    "The Measly Middle Ages" portrays life as it really was in the days when knights were bold and the peasants were revolting.

    It had an illustration that captivated him–a diagram showing Earth’s interior as it would look if you cut into it with a large knife and removed about a quarter of its bulk. The idea of lots of startled cars and people falling off the edge of that sudden cliff (and 4,000 miles is a pretty long way to fall) was what grabbed him in the beginning, but gradually his attention turned to what the picture was trying to teach him: namely that Earth’s interior is made up of several different layers of materials, and at the very centre is a glowing sphere of iron and nickel, as hot as the Sun’s surface, according to the caption. And he very clearly remembers thinking: “How do they know that?”Bill’s storytelling skill makes the “How?” and, just as importantly, the “Who?” of scientific discovery entertaining and accessible for all ages. He covers the wonder and mystery of time and space, the frequently bizarre and often obsessive scientists and the methods they used, and the mind-boggling fact that, somehow, the universe exists and against all odds, life came to be on this wondrous planet we call home.

    An entertaining and informative illustrated guide  that makes world history accessible, appealing,  and funny.

    Children meet Bragi, the god of poetry, and the famous Valkyrie maidens, among other gods, goddesses, heroes, and giants. Illustrations throughout depict the wondrous other world of Norse folklore and its fantastical Northern landscape.

     Combining art, mythology, and science, What We See in the Stars gives readers a tour of the night sky through more than 100 magical pieces of original art, all accompanied by text that weaves related legends and lore with scientific facts. This beautifully packaged book covers the night sky's most brilliant features--such as the constellations, the moon, the bright stars, and the visible planets--as well as less familiar celestial phenomena like the outer planets, nebulae, and deep space. Adults seeking to recapture the magic of youthful stargazing, younger readers interested in learning about natural history and outer space, and those who appreciate beautiful, hand-painted art will all delight in this charming book.

    In early 2017, Senator Elizabeth Warren’s refusal to be silenced in the Senate inspired a spontaneous celebration of women who persevered in the face of adversity. In this book, Chelsea Clinton celebrates thirteen American women who helped shape our country through their tenacity, sometimes through speaking out, sometimes by staying seated, sometimes by captivating an audience. They all certainly persisted.She Persisted is for everyone who has ever wanted to speak up but has been told to quiet down, for everyone who has ever tried to reach for the stars but was told to sit down, and for everyone who has ever been made to feel unworthy or unimportant or small.With vivid, compelling art by Alexandra Boiger, this book shows readers that no matter what obstacles may be in their paths, they shouldn’t give up on their dreams. Persistence is power.This book features: Harriet Tubman, Helen Keller, Clara Lemlich, Nellie Bly, Maria Tallchief, Claudette Colvin, Ruby Bridges, Margaret Chase Smith, Sally Ride, Florence Griffith Joyner, Oprah Winfrey, Sonia Sotomayor—and one special cameo.

    Full of striking, singular art, this collection also contains infographics about relevant topics such as lab equipment, rates of women currently working in STEM fields, and an illustrated scientific glossary. The women profiled include well-known figures like primatologist Jane Goodall, as well as lesser-known pioneers such as Katherine Johnson, the African-American physicist and mathematician who calculated the trajectory of the 1969 Apollo 11 mission to the moon.

    Superb, full-color photographs offer a unique and revealing "eyewitness" view of this rich culture. See a necklace made of bear claws, a model of a Blackfeet teepee, a false face made from cornhusks, how fish were trapped in a basket, and a Cheyenne feathered war bonnet. Learn about the kachina ceremony, why love dolls were important, how turtle shells made music, what's stored inside a parfleche, and how pemmican was made. Discover the meanings of carvings on a Haida totem pole, what's inside an Iroquois longhouse, what medicine men carried in their medical kits, how a bow drill works, and much, much more.

    Full description

    / 'Cause whether his or hers amoeba, / They too feel like you and meba.What if a boring lesson about the food chain becomes a sing-along about predators and prey? A twinkle-twinkle little star transforms into a twinkle-less, sunshine-eating-and rhyming Black Hole? What if amoebas, combustion, metamorphosis, viruses, the creation of the universe are all irresistible, laugh-out-loud poetry? Well, you're thinking in science verse, that's what. And if you can't stop the rhymes ... the atomic joke is on you. Only the amazing talents of Jon Scieszka and Lane Smith, the team who created Math Curse, could make science so much fun.

    And, it's true, many of them do. But Paul Erdos never followed the usual path. At the age of four, he could ask you when you were born and then calculate the number of seconds you had been alive in his head. But he didn't learn to butter his own bread until he turned twenty. Instead, he traveled around the world, from one mathematician to the next, collaborating on an astonishing number of publications. With a simple, lyrical text and richly layered illustrations, this is a beautiful introduction to the world of math and a fascinating look at the unique character traits that made "Uncle Paul" a great man.

    Brought to life with lyrical text by award-winning author Donna Jo Napoli and stunning artwork by award-winning illustrator Christina Balit, the tales of gods and goddesses such as Zeus, Aphrodite, Apollo, and Athena and heroes and monsters such as Helen of Troy, Perseus, and Medusa will fascinate and engage children’s imaginations.   National Geographic completes the book with embellishments of each story: sidebars for each god, goddess, hero, and monster link the myths to constellations, geography, history, and culture to help young readers connect the stories to real life events, people, and places. A family tree and a “cast of characters” profile page help make relationships between the characters clear, and a mapping feature adds to the fun and fascination. Resource notes and ample back matter directing readers to more information round out this luminous book. Sure to dazzle all those intrigued with the fantastic tales of Greek mythology and enchant new readers, this vibrant book will soon become a family keepsake.National Geographic supports K-12 educators with ELA Common Core Resources.Visit www.natgeoed.org/commoncore for more information.

    But in his mind, he envisions himself traveling at a speed beyond imagining, on a beam of light. This brilliant mind will one day offer up some of the most revolutionary ideas ever conceived. From a boy endlessly fascinated by the wonders around him, Albert Einstein ultimately grows into a man of genius recognized the world over for profoundly illuminating our understanding of the universe. Jennifer Berne and Vladimir Radunsky invite the reader to travel along with Einstein on a journey full of curiosity, laughter, and scientific discovery. Parents and children alike will appreciate this moving story of the powerful difference imagination can make in any life.
