The Magic School Bus In A Pickle: A Book About Microbes - Joanna Cole, Bob Ostrom, Joanna Cole, Bruce Degen
Explains (very, very simply) how microbes change food (for better or worse). A good book to incorporate with a unit on microbes - particularly if you've been focused on only the very nasty kinds of germs. This smaller tv-series tie-in format isn't my favorite with regards to the Magic School Bus series, but I still think it will appeal to children who are familiar with and enjoy the series. Also, a great one to read before you take on a pickling project with a kiddo. In fact, wish they'd included a kid-friendly recipe/pickling method at the pack. We're using the one found here - although I can't vouch for it quite yet!
