To create a potato battery, start by inserting a galvanized nail near the middle of the potato and pushing it in until it's almost to the other side. Next, insert a copper coin halfway into the potato about 1 in (2.5 cm) away from the nail. Make sure the nail and coin aren't touching each other! Then, using the end clips of a voltmeter, attach one clip to the nail and the other to the penn...
By virtue of the phosphoric acid and dissolved salts it contains, a potato can conduct electricity. When you insert a positive electrode made of copper and a negative electrode made of zinc, a charge will collect, and if you connect the electrodes of your potato battery, you'll detect a voltage.
How to Make a Potato Battery. Making a clock run on potato power is easier that you might think. This project is easy, bizarre and makes a sweet science fair project or chemistry experiment.
Potato battery works in a similar way. Zinc nail is an anode (has a surplus of electrons), the Copper nail is a cathode (attracts electrons) and potato is an electrolyte. When we put zinc nail in the potato, a chemical reaction occurs and it produces a surplus of electrons.
The potato itself acts a buffer between the copper and zinc during electron transfers. Learning About Electricity. The potato battery experiment provides an excellent way for kids (and adults) to learn more about science. Now that you've made a potato battery, you know more about how a circuit and electricity works.
A potato battery project is the last in a series of fruit and veggie battery projects included on this site. Many versions are available, but unless you want to get fancy with the voltmeter, fruit batteries make great science projects for kids since they are both inexpensive and relatively easy to perform.
Potato battery science project: Investigate how to make batteries out of potatoes using zinc and copper electrodes, connect them in series and in parallel, and use them to power a buzzer and LED.

Well, don’t be. The omnipresent potato, which is also called the king of vegetables, is an electrochemical cell. This simply means that it can produce electricity using the chemicals found in it. Let’s make a potato battery to see for ourselves. Materials Required. You will need the following materials to make a potato battery.
Make a potato battery and light up a bulb? That doesn’t sound right. But yes, you can do it. In fact, the potato battery experiment is a Science project that is used by many schools to teach kids about electricity. If you don’t have a potato in the house, lemons are good alternatives.
