Experiment 2
Batteries: Can a series of homemade electric cells form a "pile" strong enough to match the voltage of a D-cell battery?

Purpose/Hypothesis

In this experiment, you will construct a cell from copper and zinc electrodes and a lemon. The lemon contains citric acid, which is a weak electrolyte. After measuring the voltage of that one cell, you will add more cells to the pile to attempt to match the voltage of a D-cell battery. Before you begin, make an educated guess about the outcome of this experiment based on your knowledge of batteries. This educated guess, or prediction, is your hypothesisAn idea in the form of a statement that can be tested by observation and/or experiment.. A hypothesis should explain these things:

• the...
