Which fruit generates the most electricity?
Transcript of Which fruit generates the most electricity?
The First Steps
Alligator clip wires
1. Insert the zinc nail into the fruit
2. Insert the copper penny into the fruit.
*Keep the copper penny and zinc nail away from each other*
3. Set the multimeter to a voltage reading setting
4. Touch the black alligator clip wire to the zinc nail and the red alligator clip to the copper penny.
5. Check the multimeter to determine the fruit's electrical charge.
6. Record your findings.
7.Repeat these steps with the other fruits.
The lemon will generate the most electricity, because it is the most acidic.
During the experiment, Tiffany and I found it difficult to insert the penny into the fruit, especially the lime, lemon, and grapefruit, all which had thick skins. The zinc nail was easy to stick in since it had a pointy end. The multimeter also kept changing. For example, it would say 0.47, then change to 0.48, then 0.49, and then start the pattern over again. Eventually, it stopped on a number and that was what we recorded.
After performing the experiment, we found that
The lemon generates .8 volts
The grapefruit generates .51 volts
The lime generates .50 volts
The apples generates .45 volts
We found that the acidic fruits generated more electricity than the apple, a non-acidic fruit. All the data tells us acidic fruits generate more electricity.
What would we change?
We would use more fruits to have more accurate information.
We would use a shinier penny to see if it had a different affect.
We got our information from:
Lipper, Aurora.“Fruit Batteries Science Fair Project”. 2009. Viewed 6/15/13.
“How to Use a Multimeter to Test the Electric Charge in Fruits & Vegetables”. Viewed 6/15/13.
Bochinski, Julianne Blair. The complete handbook of science fair projects. New York: Wiley, 1991. Print.
Our hypothesis was acceptable. The lemon did generate the most electricity. The more acidic a fruit is, the more electricity it can generate. The lemon is the most acidic of all the fruits used. One of the new questions that my group member and I came up with was, why don't people use fruits to generate electricity instead of other fossil fuels?
