Lesson focuses on graphene and its electrical properties and applications. Students learn about nanotechnology and how engineers can harness the differences in how materials behave when small to address challenges in many industries. Students work in teams to hypothesize and then test whether graphene is an electrical conductor or insulator. They build a simple circuit using everyday items, and create a graphene sample using soft pencils on paper. They observe what they see, extrapolate to broader applications, present their ideas to the class, and reflect on the experience.

Anticipated Learner Outcomes
As a result of this activity, students should develop an understanding of:
- circuits, insulators, and conductors
Students explore nanotechnology and the material graphene in terms of its ability to conduct electricity and its impact on many industries and products. Students test graphene to see if it will be an insulator or conductor in a simple circuit, and develop hypothetical applications for graphene that would revolutionize a product or system. Teams present their ideas to the class and reflect on the experience.
