Weaving science, history, culture, and folklore, awardwinning writer Albert Marrin offers a look at rats that goes from curious to repulsive, horrifying to comic, fearsome to inspiring. Arresting blackand- white scratchboard illustrations with bold red accents add visual punch to this study of a creature that has annoyed, disgusted, nourished, and intrigued its human neighbors throughout the centuries.

    Amazing new tools, materials and skills turn us all into makers. Using technology to make, repair or customize the things we need brings engineering, design and computer science to the masses. Fortunately for educators, this maker movement overlaps with the natural inclinations of children and the power of learning by doing. The active learner is at the center of the learning process, amplifying the best traditions of progressive education. This book helps educators bring the exciting opportunities of the maker movement to every classroom. Children are natural tinkerersTheir seminal learning experiences come through direct experience with materials. Digital fabrication, such as 3D printing and physical computing, including Arduino, MaKey MaKey and Raspberry Pi, expands a child’s toy and toolboxes with new ways to make things and new things to make. For the first time ever, childhood inventions may be printed, programmed or imbued with interactivity. Recycled materials can be brought back to life. While school traditionally separates art and science, theory and practice, such divisions are artificial. The real world just doesn’t work that way! Architects are artists. Craftsmen deal in aesthetics, tradition and mathematical precision. Video game developers rely on computer science. Engineering and industrial design are inseparable. The finest scientists are often accomplished musicians. The maker community brings children, hobbyists and professionals together in a glorious celebration of personal expression with a modern flare. When 3-D printing, precision cutting, microcomputer control, robotics and computer programming become integral to the art studio, auto shop or physics lab, every student needs access to tools, knowledge and problem solving skills. The maker movement not only blurs the artificial boundaries between subject areas, it erases distinctions between art and science while most importantly obliterating the crippling practice of tracking students in academic pursuits or vocational training. There are now multiple pathways to learning what we have always taught and things to do that were unimaginable just a few years ago. Making for every classroom budgetEven if you don’t have access to expensive (but increasingly affordable) hardware, every classroom can become a makerspace where kids and teachers learn together through direct experience with an assortment of high and low-tech materials. The potential range, breadth, power, complexity and beauty of projects has never been greater thanks to the amazing new tools, materials, ingenuity and playfulness you will encounter in this book. In this practical guide, Sylvia Martinez and Gary Stager provide K-12 educators with the how, why, and cool stuff that supports classroom making.

    Can you imagine that many of anything?The playful illustrations from New York Times–bestselling artist Isabel Greenberg and the friendly, straightforward voice of author Seth Fishman illuminate some of the biggest numbers in the universe—a hundred billion trillion stars—and the smallest—one unique and special YOU. Here is a book for story time, for science time, for math time, for bedtime, and all the times in between.Perfect for curious children, classrooms eager for STEM content, and readers who have devoured Ada Twist, Scientist and How Much Is a Million?

    Although he is an inventor, he has never made anything that works perfectly, and that's because he hasn't yet found a truly fantastic idea. But when he takes his family fishing on Lake Michigan, his daughter Virena asks, "Have you ever wondered what it's like to be a fish?"—and Papa is off to his workshop. With a lot of persistence and a little bit of help, Papa—who is based on the real-life inventor Lodner Phillips—creates a submarine that can take his family for a trip to the bottom of Lake Michigan.

    She is going to make the most MAGNIFICENT thing! She knows just how it will look. She knows just how it will work. All she has to do is make it, and she makes things all the time. Easy-peasy!? But making her magnificent thing is anything but easy, and the girl tries and fails, repeatedly. Eventually, the girl gets really, really mad. She is so mad, in fact, that she quits. But after her dog convinces her to take a walk, she comes back to her project with renewed enthusiasm and manages to get it just right.

    She blazed trails to the peaks of the male-centric worlds of education and law, where women had rarely risen before.Ruth Bader Ginsburg has often said that true and lasting change in society and law is accomplished slowly, one step at a time. This is how she has evolved, too. Step by step, the shy little girl became a child who questioned unfairness, who became a student who persisted despite obstacles, who became an advocate who resisted injustice, who became a judge who revered the rule of law, who became…RBG.

    “I smoked in my twenties. I preferred red wine to sparkling water. I ate too much milk chocolate. I liked limericks. I know all the wrong I’ve done. But also, more than any of that, I’ve always longed for children.” Yet there she was: successful, social, mostly happy, and not a mother. Knowing that her chances of becoming pregnant naturally were quickly fading, Finn decided to gamble: she—like some 85,000 other women in the U.S. each year—would attempt in vitro fertilization. Almost three years later, she’s still trying, and in the process has become an accidental pioneer (and, at times, a guinea pig) in the ever-evolving science of IVF.“The Baby Chase” is a primer for anyone contemplating or undergoing IVF. More than that, it’s a story of longing, hope—and hormones—that will appeal to all parents, present and future.Finn’s engaging and honest account sheds light on a subject that few people who undergo IFV are willing to talk about: what happens when the science doesn’t work. “Usually, it’s only the people who come out on the other side, beaming, with a baby on one hip, who speak up about IVF,” she writes. “We never hear from those IVF has failed - it’s too crushing to talk about. We don’t hear from men and women in the middle of treatment, either.... People like me.”

    Her endless curiosity eventually led to her career in diving and paleontology, where she would continue to find things big and small. In 1990, at a dig in South Dakota, Sue made her biggest discovery to date: Sue the T. rex, the largest and most complete T. rex skeleton ever unearthed. Named in Sue’s honor, Sue the T. rex would be placed on permanent exhibition at the Field Museum of Natural History in Chicago. When Sue Found Sue inspires readers to take a closer look at the world around them and to never lose their brave, adventurous spirits.

