You probably know that Leonardo da Vinci painted the Mona Lisa. Didyou know that he also invented an early version of a helicopter and a tank, and that he planned to execute the Time Warp Trio for spying on his inventions? Sam's bright idea to look for the inventor of the Book takes the guys to 15th century Italy to meet up with Leonardo. But it's going to take at least three more bright ideas, two magic tricks, and one great invention to get them out of trouble and safely back home. If not, it could be a lifetime of Italian army toilet-cleaning detail for Joe, Sam, and Fred.

When the Time Warp Trio travels back to fifteenth-century Italy to visit Leonardo da Vinci, the Renaissance master thinks they have come to spy on his inventions.

While on a field trip to New York's Museum of Natural History, Joe, Sam, and Fred travel one hundred years into the future, where they encounter robots, anti-gravity disks, and their own grandchildren.

The Maker Movement is hot, and librarians are eager to participate. Even if you feel restricted by budget, staff, or space, this step-by-step guide will help you turn your library into a creativity center. The Maker Movement is sweeping the nation because it is creative and educational—and a lot of fun. Nonetheless, some librarians have hesitated to incorporate the movement into their programming because their libraries do not have dedicated makerspaces. If that describes you, then take heart. Written by librarians for librarians, this "cookbook" proves that every library is already a MakerPlace and provides you with recipes to make your library come alive with creativity. Easy-to-use, step-by-step guidance helps you create engaging K–8 programs in science and technology, arts and crafts, and home skills that are perfect for the library setting. The menu of ideas is broken into four types of programming. "Appetizers" add a taste of the Maker movement to existing library programs. "Entrees" present full programs for a lengthy one-day event or a short series. "Side Dishes" are programs you can use if you have limited staff, budget, space, or any combination of those. "Desserts" are low-tech programs, suitable for young children. Each "recipe" includes extensions, variations, and curriculum tie-ins that give you even more ways to present the program ideas, whether to a different audience or as part of other related activities. Programs that involve creating a "Balloon Zip Line," a "Zen Garden," or a "Maker Marketplace" will delight library users and generate activity and excitement in your library.

Everyone’s favorite time-travelers are changing their styles! The Time Warp Trio series now features a brand-new, eye-catching design, sure to appeal to longtime fans, and those new to Jon Scieszka’s wacky brand of humor.

Joe, Fred, and Sam find themselves whisked by The Book to the main ring-ball court in Chichin Itza, Mexico in 1000 A.D., where they must play for their lives against a Mayan High Priest who cheats.

A Wall Street Journal Book of the Year A Spectator Book of the Year “A truly intimate portrait of one of the greatest creators in human history,” this biography of Leonardo Da Vinci “has the pace, elegance, and authorial omnipresence of a novel,” bringing both artist and Renaissance Italy to life (Noah Charney, author of The Art of Forgery) Why did Leonardo Da Vinci leave so many of his major works uncompleted? Why did this resolute pacifist build war machines for the notorious Borgias? Why did he carry the Mona Lisa with him everywhere he went for decades, yet never quite finish it? Why did he write backwards, and was he really at war with Michelangelo? And was he gay? In a book unlike anything ever written about the Renaissance genius, Mike Lankford explodes every cliché about Da Vinci and then reconstructs him based on a rich trove of available evidence—bringing to life for the modern reader the man who has been studied by scholars for centuries—yet has remained as mysterious as ever. Seeking to envision Da Vinci without the obscuring residue of historical varnish, the sights, sounds, smells, and feel of Renaissance Italy—usually missing in other biographies—are all here, transporting readers back to a world of war and plague and court intrigue, of viciously competitive famous artists, of murderous tyrants with exquisite tastes in art . . . Lankford brilliantly captures Da Vinci’s life as the compelling and dangerous adventure it seems to have actually been—fleeing from one sanctuary to the next, somehow surviving in war zones beside his friend Machiavelli, struggling to make art his way or no way at all . . . and often paying dearly for those decisions. It is a thrilling and absorbing journey into the life of a ferociously dedicated loner, whose artwork in one way or another represents his noble rebellion, providing inspiration that is timeless.
