Arthur Turns Green

When his class embarks on a "Big Green Machine" project "to find ways to make our planet a better place to live," Arthur focuses on turning his household green by recycling, unplugging his mom's cellphone charger, and replacing conventional light bulbs with energy-saving bulbs. His younger sister, D.W., however, is worried about the "big machine," especially when Arthur comes home with green hands (from making a poster), and she dreams about a monster turning everyone green. Her misunderstanding (which is righted in the end) adds a welcome dollop of humor to the story as perennially favorite characters bring home the message about conservation. Ages 3–6. (Apr.)
