The indomitable Ms. Frizzle is back for a lesson in electricity in this entertaining entry in the Magic School Bus series. The class begins with books, videos, experiments, and research reports; Ms. Frizzle, wearing a dress of geometric shapes, explains atoms and electrons, and, during an electrical storm, gets the students and her niece, Dottie, into the school bus to find out what's behind a power blackout. At a power plant, they learn how electricity is generated and how it travels. As in the other books in the series, this one doesn't cover everything, but it will stimulate interest; plenty of information is packed into the pages, and repeat readings are mandatory.
