In this electrochemistry activity, young learners and adult helpers create a battery from a potato to run a clock.

In this activity about chemistry and electricity, learners form a battery by placing their hands onto plates of different metals.

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

In this design challenge activity, learners design and build a circuit: an "electric highway" that connects a battery and buzzer at least three feet apart using four types of materials.

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.
