Then, suddenly, they died out. For thousands of years, no one knew these giant creatures had ever existed. Then people began finding fossils—bones and teeth and footprints that had turned to stone. Today, teams of experts work together to dig dinosaur fossils out of the ground, bone by fragile bone. Then they put the skeletons together again inside museums, to look just like the dinosaurs of millions of years 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.

    Stunning, realistic illustrations celebrate the beauty of these mysterious creatures as readers learn important facts through an engaging and fascinating story. The book also includes back matter with more in-depth information, a glossary, and further resources.

    This is because almost 70 percent of Earth's surface is covered with water. Earth is the only planet with liquid water --- and therefore the only planet that can support life. All water is connected. Every raindrop, lake, underground river and glacier is part of a single global well. Water has the power to change everything --- a single splash can sprout a seed, quench a thirst, provide a habitat, generate energy and sustain life. How we treat the water in the well will affect every species on the planet, now and for years to come. One Well shows how every one of us has the power to conserve and protect our global well. One Well is part of CitizenKid: A collection of books that inform children about the world and inspire them to be better global citizens.

    This true tale of horror begins in the leaf litter beside a quaint porch in Jackson, Mississippi. The wolfsnail is on the prowl. Big, strong, and fast (for a snail), the wolfsnail has a taste for meat. In some areas, it is called the cannibal snail. It has earned the name. Soon, the predator finds the slime trail of a smaller snail and follows the path toward its prey. When the chase ends and the dramatic feast is done, nothing remains of the smaller snail but an empty shell. This photographic story, a Theodor Seuss Geisel Honor Book, of a day in the life of a wolfsnail offers a unique and dramatic introduction to the food chain. Young readers will be fascinated by this little-known predator and the impact it has had on habitats where it does not belong.

    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.
