Gr 4-6–A clone of Ms. Frizzle from Scholastic’s “The Magic School Bus” series introduces four students and a pair of aliens to important organs. The graphic-novel format doesn’t disguise the books’ didactic passages and awkward dialogue, and the all-caps font sometimes makes reading challenging. However, the books give an accurate inside look at the organs and their roles, placement, and operation, as well as related organs and systems. The illustrations incorporate scientific images and labeled body parts. Final panels cover safety and health tips, and a closing diagram of the featured organ’s main features provides a quick review. The format of these books will draw readers.
