Can fruit produce electricity?

i am helping my daughter with her science fair project. she is doing a project that see if fruit can produce electricity. i need help on try to find out what electricity is and what fruit produces the most electricity. i have been on many site but i didn't find anything useful. soo if any body out there done this experiment before please help me. thank you

Can fruit produce electricity?
Get a volt meter, a few different fruits and a few different kinds of metal.



Electricity is made by an acid (Lemons or other fruit) and two different kinds of metal. In the acid of the fruit electrons flow from one metal to the other. The different metals paired together with each other are better than others.



Attach a wire to the metals (pennies, nails etc) and put them into the fruit and see how much the volt meter moves. You can show how one pair of metals may be beter than another or one fruit is beter than others (oranges vs lemons vs potato etc).
Reply:I use an OLD penny stuck in one side of a lemon and zinc-coated nail stuck in the other end. Connect a volt meter set on single-digit volts to show how much elect. is flowing. A small amt. of elect will flow from the nail to the penny. Try it with an orange and a kiwi and the famous potato. each one will be different. Have fun with your daughter, I can't wait until mine is old enough to do stuff like this with!

Fruit can make electricity!?



I. Purpose

The purpose of this activity is to find out if electricity can be made from some fruits.



II. Hypothesis

Fruits can generate electricity



III. Procedure

A. Research

Electricity

Is one type of energy or power. The electricity in one form or another is all around us. For example, our bodies and other living things have electricity in them. By controlling the electricity around us, by making it work for us, we have changed the world.



Pioneers in Electricity

In 1752 Benjamin Franklin used a kite to prove that lighting was electricity. Thomas Edison invented the first successful electric light bulb and the first electrical power distribution company.



Making Electricity

People make electricity at electric power stations. Machines called generator make electricity from other forms of energy such as coal, falling water, wind, gas, oil or atomic energy. Wires or conductor are the ones that carry or conduct the electrical current.



Using Electricity

We use the energy of electricity in our homes, schools, businesses, hospitals, etc.



Electricity has helped bring the countries of the world closer by speeding up and improving communication. Our telephones, televisions, and other communications instruments all run on electricity.



B. Experiment

Materials:



3 copper wires



3 copper strips



3 zinc strips



3 limes



3 oranges



3 apples



Multi tester or battery tester.



Procedure

Get the 3 limes on flat surface, on each lime stick a copper strip and a zinc strip on opposite sides. Connect a copper wire to the copper strip of the first lime to the zinc strip of the second lime; then, connect a second copper wire to the copper strip of the second lime to the zinc strip of the third lime. Connect another wire to the copper strip of the third lime to the red lead of the tester of the third lime, and connect a wire to the zinc strip of the first lime to the black lead of the tester. Watch the needle move in the tester battery tester. Repeat the same procedure with apples, bananas, and one of each fruit.



IV. Observations and Results

What happen when we connect the limes to the battery tester? The needle on the battery tester jumped, that shows limes can generate a small amount of electricity.



What happen when we connect the apples to the battery tester? The needle on the battery tester jumped, that shows apples can generate a small amount of electricity.



What happen when we connect the bananas to the battery tester? The needle on the battery tester jumped, that shows bananas can generate a small amount of electricity.



What happen when we connect a banana, a lime and an apple to the battery tester? The needle on the battery tester jumped, that shows bananas can generate a small amount of electricity.



V. Conclusion

We can generate only a small amount of electricity from fruits.



In this experiment I used apples, bananas, and limes to produce electricity.

Reply:A lemon is what you need.
Reply:Yes it can.

Potatoes are famous for that but most fruit can produce electrical current to some degree.

Here is a link if you want to build a project.

Or the clock powered by a potato.

I'm sure that you can find others just Google "Potato Battery"
Reply:citrus fruit can, as the lemon battery was the first source of DC (direct current) batteries.
Reply:my daughter used a potato in hers and charged a light...

you might try that...
