Currents from the Kitchen
Our predictions were that a lemon would produce the most charge.
We couldn’t find a lemon so we did our experiment with a lime and it had great results.
We were able to generate 1-volt. The shorter the copper wire was the stronger voltage we got.
The strongest charge we managed to produce was 0.8v – 0.1v (v = volts).
Lab Requirements:
A Fruit or Vegetable
A Copper Wire
Zinc
2 Crocodile Wires
Volt Meter
Experiment done by (Boti and Jennifer).
Q1. What kind of circuit will produce electron flow in your fruit/vegetable cell?
A linear wire circuit using a fruit battery(lemon, copper, zinc).
Q2. If your bulb doesn’t glow, how can you find out if electrons are flowing?
Using a voltage meter, you can see the strength electricity in the measurement called volts.
Q3. If your bulb doesn’t glow, why not?
Because the voltage is not strong enough to power the light bulb.
Q4. How can we modify our experiment to improve our results?
Connecting more fruits to each other in a parallel system.
Q5. What is causing electrons to flow in this experiment?
The chemicals release electrons in the hopes that they will find protons.
Q6. How can I use this in my everyday life?
You could use it in emergency situations, but it wouldn’t be convenient in “everyday life”.
Q7. Is this the next “big thing” in clean energy?
No, this isn’t exactly useful in any way, for everyday use. It’s only useful for emergencies in my opinion.
Hello Boti and team,
I like how you observed the shorter the copper wire is, the higher the voltage you measured. Why do you think this is so?
In your response you mentioned that a parallel system would increase the effective voltage of your circuit, how can you test this out?
Well done,
Mr. Lim
