In the garbage

Andrew, Judy, and Thudd have time-traveled out of an ice age only to find themselves shrunk down and tossed out with the garbage! As they get up close and personal with half-eaten hog dogs, soggy pasta, and old fruit rinds, they'll learn about the stinky--but oh-so-necessary!--process of decomposition. Kids, parents, and teachers love this series--kids for all its gooey grossness, and teachers and parents for all the fun science and great discussion points!From the Trade Paperback edition.
