Why don't we feel the Earth move? Why does an ice cube float? Why can't you unscramble an egg? Why can't we live forever? These are all questions that a curious kid might ask. In What's the BIG Idea?, renowned juvenile science educator Vicki Cobb answers these and other fascinating questions to help kids learn more about the world through the wonders of science. A big idea is one that has no simple or easy answer, and there are four big ideas in this book: motion, energy, matter, and life. The motion of nonliving objects—rolling balls, falling stones, the moon and stars—seems so ordinary and familiar that most people take it for granted. Matter, on the other hand, comes in so many different forms—solids, liquids, gases, metals, nonmetals, living material—that it is hard to imagine anything that all matter has in common. Energy is an idea that is in the news just about every day, yet most people couldn't tell you what the big idea of energy is. And life—what life is—seems mind-boggling and infinitely complicated. How do we bend our brains around it? Scientists learn by asking questions. And this book, now in paperback, is designed to make young readers stop and think about each of the questions before reading what scientists have learned that answers each question. They'll be able to do simple things to see for themselves, and they will build their own scientific knowledge in the process. By the time they've finished this book, they'll get the big picture of what science is all about.
Looks at how germs can spread such diseases as the common cold by following the journey of the germs that fly out of a boy's mouth when he sneezes in class without using a tissue, showing how colds spread or not depending on hygiene practices.
Intended to support the national initiative to strengthen learning in areas of science, technology, engineering, and mathematics, this book helps librarians who work with youth in school and public libraries to build better collections and more effectively use these collections through readers' advisory and programming. A versatile and multi-faceted guide, Best STEM Resources for NextGen Scientists: The Essential Selection and User's Guide serves as a readers' advisory and collection development resource for youth services and school librarians seeking to bring STEM-related titles into their collections and introduce teachers and young readers to them. This book not only guides readers to hundreds of the best STEM-related titles—fiction and non-fiction printed materials as well as apps, DVDs, websites, and games—it also includes related activities or programming ideas to help promote the use of the collection to patrons or students in storytime, afterschool programs, or passive library programs. After a detailed discussion of the importance of STEM and the opportunities librarians have for involvement, the book lists and describes best STEM resources for young learners. Resources are organized according to the reading audiences for which they are intended, from toddlers through teens, and the book includes annotated lists of both fiction and nonfiction STEM titles as well as graphic novels, digital products, and online resources. In addition, the author offers a selection of professional readings for librarians and media specialists who wish to further expand their knowledge.
