When it's not windy, it can be easy to forget about air. But air is everywhere–it fills your house, your car, and even your empty milk glass. In fact, a regular room holds about 75 pounds of it! This Level 1 book, reillustrated with John O'Brien's clever, eye–catching illustrations, tells you how to discover the air that's all around you.

Introduces the characteristics and importance of air.

Clean air is essential for all living creatures—plants, animals, and people—to live healthy lives. Every Breath We Take is a positive, life-affirming look at clean air, with a subtle message about how air can be dirtied—and how it can be cleaned up. Photographs of beautiful children around the world exploring air through touch, smell, sound, and sight underscore the importance of clean air to all life on earth. This is science that surrounds us. The first step to cherishing something is recognizing its importance and understanding why it is necessary. A portion of the proceeds from the sales of this book will be donated to Moms Clean Air Force, a national movement of over a half million moms, dads, and grandparents who are protecting the right of every child to breathe clean air.

Jandy Nelson's beloved, critically adored debut is now an Apple TV+ and A24 original film starring Jason Segel, Cherry Jones, Grace Kaufman, and Jacques Colimon. “Both a profound meditation on loss and grieving and an exhilarating and very sexy romance." —NPR Adrift after her sister Bailey’s sudden death, Lennie finds herself torn between quiet, seductive Toby—Bailey’s boyfriend who shares Lennie's grief—and Joe, the new boy in town who bursts with life and musical genius. Each offers Lennie something she desperately needs. One boy helps her remember. The other lets her forget. And she knows if the two of them collide, her whole world will explode. As much a laugh-out-loud celebration of love as a nuanced and poignant portrait of loss, Lennie's struggle to sort her own melody out of the noise around her makes for an always honest, often uproarious, and absolutely unforgettable read.

Up In The Air celebrates the nature around and above us, encouraging children to look, listen, and take notice. From cloud patterns to constellations, the chirrup of a single sparrow to the cacophony of the dawn chorus, and from trees that rustle in the wind to butterflies that flit about, this beautifully illustrated ebook encourages children to look, listen, and feel nature all around. Up In The Air looks at the habitats above our heads, uncovering the insects that make their homes in tree trunks and the animals that move from tree to tree in towering rainforests. It develops sky-watching skills so children can track the migration of birds and name the stars and planets of the night sky. As well as discovering the joy nature can bring to us, children will learn about how the living things inside this ebook are vital for our planet's future, whether they are insects pollinating plants or trees helping to make the air we breathe.

In the pantheon of air power spokesmen, Giulio Douhet holds center stage. His writings, more often cited than perhaps actually read, appear as excerpts and aphorisms in the writings of numerous other air power spokesmen, advocates-and critics. Though a highly controversial figure, the very controversy that surrounds him offers to us a testimonial of the value and depth of his work, and the need for airmen today to become familiar with his thought. The progressive development of air power to the point where, today, it is more correct to refer to aerospace power has not outdated the notions of Douhet in the slightest In fact, in many ways, the kinds of technological capabilities that we enjoy as a global air power provider attest to the breadth of his vision. Douhet, together with Hugh “Boom” Trenchard of Great Britain and William “Billy” Mitchell of the United States, is justly recognized as one of the three great spokesmen of the early air power era. This reprint is offered in the spirit of continuing the dialogue that Douhet himself so perceptively began with the first edition of this book, published in 1921. Readers may well find much that they disagree with in this book, but also much that is of enduring value. The vital necessity of Douhet’s central vision-that command of the air is all important in modern warfare-has been proven throughout the history of wars in this century, from the fighting over the Somme to the air war over Kuwait and Iraq.

Matter: Physical Science for Kids from the Picture Book Science series gets kids excited about science! What’s the matter? Everything is matter! Everything you can touch and hold is made up of matter—including you, your dog, and this book! Matter is stuff that you can weigh and that takes up space, which means pretty much everything in the world is made of matter. In Matter: Physical Science for Kids, kids ages 5 to 8 explore the definition of matter and the different states of matter, plus the stuff in our world that isn’t matter, such as sound and light! In this nonfiction picture book, children are introduced to physical science through detailed illustrations paired with a compelling narrative that uses fun language to convey familiar examples of real-world science connections. By recognizing the basic physics concept of matter and identifying the different ways matter appears in real life, kids develop a fundamental understanding of physical science and are impressed with the idea that science is a constant part of our lives and not limited to classrooms and laboratories. Simple vocabulary, detailed illustrations, easy science experiments, and a glossary all support exciting learning for kids ages 5 to 8. Perfect for beginner readers or as a read aloud nonfiction picture book! Part of a set of four books in a series called Picture Book Science that tackles different kinds of physical science (waves, forces, energy, and matter), Matter offers beautiful pictures and simple observations and explanations. Quick STEM activities such as weighing two balloons to test if air is matter help readers cross the bridge from conceptual to experiential learning and provide a foundation of knowledge that will prove invaluable as kids progress in their science education. Perfect for children who love to ask, “Why?” about the world around them, Matter satisfies curiosity while encouraging continual student-led learning.
