    When a professor discovered that the homework sent to him under a male pen name came from a woman...nothing stopped Sophie. And when she tackled a math problem that male scholars said would be impossible to solve...still, nothing stopped Sophie.For six years Sophie Germain used her love of math and her undeniable determination to test equations that would predict patterns of vibrations. She eventually became the first woman to win a grand prize from France's prestigious Academy of Sciences for her formula, which laid the groundwork for much of modern architecture (and can be seen in the book's illustrations).Award-winning author Cheryl Bardoe's inspiring and poetic text is brought to life by acclaimed artist Barbara McClintock's intricate pen-and-ink, watercolor, and collage illustrations in this true story about a woman who let nothing stop her.

    And just as compelling is the way the book is structured—hopscotching from country to country not by location but by type of attraction. For example, visit the site of the Tunguska event in Siberia, where a meteor slammed into the earth in 1908—and then skip over to the Yucatan, ground zero for the ancient meteor crash that caused the mass extinction of dinosaurs. Then, while in Mexico, tour the fantastical Naica caves, home to crystals ten times larger than the average person—then, turn the page to Vietnam to a cave so vast you  could fly a 747 through it. Illustrated in gorgeous and appropriately evocative full-color art, this book is a passport to a world of hidden possibilities.

    Few Parisians were willing to risk their own lives to help. Yet during that perilous time, many Jews found refuge in an unlikely place--the sprawling complex of the Grand Mosque of Paris. Not just a place of worship but a community center, this hive of activity was an ideal temporary hiding place for escaped prisoners of war and Jews of all ages, especially children.Beautifully illustrated and thoroughly researched (both authors speak French and conducted first-person interviews and research at archives and libraries), this hopeful, non-fiction book introduces children to a little-known part of history. Perfect for children studying World War II or those seeking a heart-warming, inspiring read that highlights extraordinary heroism across faiths.Includes a bibliography, a recommended list of books and films, and afterword from the authors that gives more details behind the story.

    Long ago, people grew afraid when each day had fewer hours of sunshine than the day before. Over time, they realized that one day each year the sun started moving toward them again. In lyrical prose and cozy illustrations, this book explains what the winter solstice is and how it has been observed by various cultures throughout history. Many contemporary holiday traditions were borrowed from ancient solstice celebrations. Simple science activities, ideas for celebrating the day in school and at home, and a further-reading list are included. Illustrated by Jesse Reisch.

    Using sunlight, landmarks, and scents to remember the path, she goes in search of pollen and nectar to share with the thousands of other bees in her hive. She uses her powerful sense of smell to locate the flowers that sustain her, avoids birds that might eat her, and returns home to share her finds with her many sisters. Nature lovers and scientists-to-be are invited to explore the fascinating life of a honey bee.
