2 total works
This practical book answers common questions about electricity by looking at evidence and demonstrating its properties through a range of carefully chosen experiments that can be done in the classroom or at home. It covers such questions as 'What is electricity?', 'How does electricity make things glow?', 'How do we measure electrical charge?'. 'How do we make an electrical current?' and 'How are electricity and magnetism linked?' It also includes questions for readers to investigate further on their own. Written by a highly experienced and acclaimed science writer, the book includes links to useful websites as well as glossary, index and list of further reading.
Early in the 17th century, Francis Bacon decided that the best way to learn about the world was to discover things for oneself. Since then, science has been a marriage of observation and experimentation. The experiments contained in each chapter allow young scientists to investigate basic principles using common household materials and easy-to-follow instructions. The titles are filled with dozens of color photographs that illustrate experiments and provide a glimpse of everyday and extraordinary uses of the subject. In addition, engaging features such as "Did You Know?" boxes provide fascinating facts. The "In Focus" sections offer in-depth looks at specific features of each subject. "In The Real World" boxes highlight pivotal experiments by real scientists.