    Lilian tinkered and fiddled with all sorts of objects, turning dreams into useful inventions. As a child, she took apart and reassembled clocks to figure out how they worked. As an adult, typing up patents at the U.S. Patent Office, Lilian built the inventions in her mind, including many designs for flying machines. However, they all seemed too impractical. Lilian knew she could design one that worked. She took inspiration from both nature and her many failures, driving herself to perfect the design that would eventually successfully fly. Illustrator Tracy Subisak's art brings to life author Kirsten W. Larson's story of this little-known but important engineer.

    Now Sophie tells her story in this picture book that celebrates women in science, bugs of all kinds, and the importance of staying true to yourself.Sophia Spencer has loved bugs ever since a butterfly landed on her shoulder--and wouldn't leave--at a butterfly conservancy when she was only two-and-a-half years old. In preschool and kindergarten, Sophia was thrilled to share what she knew about grasshoppers (her very favorite insects), as well as ants and fireflies... but by first grade, not everyone shared her enthusiasm. Some students bullied her, and Sophia stopped talking about bugs altogether. When Sophia's mother wrote to an entomological society looking for a bug scientist to be a pen pal for her daughter, she and Sophie were overwhelmed by the enthusiastic response--letters, photos, and videos came flooding in. Using the hashtag BugsR4Girls, scientists tweeted hundreds of times to tell Sophia to keep up her interest in bugs--and it worked! Sophia has since appeared on Good Morning America, The Today Show, and NPR, and she continues to share her love of bugs with others.

    But, as adolescents are all too aware, there's a tremendous downside: When we do this to groups of people it can cause great harm. Here's a comprehensive introduction to the science behind stereotypes that will help young people make sense of why we classify people, and how we can change our thinking. It covers the history of identifying stereotypes, secret biases in our brains, and how stereotypes affect our sense of self. Most importantly, it covers current research into how science can help us overcome our biases, offering hope for a future where stereotypes are less prevalent and the world is more fair for everyone.Written by award-winning author Tanya Lloyd Kyi, this timely and hopeful book addresses the issues of discrimination, racism, sexism, ableism and homophobia and offers concrete suggestions on how to make change. It uses scientific inquiry and loads of relatable and interesting examples to explore these uncomfortable topics in age-appropriate and engaging ways. Chapters, sidebars and colorful illustrations break the text into manageable chunks. Besides the many ways this book could be used to inspire frank and in-depth discussions on the importance of addressing stereotypes and bias, it also links to many science and social studies curriculum topics. Back matter includes an extensive list of sources, suggestions for further reading and an index.

    but only half as tall as an ostrich, which is half as tall as a giraffe... twenty times smaller than a California Redwood! How do they compare to the tallest buildings? To Mt. Everest? To stars, galaxy clusters, and . . . the universe?

    She entered Ah-gwah-ching State Sanatorium at Walker, Minnesota, for what she thought would be a short stay. In January, her tuberculosis spread, and she nearly died. Her recovery required many months of bed rest and medical care.Marilyn loved to write, and the story of her three-year residency at the sanatorium is preserved in hundreds of letters that she mailed back home to her parents, who could visit her only occasionally and whom she missed terribly. The letters functioned as a diary in which Marilyn articulately and candidly recorded her reactions to roommates, medical treatments, Native American nurses, and boredom. She also offers readers the singular perspective of a bed-bound teenager, gossiping about boys, requesting pretty new pajamas, and enjoying Friday evening popcorn parties with other patients.Selections from this cache of letters are woven into an informative narrative that explores the practices and culture of a midcentury tuberculosis sanatorium and fills in long-forgotten details gleaned from recent conversations with Marilyn, who "graduated" from the sanatorium and went on to lead a full, productive life.

    But it's impossible for him to concentrate on his inventions when he's experiencing his own personal Big Bang.Arlo Brody is dividing the fourth grade boys into two groups. Waylon would rather be friends with everyone. Well, everyone except the scary new kid, Baxter Boylen.Waylon's older sister, Neon, is shooting away from the family. He wishes everything would go back to the way it was before she started wearing all black and saying "What's the point?" all the time.Just when it looks as though Waylon's universe is exploding, something happens to bring it all together again, and it is, without a doubt, One Awesome Thing.

    This is Nick's story of his world record-breaking adventure and the extraordinary people who joined him along the way. On January 6th 2018, Nick Butter tied his laces and stepped out on to an icy pavement in Toronto, where he began to take the first steps of an epic journey that would see him run 196 marathons in every one of the world's 196 countries. Spending almost two years on the road and relying on the kindness of strangers to keep him moving, Nick's odyssey allowed him to travel slowly, on foot, immersing himself in the diverse cultures and customs of his host nations. Running through capital cities and deserts, around islands and through spectacular landscapes, Nick dodges bullets in Guinea-Bissau, crosses battlefields in Syria, survives a wild dog attack in Tunisia and runs around an erupting volcano in Guatemala. Along the way, he is often joined by local supporters and fellow runners, curious children and bemused passers-by. Telling their stories alongside his own, Nick captures the unique spirit of each place he visits and forges a new relationship with the world around him. Running the World captures Nick's journey as he sets three world records and covers over five thousand miles. As he recounts his adventures, he shares his unique perspective on our glorious planet, celebrates the diversity of human experience, and reflects on the overwhelming power of running.
