In this electrochemistry activity, learners will explore two examples of electroplating.

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 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.
