In this three-part lesson, students will learn the science behind Benjamin Franklin’s famous kite experiment and how he proved lightning and electricity to be the same. Students will consider the concept of “engineering for good” by analyzing the social and public health impacts of the invention of the lightning rod. Finally, students will conduct a quick investigation into a chemical substance known as graphene and take part in an engineering design challenge of their own, with the goal of emulating Franklin’s drive to engineer for public good.
