This book shows early years carers how to help children discover the natural world through the magical experience of playing with light.

Entertaining and informative, the newly updated Britannica Student Encyclopedia helps children gain a better understanding of their world. Updated for 2012, more than 2,250 captivating articles cover everything from Barack Obama to video games. Children are sure to immerse themselves in 2,700 photos, charts, and tables that help explain concepts and subjects, as well as 1,200 maps and flags from across the globe. Britannica Student is curriculum correlated and a recent winner of the 2008 Teachers Choice Award and 2010 AEP Distinguished achievement award.

"Children are continually developing ideas and explanations about their natural world. … Some of these ideas are consistent with the science children are taught; others differ significantly from scientific explanations. Many of these ideas will follow students into adulthood if they remain hidden from the teacher and unresolved. The challenge for teachers is to find ways to elicit these ideas and then use appropriate strategies to move students’ learning forward.” —Page Keeley, author of the bestselling NSTA Press series Uncovering Student Ideas in Science You don’t have to become a mind reader to understand the ideas young students bring to science class. This collection will help you draw out and then recognize what students know—or think they know—about the natural world. What Are They Thinking? is a compendium of 30 “Formative Assessment Probes” columns from NSTA’s elementary journal Science and Children. Each chapter provides: • A sample formative assessment probe: a set of interesting questions that root out commonly held, often-mistaken ideas. Geared to elementary students, probe topics range from why you can see the Moon in the daytime to where water goes when it evaporates to what is or isn’t a rock. Your students’ answers to each probe will help you take a step back and figure out how to guide them from where they are conceptually to where they need to be. • Accompanying teacher notes: easy-to-grasp explanations and advice that tell you how to encourage evidence-based discussion and then monitor students’ understanding. • A bonus feature: a set of study group questions written especially for this compendium by award-winning author Page Keeley. So forget about acquiring psychic powers. Instead, turn to What Are They Thinking? to transform both your teaching and your students’ learning about science.

A user's manual for our everyday world! "Whether a curious layperson, a trained physicist, or a beginning physics student, most everyone will find this book an interesting and enlightening read and will go away comforted in that the world is not so strange and inexplicable after all." —From the Foreword by Carl Wieman, Nobel Laureate in Physics 2001, and CASE/Carnegie US University Professor of the Year 2004 If you didn't know better, you might think the world was filled with magic—from the household appliances that make our lives easier to the CDs and DVDs that fill our world with sounds and images. Even a simple light bulb can seem mysterious when you stop to think about it. Now in How Everything Works, Louis Bloomfield explains the physics behind the ordinary objects and natural phenomena all around us, and unravels the mysteries of how things work. Inside, you'll find easy-to-understand answers to scores of fascinating questions, including: How do microwave ovens cook food, and why does metal sometimes cause sparks in a microwave? How does an iPod use numbers to represent music? How do CDs and DVDs use light to convey information, and why are they so colorful? How can a CT or MRI image show a cross-sectional view of a person without actually entering the body? Why do golf balls have dimples? How does a pitcher make a curveball curve and knuckleball jitter about in an erratic manner? Why is the sun red at sunrise and sunset? How does a fluorescent lamp produce visible light? You don't need a science or engineering background to understand How Everything Works, all you need is an active curiosity about the extraordinary world all around you.
