This is a story about sand and how science and silicon changed our lives. Over the last century, science taught us how to take this most common material and create the products on which we depend. It allows us to determine the atomic structure of materials and to grow novel, new materials atomic layer by atomic layer. The principles of thermodynamics are used to transform sand into ultra pure silicon. Quantum mechanics gave birth to the electronic age and the computer chip in which dopants are precisely placed in ultra pure silicon. The absorption and emission and reflection of quanta of light, photons, underlies solar cells, light emitting diodes, radiation detectors and optical fibers. This book follows the history of these scientific discoveries and relates them to the products made from sand.

Young children are intuitive, emergent scientists - they observe, raise hypotheses, experiment and notice patterns. Most of our everyday actions at home and in other settings, inside and outside, have a scientific basis and it is through these early experiences that children formulate their ideas about the world in which we live. This accessible book introduces the simplest form of the principles and the big ideas of science and provides a starting point for encouraging children to have an interest and experiential understanding of basic science and engineering. It shows you how you can support young children in exploring everyday phenomena and develop their scientific language skills through readily available resources and hands-on experiences. Each chapter focuses on a different aspect of science and includes: a summary of the ‘big ideas’ to refresh your own scientific knowledge; numerous activities that encourage young children to observe, question and carry out their own investigations; a usefil list of everyday resources and relevant vocabulary. Providing a wealth of exciting, meaningful ways to promote scientific experiences and learning, this highly practical book will help you to build on children’s natural curiosity about the world and develop their understanding through your everyday provision in early years settings and at home.

Praise for Be the Solution "In the past, many believed you either went into 'public service' to do good, or you 'went into business' to make money. Few realized that the long-term success of business depends on serving people, not making money. Few realized that perhaps the best way to serve the public was through free enterprise. Whole Foods Market founder John Mackey, visionary thinker Michael Strong, micro lender Muhammad Yunus, and a few others understand these truths. Be the Solution is the best single book to read to understand the emerging ways in which entrepreneurs can change the world." —Gary Hoover, serial entrepreneur, founder of Hoover's Business Information Service, Hooversworld.com "Michael Strong speaks the truth. A must-read for our new American government." —Sam Wyly, founder, Green Mountain Energy; author of 1,000 Dollars and an Idea "This book is totally fantastic. Treat your mind to a feast. Use it to tune your vision towards what really works." —Charles Harper, Senior Executive VP, Chief Strategist, John Templeton Foundation "Perhaps more than ever before, young people today are motivated by the desire to make the world a better place. Unfortunately, many have little idea about how to do it, and their educational studies provide them with little direction. In contrast, this book is a road map about how we can get from where we are to where we want to be—to a more peaceful, more prosperous, and more environmentally sound world. Plus, it is exciting, uplifting, and adventurous. Indeed, it provides the recipe for a better world." —Dr. James Gwartney, coauthor of Economic Freedom of the World: 2007 Annual Report; Gus A. Stavros Eminent Scholar Chair at Florida State University "This is a very thoughtful and timely book that asks us to look around—and to look within—the amazing opportunities that entrepreneurship offers to the world. I recommend this book to anyone interested in finding solutions to the current crisis." —Giancarlo Ibarguen, Executive President, Universidad Francisco Marroquin "At last, a book about the heart of capitalism as a force for creating good in the world for solving many of our tough societal problems. I hope our political leaders read it." —R. Edward Freeman, Olsson Professor of Business Administration, Academic Director, Business Roundtable Institute for Corporate Ethics, University of Virginia
