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.

    On a cold January day in 2017, nearly two months before her due date, Nile hippopotamus Bibi gave her keepers at the Cincinnati Zoo & Botanical Garden a big (little) surprise - a tiny newborn hippo, no bigger than a football.  The first premature hippo born and raised in captivity, baby Fiona was an underdog from the start:  she couldn't nurse, she couldn't stay hydrated, and she wasn't thriving. But the staff at the zoo knew they could save her.  It would take creative thinking and teamwork. They would have to study the makeup of hippo milk for the first time ever and reach out to medical colleagues, including a team at the local Children's Hospital with superior vein-finding skills,  to ensure that Fiona would begin to gain weight and become healthy. When Fiona began to thrive, her star began to rise, and soon she became an internet sensation, her picture and videos garnering thousands and thousands of likes and fans on Instagram and Facebook.  Now a Fiona appearance at the Zoo mimics a Beatles concert.  What made this little, now big, hippo such a big hit with people all over the world?  And what's in store for her and her family in the future?

    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.

    Young readers will learn how a British naturalist named Charles Darwin studied nature and developed his now-famous concepts of natural selection and survival of the fittest. And how modern-day science has added to our understanding of the theory of evolution. Can something as complex and wondrous as the natural world be explained by a simple theory? The answer is yes, and now Evolution explains how in a way that makes it easy to understand.

    Bob was a studious planner who wanted to grow up to be a doctor. Joe dreamed of making his fortune in show business and loved magic tricks and problem-solving.When an accident left Bob recovering in a darkened basement, the brothers began experimenting with ultraviolet light and fluorescent paints. Together they invented a whole new kind of color, one that glows with an extra-special intensity--Day-Glo.This cover reproduction is not printed with Day-Glo colors. The actual book, however, is printed using three Day-Glo colors: Saturn Yellow, Fire Orange, and Signal Green.

    Everywhere the House Sparrow went, it competed with humans for grain, becoming such a pest that in some places “sparrow catcher” became an actual job and bounties were paid to those who got rid of it.But not everyone hated the House Sparrow, and in 1852, fifty pairs were released in New York City. In no time at all, the bird had spread from coast to coast. Then suddenly, at the turn of the century, as cars took over from horses and there was less grain to be found, its numbers began to decline. As our homes, gardens, cities and farmland have changed, providing fewer nesting and feeding opportunities, the House Sparrow’s numbers have begun to decline again — though in England and Holland this decline appears to be slowing.

    Once again, the Bird and Bee are up to their antics, but this time they're younger.

    Flies are so much cooler! They flap their wings 200 times a second, compared to a butterfly's measly five to twelve times. Their babies—maggots—are much cuter than caterpillars (obviously). And when they eat solid food, they even throw up on it to turn it into a liquid. Who wouldn't want to study an insect like that?In an unforgettably fun, fact-filled presentation, this lovable (and highly partisan) narrator promotes his species to a sometimes engrossed, sometimes grossed-out, class of kids.

    They can be big, like a whale, tiny, like a shrimp, and even scary, like a shark.Even though sharks can be scary, we need them to keep the oceans healthy. Unfortunately, due to overfishing, many shark species are in danger of extinction, and that can cause big problems in the oceans and even on land.What would happen if this continued and sharks disappeared completely?Artist Lily Williams explores how the disappearance would affect other animals across the whole planet in this clever book about the importance of keeping sharks, and our oceans, healthy.
