Purpose: Which fruit will produce the most electric voltage?
Hypothesis: I think the more citric the fruit/vegetable the more electric voltage there will be.
Materials: one voltmeter 2 wires one nail 1 copper strip at least 3 fruits/ vegetables
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 fruits
Reasoning: To see which one will produce the most electric voltage.
Results:
Lemon: 0.75 V
Kiwi: 0.75 V
Apple: 0.5 V
Orange: 0.5 V
Strawberry: 0.75 V
Conclusion:
The fruit all ended up coming out with under 1 voltage of electricity. My hypothesis was right because the lemon and the strawberry had the most voltage and the lemon is very citric the strawberry probably had some citric in it because it was a couple of days old now but I thought that the orange would work like the lemon because they are both citrus so by hypothesis wasn’t completely right.
Questions:
1. What is causing electrons to flow in this experiment
The metal and the wires are what guide the electrons to the voltage meter.
2. what are the independent, dependent, and controlled variables in this experiment?
The independent variable was the fruit the dependent variable was the voltage of the fruit and the controlled variable was The wire the nail or the copper.
3. How can we modify our experiment to improve our results?
Maybe if we did multiple wires connected to one fruit then there will be more voltage.
4. what could be the sources of error or uncertainty in our experiment?
The fruit actually produces voltage.
5. How can I use this in my everyday life?
When I’m in the kitchen going to grab some strawberries so eat I can think about how out of most of the fruit it had the highest voltage.
