Purpose: Which fruit will produce the most electric voltage?
Hypothesis: When attaching the battery to a Orange or a Lemon, it will have the highest voltage amount.
Materials:
- 1 voltmeter
- 2 wires
- 1 nail
- 1 copper strip
- a orange
- a pickle
- a lemon
- knife
- zinc and copper
Procedure
- Cut the piece of fruit
- Put in 2 pieces of metal
- Attach to the voltmeter using wires
- record the results
- compare results from several pieces of fruit
Why? I feel that the citrus in the orange and lemon will produce some voltage.
Results
- Small Orange = .4 volts
- Big Orange = .3 volts
- Lemon = .5 volts then .8
- Pickle = .8
- Pear = .5 volts
- Potato = .5 volts

Conclusion
My hypothesis was wrong, the citrus fruits didn’t produce the biggest charge, the Pickle and Potato did. I really thought that the citrus would produce some sort electrical charge, but I was wrong.
Good post outlining the learning you gained from creating your own battery with fruit. Interesting what came out as the best electrolyte. Don’t forget to answer the lab questions. Could another variable that you may not have controlled so carefully have had an impact on your results?
