A Battery That Makes Cents
Abstract
Many coins in the pile will make the most electricity. If there are more coins in the pile, then the more electricity it can produce, because the more electrons you have, the more electricity you will get. Batteries are expensive, but you can make one for exactly 24 cents! In this experiment, you will make your own voltaic pile using pennies and nickels. In the data, we will see if the number of pennies and nickels will affect the number of voltage and current.
Problem
How many coins in the pile will make the most electricity?
Hypothesis
If there are more coins, then the more electricity it can produce, because the more electrons you have the more electricity you will get.

Background/Research
You might think that batteries are a modern invention, but batteries were one of the first ways of making electricity. Alessandro Volta discovered the first electric battery in 1800. He made a giant stack of alternating layers of zinc, blotting paper soaked in salt water, and silver. This early design for a battery became known as the voltaic pile.
How does a voltaic pile make electricity? The key to electricity is the movement of electrons. In a voltaic pile, electrons move from one metal to the other through the saltwater solution. The saltwater solution is called an electrolyte, and it contains ions in solution from the dissolved salts. An ion is a group of atoms that carries a positive or negative electric charge. The ions react with the metals, causing an electrochemical reaction, a special kind of chemical reaction that makes electrons.
The two types of metals in a voltaic pile are called electrodes. Since there are two kinds of metals, one metal reacts more strongly than the other, which leaves an electrical potential difference, also called voltage, between the two types of
