Currents from the Kitchen

Prediction: My prediction is that a lemon will have the greatest electric voltage.

Why: The lemon will have the most power because it has the most acidic properties. The electrons flow through the acid well and are able to create the voltage easily.img_1647

Observations:

When the grape was laying down on its side the volt charge went down.

We had to have one cord on the red plug and the other on the 3V.img_1646

Results:

Grape: The grape had a 2.5 volt charge

Apple: The apple had a 1.5 volt charge.

Lemon: The lemon had a 3 volt charge

My prediction was supported with the lemon having the greatest voltage charge.

Questions:

  • What kind of circuit will produce electron flow in your fruit/vegetable cell?  A series circuit
  • If your bulb doesn’t glow, how can you find out if electrons are flowing?   Look at the voltage meter to see if it has moved.
  • If your bulb doesn’t glow, why not?  There could not be enough electrons flowing.
  • How can we modify our experiment to improve our results?  Use more fruits with more acidic properties.
  • What is causing electrons to flow in this experiment? The electrolytes and acid
  • How can I use this in my everyday life? You can make a temporary battery.
