Arthur has to do a science fair project, but all of the good ideas are taken: Buster is building a rocket, Muffy is growing crystals, and Francine is making a bird feeder. Arthur learns a valuable lesson when he finds his father's old solar system project in the attic and tries to use it for his own science fair project. Includes two pages of stickers to help beginning readers create their own Arthur stories. From the Trade Paperback edition.
