create quite a mess-squirting water out of the mouth, making a squirt gun, a balloon water shooter-and would best be done in the backyard. Others could get very noisy. The materials needed for the experiments are readily available in the average home and the directions are clearly stated and illustrated. These titles lack the charm and effectiveness of Joanna Cole's "Magic School Bus" series (Scholastic). The Frizz still reigns!-Eunice Weech, M. L.
