    And just as compelling is the way the book is structured—hopscotching from country to country not by location but by type of attraction. For example, visit the site of the Tunguska event in Siberia, where a meteor slammed into the earth in 1908—and then skip over to the Yucatan, ground zero for the ancient meteor crash that caused the mass extinction of dinosaurs. Then, while in Mexico, tour the fantastical Naica caves, home to crystals ten times larger than the average person—then, turn the page to Vietnam to a cave so vast you  could fly a 747 through it. Illustrated in gorgeous and appropriately evocative full-color art, this book is a passport to a world of hidden possibilities.

    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.

    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.

    I want you to panic…I want you to act as if our house is on fire. Because it is. When she was fifteen years old, Greta Thunberg’s teacher explained to her class that our climate is changing—the earth is getting warmer, the polar ice caps are melting, and life on earth is threatened. Greta was devastated. What could she do? If the grown-ups weren’t doing enough to save the planet, Greta would have to demand change herself. So she went on strike, skipping school every Friday to sit outside of the Swedish Parliament building with a sign that read “School Strike for Climate.” At first, Greta was the only one. But gradually, more and more students joined her, until her lone protest had sparked a worldwide student movement for action on climate change. Now, a year later, Greta is speaking to audiences of world leaders at important meetings like the United Nations Climate Conference and the World Economic Forum. She is leading the conversation on climate change and sparking worldwide conversation on how to save our planet. Greta is showing everyone that even the smallest person can make a big difference, and this picture book informs and inspires young readers who are beginning to learn about the world around them.
