As with all "Magic School Bus" books, this one is clever, educational, and funny. Students will be engaged when reading. The school bus shrinks down and enters Arnold's body. The class explores the digestive system, circulatory system, and other systems of the body. I would use this book to introduce (or re-introduce) the human body systems and their functions. For an activity, I would have the students split into human body system groups. They would trace their body on a piece of white butcher paper and draw their specific system with a decent amount of accuracy (those with the skeletal system would draw bones inside the outline). I would hang them up in the hall for everyone to see. :)
