Hurumanu 5 | Lemon Batteries |

Aim: To produce an electrical current using lemons

Equipment: 

  • Lemon
  • Copper electrode
  • Zinc electrode
  • Copper wire
  • Voltmeter
Steps: 

  • Roll the lemon to release the juices inside.
  • Insert the copper about halfway through the lemon.
  • Do the same for the zinc.
  • Connect the wires into the voltmeter.
  • Then connect the wires into the copper and zinc plate. 
Findings: 

1 lemon = 1 volt
2 lemons = 1.8 volt
3 lemons = 2 volts

We also found that the volts can also change depending on where you place the copper and zinc plates onto the lemon.

  1. Hello Vann, I really like the experiment that you did in science. I like how you wrote the 3 result for your findings it really show me that your experiment work. What happen if you connect 4 lemons together will the volts still increase or decrease?, By the way you did a great job.
