It’s always great seeing what creative ideas kids come up with when challenged to solve complex issues. Popular Science Editor-in-chief Mark Jannot challenged a class of 5th graders to “change the world.” Their response – a collection of short essays and sketches – shows unique and inventive creativity that is so great in young imaginative minds. Some great ones include living in space for part of the year to reduce energy consumption on the Earth (pictured), using salt from ocean water as a fuel source, and using polymer body panels on cars so that they “bounce” off each other in a collision. Maybe we should invite kids to our future brainstorm sessions…?
