Most of what goes on in the universe—from exploding stars and biological growth to the operation of machines and the motion of people—involves energy being transformed from one form into other forms.

The Electric and Magnetic Forces Interactive E-book* uses everyday events and items, like lightning, flashlights, batteries, compasses, and maglev trains, to examine electricity and magnetism. It provides detailed explanations of key science concepts, plus self-directed, embedded assessment to allow readers to check their learning. Teaching strategies will help teachers better understand student preconceptions and inquiry learning. The book's appealing multimedia and interactive simulations can also be used in the classroom.
