Observations:

-When we switched the metals, the charge went from positive to negative.

-The location of the metals and how deep they were changed the strength of the charge.

-The more acidic fruits made a higher charge.

Questions:

How can we modify our experiment to improve our results?

We can adjust and reposition the metal or push it deeper to change the strength of the charge.

How can I use this in my everyday life?

In an emergency situation, you could use this to get power to devices that need it.

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

A complete/full circuit with both metals inside of the fruit and plugged into the voltage detector.
