    Long ago, people grew afraid when each day had fewer hours of sunshine than the day before. Over time, they realized that one day each year the sun started moving toward them again. In lyrical prose and cozy illustrations, this book explains what the winter solstice is and how it has been observed by various cultures throughout history. Many contemporary holiday traditions were borrowed from ancient solstice celebrations. Simple science activities, ideas for celebrating the day in school and at home, and a further-reading list are included. Illustrated by Jesse Reisch.

    Helens, a volcano in southern Washington State. Minutes later, Mount St. Helens blew the top off its peak and exploded into the most devastating volcanic eruption in U.S. history.What caused the eruption? What was left when it ended? What did scientists learn in its aftermath?In this extraordinary photographic essay, Patricia Lauber details the Mount St. Helens eruption and the years following. Through this clear accurate account, readers of all ages will share the awe of the scientists who witnessed both the power of the volcano and the resiliency of life.

    A lively and inspiring poem weaves together facts about water and the need for water conservation.

    He protected roots through harsh winters, so plants could be reborn in the spring. He trimmed flowers, spread soil, studied life cycles. And it was in this very place that George’s love of nature sprouted into something so much more—his future.

    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.

    He had discovered a humpback whale tangled in hundreds of yards of crab-trap lines, struggling to stay at the surface to breathe. A team of volunteers answered the call, and four divers risked their lives to rescue the enormous animal. What followed was a rare and remarkable demonstration of animal behavior. This celebrated story, beautifully depicted in Jennifer O'Connell's mesmerizing paintings, will make you wonder about animal emotions and the unique connections we can have with animals, even whales.

    A lively text and striking illustrations provide a revelatory account of the planet's dramatic formation.

    It presents the important traditional content of mineralogy including crystallography, chemical bonding, controls on mineral structure, mineral stability, and crystal growth to provide a foundation that enables students to understand the nature and occurrence of minerals. Physical, optical, and X-ray powder diffraction techniques of mineral study are described in detail, and common chemical analytical methods are outlined as well. Detailed descriptions of over 100 common minerals are provided, and the geologic context within which these minerals occur is emphasized. Appendices provide tables and diagrams to help students with mineral identification, using both physical and optical properties. Numerous line drawings, photographs, and photomicrographs help make complex concepts understandable. Introduction to Mineralogy not only provides specific knowledge about minerals but also helps students develop the intellectual tools essential for a solid, scientific education. This comprehensive text is useful for undergraduate students in a wide range of mineralogy courses.

    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.

    We are like wizards.The story of a tree is a story of community, communication, and cooperation. Although trees may seem like silent, independent organisms, they form a network buzzing with life: they talk, share food, raise their young, and offer protection. Trees thrive on diversity, learn from their ancestors, and give back to their communities. Trees not only sustain life on our planet—they can also teach us important lessons about patience, survival, and teamwork.A New York Public Library Best Book of 2021A New York Public Library Top Ten Book for Kids

    Explains how fossils are formed and what they tell us about the past.

     In Elkhorn Slough, an inlet on the California coast, seagrass grows healthy and strong in the shallow water. This healthy seagrass baffled marine biologist Brent Hughes. The scientist expected this estuary to be overrun with algae, causing the seagrass to die. Why was the seagrass thriving? As Brent investigated, signs pointed to an unexpected player helping to keep the seagrass healthy: sea otters! What do these top predators have to do with an aquatic grass at the opposite end of the food chain? Brent's discovery gave scientists insight into the delicate balance of ecosystems. Follow science in action as Brent conducts the research that led to this major discovery.
