This activity introduces students to the concept of building a galvanic cell and generating a cell potential (or voltage) from a battery of galvanic cells connected in series. The galvanic cell used involves two readily accessible metals and an easily prepared electrolytic solution. Assembling several galvanic cells in series makes a battery.
