In this activity on page 4 of the PDF, explore the unique molecular structure and conductive nature of graphene. Learners construct a circuit with a battery and LED bulb. Then, they examine what happens when they touch two insulated wire leads attached to the circuit to pencil rubbings on paper. Learners compare what happens when they move the leads closer together and further apart. Use this activity to explore nanoscale science and nanotechnology.
