Results:

The lemon created the greatest electric voltage, and the carrot created the least amount of electric voltage.

Carrot – 0.12v

Banana – 0.23v

Lemon – 0.55v

Potato – 0.3v

Apple – 0.25v

Orange – 0.2v

Observations:

• The position of the metals/ alligator clips in the fruit and vegetables made a difference to how much velocity they had. When we wiggled and moved the metals/ alligator clips the velocity would increase and decrease

The fruits and vegetables were not very fresh; some of them had mold on them, and almost all of them were softWe put the metals/ alligator in already existing holes made from previous experiments

Conclusion Questions:

How can we modify our experiment to improve results?

To improve the results you could try creating a circuit with more than one of the same fruit or vegetable. For example you could make a circuit with three lemons in series to produce a greater voltage than the circuit we created with one lemon.

What is causing electrons to flow in this experiment?

The cords, alligator clips, and the specific metals stuck into the fruits and vegetables are causing electrons to flow in this experiment.

What kind of circuit will produce electron flow in your fruit/ vegetable cell?

A closed circuit will produce flow in the fruit/ vegetable cell. If the circuit is open there is a break in the electron flow, so they are not able to flow.
