The National Geographic Kids Bird Guide of North America will be both accessible and tons of fun. Fifty of the country's most popular birds will be laid out in stunning two-page spreads that will include information such as their range, the sounds they make, and the food they like to eat. Each profile will also include a cool or weird fun fact, and a feature called "A Closer Look," which digs deeper into once aspect of the bird's life (eating habits, birdsongs, etc.). Each profile will also display a fact box with the bird's scientific name, weight, length, and wingspan. Kids will also find tons of fun facts, bright and bold colors, full-color photographs, and layering of information that makes everything jump off the page. Birds will be organized by habitat, and habitat spreads will show where different birds live within each environment. The guide also explains all the basics that kids need to know about spotting birds. Features will include activities, such as how to build a birdhouse and how to build a birdfeeder, sidebars highlighting fascinating info, lists, range maps, and much more. Conservation information, a find out more section, glossary, and index will add ample back matter to round out this book.

    Her brother, Clive Campbell, spun the records. He had a new way of playing the music to make the breaks—the musical interludes between verses—longer for dancing. He called himself DJ Kool Herc and this is When the Beat Was Born. From his childhood in Jamaica to his youth in the Bronx, here's how Kool Herc came to be a DJ, how kids in gangs stopped fighting in order to breakdance, and how the music he invented went on to define a culture and transform the world.

    It's ever-present. Without it, you would die in minutes. And it has an epic story to tell.In Caesar's Last Breath, New York Times bestselling author Sam Kean takes us on a journey through the periodic table, around the globe, and across time to tell the story of the air we breathe, which, it turns out, is also the story of earth and our existence on it.With every breath, you literally inhale the history of the world. On the ides of March, 44 BC, Julius Caesar died of stab wounds on the Senate floor, but the story of his last breath is still unfolding; in fact, you're probably inhaling some of it now. Of the sextillions of molecules entering or leaving your lungs at this moment, some might well bear traces of Cleopatra's perfumes, German mustard gas, particles exhaled by dinosaurs or emitted by atomic bombs, even remnants of stardust from the universe's creation.Tracing the origins and ingredients of our atmosphere, Kean reveals how the alchemy of air reshaped our continents, steered human progress, powered revolutions, and continues to influence everything we do. Along the way, we'll swim with radioactive pigs, witness the most important chemical reactions humans have discovered, and join the crowd at the Moulin Rouge for some of the crudest performance art of all time. Lively, witty, and filled with the astounding science of ordinary life, Caesar's Last Breath illuminates the science stories swirling around us every second.

    This is essential reading for junior Egyptologists!

    It’s time. Today is the day he will once again cast himself into the air, spiral upward into the clouds, and bank into the wind.He wears a black band on his lower right leg and an orange flag on his upper left, bearing the laser inscription B95. Scientists call him the Moonbird because, in the course of his astoundingly long lifetime, this gritty, four-ounce marathoner has flown the distance to the moon—and halfway back! B95 is a robin-sized shorebird, a red knot of the subspecies rufa. Each February he joins a flock that lifts off from Tierra del Fuego, headed for breeding grounds in the Canadian Arctic, nine thousand miles away.  Late in the summer, he begins the return journey. B95 can fly for days without eating or sleeping, but eventually he must descend to refuel and rest. However, recent changes at ancient refueling stations along his migratory circuit—changes caused mostly by human activity—have reduced the food available and made it harder for the birds to reach. And so, since 1995, when B95 was first captured and banded, the worldwide rufa population has collapsed by nearly 80 percent. Most perish somewhere along the great hemispheric circuit, but the Moonbird wings on. He has been seen as recently as November 2011, which makes him nearly twenty years old. Shaking their heads, scientists ask themselves: How can this one bird make it year after year when so many others fall?  National Book Award–winning author Phillip Hoose takes us around the hemisphere with the world’s most celebrated shorebird, showing the obstacles rufa red knots face, introducing a worldwide team of scientists and conservationists trying to save them, and offering insights about what we can do to help shorebirds before it’s too late. Through prose, research, and images, Hoose explores the tragedy of extinction through the triumph of a single bird.

    They can be fully appreciated by an individual reader, but they're particularly striking when read aloud by two voices, making this an ideal pick for classroom use. Eric Beddows′s vibrant drawings send each insect soaring, spinning, or creeping off the page in its own unique way.With Joyful Noise, Paul Fleischman created not only a fascinating guide to the insect world but an exultant celebration of life.

    Breaking down the symbols themselves, they pose a series of questions: What is energy? What is mass? What has the speed of light got to do with energy and mass? In answering these questions, they take us to the site of one of the largest scientific experiments ever conducted. Lying beneath the city of Geneva, straddling the Franco-Swiss boarder, is a 27 km particle accelerator, known as the Large Hadron Collider. Using this gigantic machine—which can recreate conditions in the early Universe fractions of a second after the Big Bang—Cox and Forshaw will describe the current theory behind the origin of mass.Alongside questions of energy and mass, they will consider the third, and perhaps, most intriguing element of the equation: 'c' - or the speed of light. Why is it that the speed of light is the exchange rate? Answering this question is at the heart of the investigation as the authors demonstrate how, in order to truly understand why E=mc2, we first must understand why we must move forward in time and not backwards and how objects in our 3-dimensional world actually move in 4-dimensional space-time. In other words, how the very fabric of our world is constructed. A collaboration between two of the youngest professors in the UK, Why Does E=mc2? promises to be one of the most exciting and accessible explanations of the theory of relativity in recent years.

    With his trademark clarity and humor, Holt probes the mysteries of quantum mechanics, the quest for the foundations of mathematics, and the nature of logic and truth. Along the way, he offers intimate biographical sketches of celebrated and neglected thinkers, from the physicist Emmy Noether to the computing pioneer Alan Turing and the discoverer of fractals, Benoit Mandelbrot. Holt offers a painless and playful introduction to many of our most beautiful but least understood ideas, from Einsteinian relativity to string theory, and also invites us to consider why the greatest logician of the twentieth century believed the U.S. Constitution contained a terrible contradiction--and whether the universe truly has a future.

    But there was a time when people hunted the otters almost to extinction. Without sea otters to eat them, an army of hungry sea urchins grew and destroyed entire kelp forests. Fish and other animals that depended on the kelp were lost, too. But when people protected the sea otters with new laws, their numbers began to recover, and so did the kelp forests. Susannah Buhrman-Deever offers a beautifully written account of a trophic cascade, which happens when the removal of a single element affects an entire habitat. Asides that dig deeper are woven throughout Matthew Trueman’s dynamic illustrations, starring a raft of charismatic sea otters. Back matter includes more information about sea otters and kelp forests, including their importance and current status, the effects of the international fur trade on indigenous peoples, and a list of books and websites for readers who wish to continue to explore.
