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.

    As we dream with him, we are taken further and further into mathematical theory, where ideas eventually take flight, until everyone--from those who fumble over fractions to those who solve complex equations in their heads--winds up marveling at what numbers can do.Hans Magnus Enzensberger is a true polymath, the kind of superb intellectual who loves thinking and marshals all of his charm and wit to share his passions with the world. In The Number Devil, he brings together the surreal logic of Alice in Wonderland and the existential geometry of Flatland with the kind of math everyone would love, if only they had a number devil to teach them.

    In fact, five of them could fit into the period at the end of this sentence.On a clear, warm Sunday, April 14, 1935, a wild wind whipped up millions upon millions of these specks of dust to form a duster—a savage storm—on America's high southern plains.The sky turned black, sand-filled winds scoured the paint off houses and cars, trains derailed, and electricity coursed through the air. Sand and dirt fell like snow—people got lost in the gloom and suffocated . . . and that was just the beginning.Don Brown brings the Dirty Thirties to life with kinetic, highly saturated, and lively artwork in this graphic novel of one of America's most catastrophic natural events: the Dust Bowl.

    Their creations are some of the most enduring (the windshield wiper) and best loved (the chocolate chip cookie). What inspired these women, and just how did they turn their ideas into realities?Features women inventors Ruth Wakefield, Mary Anderson, Stephanie Kwolek, Bette Nesmith Graham, Patsy O. Sherman, Ann Moore, Grace Murray Hopper, Margaret E. Knight, Jeanne Lee Crews, and Valerie L. Thomas, as well as young inventors ten-year-old Becky Schroeder and eleven-year-old Alexia Abernathy.

    He was such a daydreamer that people called him a blockhead.When Leonardo grew up and traveled the world, he was inspired by the numbers used in different countries. Then he realized that many things in nature, from the number of petals on a flower to the spiral of a nautilus shell, seem to follow a certain pattern. The boy who was once teased for being a blockhead had discovered what came to be known as the Fibonacci Sequence!

    Sometimes you need to see things for yourself—at their actual size.

    As a young genius living in a time before science as we know it existed, Isaac studied the few books he could get his hands on, built handmade machines, and experimented with alchemy--a process of chemical reactions that seemed, at the time, to be magical. Mary Losure's riveting narrative nonfiction account of Isaac's early life traces his development as a thinker from his childhood, in friendly prose that will capture the attention of today's budding scientists--as if by magic. Back matter includes an afterword, an author's note, source notes, a bibliography, and an index.

    Huge numbers are hard to comprehend. This book explains quantities in terms children can understand. For example, one million dollars could buy two full pizzas a day for more than sixty-eight years.

    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.

    Bugs, of all kinds, were considered to be “born of mud” and to be “beasts of the devil.”  Why would anyone, let alone a girl, want to study and observe them? One of the first naturalists to observe live insects directly, Maria Sibylla Merian was also one of the first to document the metamorphosis of the butterfly. In this nonfiction biography, illustrated throughout with full-color original paintings by Merian herself, author Joyce Sidman paints her own picture of one of the first female entomologists and a woman who flouted convention in the pursuit of knowledge and her passion for insects.
