Acclaimed Caldecott Artist Molly Bang teams up with award-winning M.I.T. professor Penny Chisholm to present the fascinating, timely story of fossil fuels. What are fossil fuels, and how did they come to exist? This engaging, stunning book explains how coal, oil, and gas are really "buried sunlight," trapped beneath the surface of our planet for millions and millions of years.Now, in a very short time, we are digging them up and burning them, changing the carbon balance of our planet's air and water.

When Mollys pet cat dies, Mollys tears turn to wonder and eventually joy, as she finds out about atoms and how the atoms of her cat will be reused and become part of other plants and creatures in the future. In this journey of discovery, she realises that if the atoms continually get reused in the future, then they must have also done so in the past, and she speculates about what famous people or intriguing creatures may have once used the atoms that she now possesses. This leads her to wonder where these atoms came from in the first place, and she skips for joy and she is amazed when she discovers the answer.

"I have never had another friendship like that I had with Molly. One loves only once with such intensity and devotion." Inspired by the literary classic Lolita, this extraordinary debut novel is a richly imagined coming-of-age story about two girls in Illinois in the 1940s and their intense, erotically charged friendship, which endures even after one moves away and becomes entangled in a disturbing life with her new stepfather. Shy, intelligent, and fiercely loyal, Betsy Thurmont longs to shed her awkward reserve and be more like her best friend, Molly Liddell, a vivacious, dazzling girl who charms all who know her. They are a devoted pair, jitterbugging at the local soda shop, ice skating at the rink, taking a blood oath that they will never part -- until Molly's mother is caught up in scandal and flees far away with her daughter. Years later, Betsy comes into possession of Molly's diaries and learns the startling story of what happened to her childhood friend. Through her diary entries, Molly tells the dramatic story of her mother's marriage to a European scholar named Richard Richard, with whom Molly begins an outrageous flirtation. But, after her mother's death, this man uses her preadolescent seductions to fulfill his own ruthless desires. Heartbreaking in their honesty, Molly's diaries eloquently express how a bright future can be dimmed by circumstance. Guided by Molly's strong and resilient voice, Betsy reaches her own epiphany about the meaning of her dear friend's short life, and about her own place in the world. Molly perfectly captures the wonderment, longing, fear, and frustration of making the potentially dangerous yet exhilarating metamorphosis from girl to woman. This radiant first novel is also a loving tribute to Vladimir Nabokov and his classic work, invoking the spirit of the legendary Lolita.

Greek philosophers first hypothesized that matter was composed of atoms, but the theory would not resurface again until the late 17th century. The idea that that atoms joined to form structures called molecules first appeared in the 19th century and helped explain why gases, liquids, and solids behave differently from one another. In the 20th century subatomic particles were discovered—electrons, protons, and neutrons—and atomic structure was finally understood. These breakthroughs led to the development of quantum theory and quantum mechanics. This book details the inspiring and heroic discovery, delving deeply into intriguing stories, reviewing major scientific landmarks, and introducing readers to the vivid men and women who helped discover and map the microscopic universe that is the atom. Supplemental content includes an activity spread, a substantial and highly detailed timeline, and a list of key people with mini-biographies.

Young readers will be amazed to learn about the tiny particles that make up everything in the world around them. Colorful illustrations and fun fact boxes will help readers understand how atoms come together to form molecules, the building blocks of everything in the universe.
