Step Back Science - Flick a Switch

by Anna Prokos

Introducing a whole new way to learn science! Start at the end and work backwards! You flick a light switch in your house and lights go on. But how did that happen? There are actually many steps that lead up to that final result. Many complex processes need to take place, and many components need to function properly. How does the light switch make the electricity flow? How does the electricity get into the house? How does it get into the neighborhood? Where is the electricity actually generated? Step Back Science answers these questions with detailed text, fun engaging sidebars, and great photos and graphics as it ties together elements from science, design, and engineering.
