Ms. Frizzle's class goes on an adventure exploring the microscopic world of microbes in this Magic School Bus science chapter book. Ms. Frizzle has a magic school bus that can take her students on amazing field trips anywhere in the universe, and this time, the start by shrinking down to explore the mold on the homemade bread in Keesha's lunch. From there, the class explored a compost heap and even the inside of poor, sick Jimmy's blood vessels and were nearly engulfed by a white blood cell! This was an exciting, fast-paced look at many of the different types of microbes, their usefulness, and their dangers. In the end, the students learn that microbes are EVERYWHERE and regular hand washing is very important.
This is quite definitely a book in the fantasy genre, as a teacher could never really shrink a school bus and explore a classmate's blood vessels, using a special shield to keep the bus clean and dry on the inside. It is fun to imagine the idea, however, and to get an up-close and personal look into a world we cannot easily see. What makes this fantasy fun is the scientific notes that the students take throughout the adventure as they learn the true world of microscopic life.
This would make an excellent flu season read-aloud that teaches students all about bacteria and viruses that fly around when we sneeze and cough. I would have students create posters detailing what they learned from the book about the way germs travel, how to prevent infections, as well as the way that many microbes are useful. Older students could write their own Magic School Bus type adventure/research projects. Students would really enjoy imagining their own adventure where they could really get "into" science!
This book's reading level is listed as a 4.7 grade level equivalent, most likely because of all of the scientific vocabulary it contains. I think that 3-5th graders would enjoy the story as a read-aloud and be able to learn quite a lot from it if enough time is devoted to creating a word wall or doing other vocabulary activities.
