In this activity, learners build a simple qualitative conductivity tester with a battery, bulb and foil.

In this activity, learners simulate the process of DNA fingerprinting by using electricity to separate colored dyes.

In this activity about electricity, learners explore what happens when you blow a fuse.

In this activity, learners construct a device out of a piezoelectric igniter, like those used as barbecue lighters.

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

In this activity, learners use their strength to light a light bulb. A chain made from paper clips is placed in series with a battery and flashlight bulb.

In this activity, learners build a simple electrolysis device. Then learners use an indicating solution to visualize hydrogen and oxygen molecules in water.

In this activity, learners create a tiny electric, motorized dancer. Learners use the interactions of magnetism and electric current to make a wire spin, while displaying the Lorentz Force in action.

In this activity, learners light an LED with five cents. Learners use two different metals and some sour, salty water to create a cheap battery.

In this activity, learners construct a simple electrolysis device. With this device, learners can decompose water into its elemental components: hydrogen and oxygen gas.
