But water doesn't always look the same, it doesn't always feel the same, and it shows up in lots of different shapes. Water can be a lake, it can be steam, it can be a tear, or it can even be a snowman.As the girl discovers water in nature, in weather, in her home, and even inside her own body, water comes to life, and kids will find excitement and joy in water and its many forms.

    When she was just twelve years old, Mattie designed a metal guard to prevent shuttles from shooting off textile looms and injuring workers. As an adult, Mattie invented the machine that makes the square-bottom paper bags we still use today. However, in court, a man claimed the invention was his, stating that she “could not possibly understand the mechanical complexities.” Marvelous Mattie proved him wrong, and over the course of her life earned the title of “the Lady Edison.”   With charming pen-and-ink and watercolor illustrations, this introduction to one of the most prolific female inventors will leave readers inspired.   Marvelous Mattie is a 2007 Bank Street - Best Children's Book of the Year.

    They can be big, like a whale, tiny, like a shrimp, and even scary, like a shark.Even though sharks can be scary, we need them to keep the oceans healthy. Unfortunately, due to overfishing, many shark species are in danger of extinction, and that can cause big problems in the oceans and even on land.What would happen if this continued and sharks disappeared completely?Artist Lily Williams explores how the disappearance would affect other animals across the whole planet in this clever book about the importance of keeping sharks, and our oceans, healthy.

    She explored the forest in her backyard, observing woodland creatures, and used her house as a model to build tiny towns out of paper and scraps. The daughter of a clay artist and a poet, Maya grew up with art and learned to think with her hands as well as her mind. From her first experiments with light and lines to the height of her success nationwide, this is the story of an inspiring American artist: the visionary artist-architect who designed the Vietnam Veterans Memorial.

    

    But it doesn't really. The moon revolves around the Earth. It takes about four weeks to make the journey, and as it travels round we can only see certain parts of it. Try the simple experiment described inside using an orange, a pencil, and a flashlight, and you'll understand why the moon seems to change.

    Sometimes, they bloom a few at a time. But other times, many will bloom at once in a colorful flower boom! This photographic exploration of flowers goes from the desert to the woodlands and beyond, celebrating their beautiful variety and the science behind these colorful displays.

    Her parents separated when she was young, and her mother insisted on a logic-focused education, rejecting Byron’s “mad” love of poetry. But Ada remained fascinated with her father and considered mathematics “poetical science.” Via her friendship with inventor Charles Babbage, she became involved in “programming” his Analytical Engine, a precursor to the computer, thus becoming the world’s first computer programmer. This picture book biography of Ada Lovelace is a portrait of a woman who saw the potential for numbers to make art.

    King Arthur was a good ruler, but now he needs a good ruler. What would you do if the neighboring kingdom were threatening war? Naturally, you'd call your strongest and bravest knights together to come up with a solution. But when your conference table causes more problems than the threat of your enemy, you need expert help. Enter Sir Cumference, his wife Lady Di of Ameter, and their son Radius. With the help of the carpenter, Geo of Metry, this sharp-minded team designs the perfect table conducive to discussing the perfect plan for peace. The first in Sir Cumference series, SIR CUMFERENCE AND THE FIRST ROUND TABLE makes math fun and accessible for everyone.

    And they did so during a time when being black and a woman limited what they could do. But they worked hard. They persisted. And they used their genius minds to change the world.In this illustrated picture book edition, we explore the story of four female African American mathematicians at NASA, known as "colored computers," and how they overcame gender and racial barriers to succeed in a highly challenging STEM-based career.

    From checking bags and watching them disappear on the mysterious conveyor belt, to security clearance and a seemingly endless wait at the gate to finally being airborne.But wait! There's more! The youngest family member's sock monkey has gone missing. Follow it at the bottom of the page as it makes a journey as memorable as that of the humans above.

    The steps are described in simple but evocative text, each starting with “Before . . .” for a rhythmic telling. For example, “Before we stood tall, we clothed ourselves in bark and crowned ourselves in leaves, waving eagerly at the sun.” Particular attention is paid throughout to what's happening underground and how that links all life in the forest. Beginning with mature giants, “mighty in the kingdom of trees,” and ending with the promise of new life on the branches that are “hoping to be mighty in the kingdom of trees,” it's a beautiful and loving celebration of the circle of life.Jessica Kulekjian's skill at seamlessly blending nonfiction information with a poetic narrative sets this informational picture book apart. She also uniquely incorporates intriguing new research on how trees communicate with each other using an underground network of roots and fungus that connects the forest and helps the trees to thrive. Madeline Kloepper's rich artwork with its deep earth tone palette brings the forest and all its inhabitants alive on the page. The material has been vetted by several scientists, including experts on trees, insects and mushrooms. Supported by well-researched backmatter, the book has strong curriculum links to early elementary earth and life science topics, including plants, ecosystems and soil.

    But have you ever heard of a butterfly farm? How do you raise a butterfly? On a farm in Costa Rica, workers care for these delicate, winged creatures as they change from eggs to caterpillars to pupae. Like any other crop, the butterflies will eventually leave the farm. But where will they go? And just how do you ship a butterfly? Very carefully! To discover how it works, follow these butterflies on a remarkable journey!

    Fractals can also be quantified mathematically. Here is an elegant introduction to fractals through examples that can be seen in parks, rivers, and our very own backyards. Readers will be fascinated to learn that broccoli florets are fractals—just like mountain ranges, river systems, and trees—and will share in the wonder of math as it is reflected in the world around us. Perfect for any elementary school classroom or library, Mysterious Patterns is an exciting interdisciplinary introduction to repeating patterns.

    Newbery Honor-winning poet Joyce Sidman presents another unusual blend of fine poetry and fascinating science illustrated in exquisite hand-colored linocuts by Caldecott Honor artist Beckie Prange.Ubiquitous (yoo-bik-wi-tuhs): Something that is (or seems to be) everywhere at the same time.Why is the beetle, born 265 million years ago, still with us today? (Because its wings mutated and hardened). How did the gecko survive 160 million years? (By becoming nocturnal and developing sticky toe pads.) How did the shark and the crow and the tiny ant survive millions and millions of years? When 99 percent of all life forms on earth have become extinct, why do some survive? And survive not just in one place, but in many places: in deserts, in ice, in lakes and puddles, inside houses and forest and farmland? Just how do they become ubiquitous?
