Purpose: Which fruit will produce the most electric voltage.

Hypothesis: I think that the lemon will produce the most charge because the are famously known for having a good electrical current.

Materials: 1 voltmeter, 2 wires, 1 nail, 1 copper strip, at least three fruits/vegetables.

Procedure: put down your fruit stick your copper and your nail in hook up your wires to the voltmeter and boom.

Reasoning: My reason for choosing a lemon is because I think the juice will be very conductive.

Results

Potato: 5 volts

Lemon: 3 volts

Pear: 3 volts

Explanation

Using the copper and the galvanized nail along with wires and fruit we made an electrical circuit. Imagine the copper had a negative charge and the nail had a positive one then connect positive to negative to make the circuit. you need to make sure your copper and nail are firmly planted in your fruit.
