In an unusual twist on the school field trip theme, a second-grade boy named Sam manages to take the class hamster along on a visit to the science museum. The hamster, George Washington by name, has the distinguishing trait of frequent sneezing, which proves critically important when George Washington is dropped into the museum’s hamster display and must be retrieved. Lots of humorous details add to this mid-level easy reader’s appeal, and the story will be enjoyed by newly independent readers as well as serving as a read-aloud in any classroom (or home) with a hamster as a pet. Carter’s expressive watercolor illustrations help bring the kids in room 75 and their furry pet to life. (Easy reader. 5-8)
