When we get sick, our doctors give us medicine. When we want to visit our grandparents across the country, we hop on a plane. And when we want something in our community to change, we vote for people who share our ideas. A lot of the things we have and do now began as strange or challenging ideas—or even accidents! Young readers will discover the history behind events that changed our world—and the people who made them possible. Photos and accessible text bring history to the forefront!
