But there was a time when these natural treasures were in great danger, all because after years of unrestricted hunting, one key piece of the puzzle had been eliminated-the wolf. Now, more than a decade after scientists realized the wolves' essential role and returned them to Yellowstone, the park's natural balance is gradually being restored. The informative dual-level text and spectacular full-color photographs show the wolves in the natural habitat that was almost lost without them. Readers of all ages will be inspired by the delicate natural system that is Yellowstone.

    One was white, one was Indian, and one was black. When the judges declared the white man the winner, the audience was outraged. They named black cowboy George Fletcher the "people's champion" and took up a collection, ultimately giving Fletcher far more than the value of the prize that went to the official winner. Award-winning author Vaunda Micheaux Nelson tells the story of Fletcher's unlikely triumph with a Western twang that will delight kids--and adults--who love true stories, unlikely heroes, and cowboy tales.

    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.

    New York City in the 1860s was a mess: crowded, disgusting, filled with garbage. You see, way back in 1860, there were no subways, just cobblestone streets. That is, until Alfred Ely Beach had the idea for a fan-powered train that would travel underground. On February 26, 1870, after fifty-eight days of drilling and painting and plastering, Beach unveiled his masterpiece—and throngs of visitors took turns swooshing down the track. The Secret Subway will wow readers, just as Beach’s underground train wowed riders over a century ago.

    But what if we took these big, hard-to-imagine objects and events and compared them to things we can see, feel and touch? Instantly, we'd see our world in a whole new way." So begins this endlessly intriguing guide to better understanding all those really big ideas and numbers children come across on a regular basis. Author David J. Smith has found clever devices to scale down everything from time lines (the history of Earth compressed into one year), to quantities (all the wealth in the world divided into one hundred coins), to size differences (the planets shown as different types of balls). Accompanying each description is a kid-friendly drawing by illustrator Steve Adams that visually reinforces the concept. By simply reducing everything to human scale, Smith has made the incomprehensible easier to grasp, and therefore more meaningful. The children who just love these kinds of fact-filled, knock-your-socks-off books will want to read this one from cover to cover. It will find the most use, however, as an excellent classroom reference that can be reached for again and again when studying scale and measurement in math, and also for any number of applications in social studies, science and language arts. For those who want to delve a little deeper, Smith has included six suggestions for classroom projects. There is also a full page of resource information at the back of the book.
