| 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. We are
wondering if fruits and fruit juices can be used as electrolytes to make
batteries.

Project
description:
In this project you will perform experiments to make electricity from a
variety of chemicals and fruits. As a part of your research, you may
also compare the electrical voltage that can be made with different
fruits. What do you think? Can you get more electricity from lemon or
potato?
This project is also known as potato
battery.
