In this activity, high voltage is applied across a pickle to emit a yellow glow. This activity should only be conducted by skilled adults and is best suited as a demonstration.

Learners build a simple one-cell battery and use an ammeter to measure the flow of current.

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 and demonstration about electricity and magnetism, learners observe how the current generated when one copper coil swings through a magnetic field starts a second coil swinging.
