Learners observe an electrochemical cell constructed from a small jar containing zinc and copper strips immersed in separate solutions. The strips are connected to a motor that turns a small fan.

Learners test solutions of water, sugar, salt, and hydrochloric acid for electrical conductivity. They immerse leads from a lighting device (a battery pack connected to an LED) into each solution.

In this demonstration, cook a cake using the heat produced when the cake batter conducts an electric current.

In this activity, learners investigate the properties of graphene and graphite.

This lesson focuses on graphene and its electrical properties and applications.
