Short activity: Electrochemical Cell

In small groups the kids will be designing and assembling a water electrolysis device. In principle, the “device” uses electricity from a battery, to electrochemically separate water into its constituent components (hydrogen and oxygen). Each group of students will be supplied with a plastic, transparent cup, two electrode leads (insulated …
