Fruit Electricity Experiment
Lesson Outline
We conducted an experiment on potatoes, apples, and lemons to test if they could conduct electricity. We learned that electric current is a flow of electrons and is measured in units called amperes or "amps." Voltage is the force that pushes the electrons through a circuit (like the pressure on water in a pipe) and is measured in volts. By placing a zinc coated nail and a copper nail in a conducting solution we formed the basis of an electrochemical cell, or wet cell. The chemistry behind the cell is that zinc is more reactive than copper which means zinc loses electrons more easily than copper. Next we constructed batteries from potatoes, apples, and lemons in series and tested them to see which one would produce the most electric current. We determined that 1 potato and 2 lemons can power an LED light or charge a cell phone in an emergency.
