Miss Frizzle and her class are off and running...literally...as their latest field trip takes them to the electric company, where they are soon traveling through the wires as current and powering everything from vacuum cleaners to toasters to saws. This newest addition to the Magic School Bus series features the usual frenetic combination of lively, informative text and illustrations and diagrams that are jumping with energy, information, and, of course, humor. Miss Frizzle and her class are real live wires. (Ages 5-7)
