Electricity is all around us: cars, telephones, computers, lights -- the modern world runs entirely on electrons. But what are electrons? How do they behave? How do we control them? This book will show you how to build a battery, detect static electricity and construct a basic current meter, all using common items from your kitchen. Along the way you'll learn about the meaning of "voltage" and "current," what makes an LED work and the difference between AC and DC. The last chapter uses transistors -- the basic building blocks of every computer -- for lots of interesting experiments. With plenty of colorful illustrations, historical stories and an easy, accessible style, "A Kitchen Course in Electricity and Magnetism" will be a great start for budding and amateur scientists who want to learn more about how the world works.

This fascinating book examines theories of children's perceptions of space and place and explores how these theories are applied to the world of children. The focus is on children in large real world spaces; places that children live in, explore and learn from. These include classrooms, playgrounds, homes and yards, towns, communities, countryside, natural environments, and the wider world. An international team of authors compare the experiences of children from different cultures and backgrounds. Often excluded from discussions of place-design on the presumption of lack of awareness, young children have many environmental competencies which should lead to their inclusion. They can read maps and study photographs, respond to the natural and man-made world with great sensitivity, and contribute considerably to the community. This book will appeal to environmental and developmental psychologists and geographers, and also to planners by linking research on children's understandings and on their daily lives to recommendations for practice.
