Covering energy, plants and people, this book explains how almost all of our energy comes from the sun. It describes the process by which humans turn fuels and food into carbon dioxide to release energy, yet green leaves do exactly the opposite. The process of photosynthesis is explained in an easy-to-understand way, and children learn how plants turn light into electrical energy and use it to convert carbon dioxide and water into food.
In its essence, science is a way of looking at and thinking about the world. In The Life of a Leaf, Steven Vogel illuminates this approach, using the humble leaf as a model. Whether plant or person, every organism must contend with its immediate physical environment, a world that both limits what organisms can do and offers innumerable opportunities for evolving fascinating ways of challenging those limits. Here, Vogel explains these interactions, examining through the example of the leaf the extraordinary designs that enable life to adapt to its physical world. In Vogel’s account, the leaf serves as a biological everyman, an ordinary and ubiquitous living thing that nonetheless speaks volumes about our environment as well as its own. Thus in exploring the leaf’s world, Vogel simultaneously explores our own.

Lois Ehlert uses watercolor collage and pieces of actual seeds, fabric, wire, and roots in this innovative and rich introduction to the life of a tree. A special glossary explains how roots absorb nutrients, what photosynthesis is, how sap circulates, and other facts about trees. "Children will beg to share this book over and over."--American Bookseller

A leaf is a leaf, a bit of a tree. But just try to guess what else it can be! A leaf can be a...shade spiller, mouth filler, tree topper, rain stopper. Find out about the many roles leaves play in this poetic exploration of leaves throughout the year. Laura Purdie Salas's lyrical, rhyming text and Violeta Dabija's glowing illustrations make simple yet profound observations about seemingly ordinary objects and encourage readers to suggest "what else it can be!" Using metaphors for a leaf (tree topper / rain stopper), a rock (hopscotch marker / fire sparker), and water (thirst quencher / kid drencher), these insightful picture books creatively highlight a variety of roles and relationships in nature.
The brilliant colors of fall foliage take center stage in this picture book perfect for fans of the classic Red Leaf, Yellow Leaf. With her trademark bold, graphic style Monica Wellington has created a picture book about autumn, trees, and leaves. When the seasons change, a young girl visits the arboretum to collect fallen leaves and make a book with them. Brilliant illustrations show each variety of tree the girl encounters, from the common oak to the lesser known gingko. Spreads silhouetting leaves up-close help young children learn to identify them. Like the girl in the book, young readers will be eager to make their very own leaf books.
One of the best ways to understand history is through eye-witness accounts. Ting-Xing Ye’s riveting first book, A Leaf in the Bitter Wind, is a memoir of growing up in Maoist China. It was an astonishing coming of age through the turbulent years of the Cultural Revolution (1966 - 1974). In the wave of revolutionary fervour, peasants neglected their crops, exacerbating the widespread hunger. While Ting-Xing was a young girl in Shanghai, her father’s rubber factory was expropriated by the state, and he was demoted to a labourer. A botched operation left him paralyzed from the waist down, and his health deteriorated rapidly since a capitalist’s well-being was not a priority. He died soon after, and then Ting-Xing watched her mother’s struggle with poverty end in stomach cancer. By the time she was thirteen, Ting-Xing Ye was an orphan, entrusted with her brothers and sisters to her Great-Aunt, and on welfare. Still, the Red Guards punished the children for being born into the capitalist class. Schools were being closed; suicide was rampant; factories were abandoned for ideology; distrust of friends and neighbours flourished. Ting-Xing was sent to work on a distant northern prison farm at sixteen, and survived six years of backbreaking labour and severe conditions. She was mentally tortured for weeks until she agreed to sign a false statement accusing friends of anti-state activities. Somehow finding the time to teach herself English, often by listening to the radio, she finally made it to Beijing University in 1974 as the Revolution was on the wane — though the acquisition of knowledge was still frowned upon as a bourgeois desire and study was discouraged. Readers have been stunned and moved by this simply narrated personal account of a 1984-style ideology-gone-mad, where any behaviour deemed to be bourgeois was persecuted with the ferocity and illogic of a witch trial, and where a change in politics could switch right to wrong in a moment. The story of both a nation and an individual, the book spans a heady 35 years of Ye’s life in China, until her eventual defection to Canada in 1987 — and the wonderful beginning of a romance with Canadian author William Bell. The book was published in 1997. The 1990s saw the publication of several memoirs by Chinese now settled in North America. Ye’s was not the first, yet earned a distinguished place as one of the most powerful, and the only such memoir written from Canada. It is the inspiring story of a woman refusing to “drift with the stream” and fighting her way through an impossible, unjust system. This compelling, heart-wrenching story has been published in Germany, Japan, the US, UK and Australia, where it went straight to #1 on the bestseller list and has been reprinted several times; Dutch, French and Turkish editions will appear in 2001.
Fall has come, the wind is gusting, and Leaf Man is on the move. Is he drifting east, over the marsh and ducks and geese? Or is he heading west, above the orchards, prairie meadows, and spotted cows?

With illustrations made from actual fall leaves and die-cut pages on every spread that reveal gorgeous landscape vistas, here is a playful, whimsical, and evocative book that celebrates the natural world and the rich imaginative life of children. Includes an author's note and leaf-identifying labels.
