“Juice” is a slang term sometimes used for electricity. Batteries are made up of one or more cells. Cells often consist of two different materials in a solution and connected to each other by a wire. In this experiment, you will study some basic principles of cells using the juice of a lemon as the cell solution. You will place small pieces of two different materials into the lemon, and a computer will be used to measure and display the voltages produced.
In this experiment, you will
Build several cells.
Measure and display cell voltages.
Discover which combinations produce a voltage.
Decide which combination makes the "best" battery.
