Three young volunteers at the Metro City Science Museum discover they've actually volunteered for a great adventure after the museum's most prized exhibit is stolen by the evil Dr. Smasher. To recover it, they must use their knowledge of matter to survive an erupting volcano, operate a submarine, and ultimately outwit the wicked villain. Readers are invited to help fight crime, too, by learning about properties of matter and solving puzzles throughout this interactive adventure. This entertaining, high-interest volume, with its close ties to curricular content, is a motivating addition to any science collection.
