The voltaic cell kit allows you to investigate the production of direct current electricity. It demonstrates the conversion of chemical energy into electrical energy. It may be used as a part of a science fair project. Copper and zinc electrodes are included. The science experimenter can use available materials to produce current such as iron nails and pieces of aluminum or even other metals or non-metals to show that some materials react to produce electricity and some do not.
The chemical industry was radically changed when direct current became available, largely through the efforts of Thomas Alva Edison, working in the late 1800s. An aspiring Science Fair contestant will want to read extensively, not only about Edison, but also about the changes to the chemical industry that occurred as a result of the new availability of direct current.
