A few drops of dishwashing soap Paper towels Aluminum foil at least nine by 60 centimeters Scissors At least one lemon preferably with a thin skin Plate Knife and an adult's help when using it At least two plastic-coated paper clips Preparation Wash your pennies in soapy water, then rinse and dry them off with a paper towel. This will remove any dirt sticking to them. Carefully cut three aluminum foil rectangles, each three centimeters by 20 centimeters. Fold each strip in thirds lengthwise to get three sturdy one-centimeter-bycentimeter aluminum strips.
Physical Science Thank you for your input. When two dissimilar metals are placed in a common conducting solution,electricity will be produced. This is the basis of the electro-chemical cell, or wet cell. In the early nineteenth-century, Alessandro Volta used this fact of physics to invent the voltaic pile and discovered the first practical method of generating electricity.
Constructed of alternating discs of zinc and copper metals with pieces of cardboard soaked in a salt solution between the metals, his voltaic pile produced an electrical current. A wet cell consists of a negative electrode,a positive electrode and an electrolyte, which conducts ions atoms with an electric charge.
In this science fair project, copper and zinc metals will be used as the electrodes and the citric acid found in fresh fruit is the electrolyte. The chemistry behind the fruit cell is that zinc is more reactive than copper which means zinc loses electrons more easily than copper.
As a result, oxidation occurs inthe zinc metal strip and zinc metal loses electrons which thenbecome zinc ions. The electrons then flow from the zinc strip to the copper strip through an external circuit. In this project an LED is used to indicate if the fruit-cell is generating an electric current.
An electric current can flow only in one direction through LEDs, which means that they have a positive and negative terminal also referred to as the anode and cathode.
The cathode should be connected to the negative zinc metal strip, and the anode to the positive copper strip. The fruits used in this project should not be eaten. Care should be taken when handling the metal electrodes, LED and alligator clip leads.
