Current from the kitchen

Prediction:

The orange will produce the most electric voltage because it is very acidic which will have the effect of adding to the electric voltage.

 

Results:

The orange created the greatest electric voltage out of all the fruits and vegetables we experimented on.  The reason why fruits that are acidic gain more current electricity is because when a metal connects to any acidic material the electrons are given up by the atom. The acids benefit the battery in the circuit so the electrons flow nicely. The other fruits were very close in having the same reaction but the orange had more voltage by only a few segments. The apple had the least amount of electric voltage only by a few segments on the volt meter.

Observations:

First we did the experiment on the yam and attached copper and a nail and stuck them into the yam. We hooked the wires up so they were attached to the two variables. During this experiment we realized that the experiment worked best on the the fruits and vegetables that were the most acidic. We tested a yam, orange and an apple. For the yam and the apple the volt meter did not move as much as it did when we created a  circuit with the orange. The reason why fruits that are acidic gain more current electricity is because when a metal connects to any acidic material the electrons are given up by the atom.

 

 

Questions:

Q. a) If your bulb doesn’t glow, how can you find out if electrons are flowing?

b) If your bulb doesn’t glow, why not?

Q. How can we modify our experiment to improve our results?

Q. What is causing electrons to flow in this experiment?

 

 

Answers:

 

Ans. a) Even though the bulb will not light up, we noticed that the voltmeter  would move either forward or backwards showing that the electrons were flowing.

b) Th reason the bulb did not glow was because there are not enough electrons flowing for fruits and vegetables to turn on a light bulb.

Ans.  A way to modify the experiment is to add more acidic acids into the fruit to receive a better result.

Ans. The acids in the fruit and the chemicals in a battery are similar, most of the time the battery is the conductor in the circuit which causes the electrons to flow so the acidic acids in a fruit or vegetable causes the electrons to flow in this experiment.

 

Conclusion:

My prediction was correct, the orange produced the most electric voltage. I was not expecting how close all of the results would be but the orange did produce the most electric voltage. Our most important finding was the yam and the orange had similar results but the orange had one more segment on the volt meter than the yam. I found this experiment interesting because it showed me that the more acidic a fruit or vegetable is the more electric voltage there will be. If we were to do this experiment again I would like to answer my question of does the temperature of the fruit or vegetable effect the results shown on a volt meter?
