## How to Create a Potato Battery: 13 Steps (with Pictures)

Be sure to check the formatting, including capitalization, for the method you are using and update your citation, as needed. Objective In this experiment, you will make a simple battery out of coins and test if the number of coins in the pile will affect the amount of electricity produced. Label the battery voltage and the resistance light bulb. This article was co-authored by. This coin battery uses 4 pennies and 4 nickels. If it's not hooked up to a wire, it will theoretically last until the potato goes bad.

Literature a Foreign Two metals — an anode, which is the negative electrode, such as zinc, and a cathode, the positively charged electrode, such as copper. This sounds like more of a demonstration than an experiment. Retrieved November 2011, 2011, from Mini Science: Scott. The copper Cu atoms attract electrons more than the zinc Zn atoms. Make sure to include a legend on your graph so you know which is which.

Important: Double-check to make sure your multimeter is set to measure voltage, not current. An electrolyte is a liquid that contains particles carrying charge. Our classmates, who helped us whenever we are misguided and whenever we have difficulties. His control group was to add 15 ml of water to each group. So, basically I want to ind out will each different shoe yield different results of a crossover skill in basketball Thank you What are you actually measuring? You can purchase most of these materials at your local hardware or hobby store, or you may even have some of them at home already. In a science publication, you would choose between a table and a graph, but for the science fair project it is acceptable, and even encouraged, to showcase the data in both forms.

Notice how the zinc negative electrode of one potato is connected to the copper positive electrode of the next potato, with the green alligator clips. Attach the second clip lead to the galvanized nail in the second potato and the negative side of the battery box. The sign informs you about the direction of the current. To see if there are other trends in your data. Make a note of which way around the positive + and a negative - points of the battery went. If you need help making your display board, a downloadable display board template for this project is available for purchase below. Procedure We insert copper and zinc electrodes in to the potato, close but not touching each other.

First, as you probably discovered during your science project, a couple of potatoes can at best produce only a few milliamps of current. An example showing only one measurement is shown in Figure 9. Lynn This website is wonderful! Take an uncritical position, encourage wild ideas and discourage criticism of ideas. One place we can find electrical energy in our homes is at a wall outlet. They do not rot easily or attract pests to the same degree as fruits and other alternatives. It is used throughout millions- billions of homes throughout the world, to power so many things.

## Ask an Expert: Potato Battery

A battery works by providing electrons with a solution in which they can move around. This guide isn't setup like an experiment, so there is technically no independent variable. In the x axis can we put tube a ,tube b , tube c and tube d and in parenthesis 0 drops , 10 drops , 20 drops and 30 drops?. Dripping electrolyte can create a short circuit. The electrical current passing through the light bulb is enough to make it illuminate. Therefore, the more free ions a solution has, the better conductor it will be. Because they convert chemical energy into electrical energy.

## How Does a Potato Battery Work?

Attach one clip to the galvanized nail in the first potato and the other clip to the copper coin in the second potato. The exact distances you pick may depend on the size of your potatoes. Stevens holds a General Certificate of Education from Chelmsford College of Further Education. You now have all the materials to start building. If you need help creating graphs, try the. Record your answer in your lab notebook. Consider using a voltmeter or a multimeter for this.

Cite This Page General citation information is provided here. In a scientific experiment, the independent variable is the variable you manipulate to see what happens. If you are using a penny, make sure to press it into the potato so half of the penny is still visible above the surface of the potato skin so you can attach an alligator clip to it in the subsequent steps. You now have a stack containing 4 pennies and 4 nickels, like the stack shown in Figure 8. Russet Potato Throughout the experiment, I found that the russet potato was not as hard as the sweet potato, but I did have some difficultly getting the zinc and copper electrodes into the skin.
