Air Battery

Make Electricity from Saltwater and Oxygen
Introduction:

Chemical energy stored in different substances can be converted to electrical energy. This ability is the foundation of design of all batteries.  

Each battery has two poles usually made of two different metals. One pole is the positive pole and the other is the negative pole. Electrons can travel from negative pole to the positive pole via a conductor such as a wire.
 A flow of electrons in a conductor is called electricity and if large enough, it can be used to make electro magnet, light up a light bulb or run an electric motor. Inside each battery there are chemicals that cause such chemical reactions. These chemicals in general are called electrolytes. 
 
 Project description:
In this project you will make a salt water battery and then perform a series of experiments to determine how does the amount of oxygen affect the life and the power of the battery.
