Currents from the Kitchen
-When we put the two metals on top of each fruit, we noticed that the deeper we dig those in, it gave a little bit more voltage than just touching the fruit’s surface.
-When we put an apple on top of the potato and connected the metals, the voltage increased to 0.4. If we had more time, we could’ve tried more fruits and see what happens.
-Our group also tried to squeeze lemon on top of lemon because lemon had more voltage, but apparently, it didn’t work because the apple’s voltage never increased and just remained as it is.
-We’ve also tried to light up the LED bulb with a potato, but it didn’t work, same as the other fruits. We also tried to use two fruits together, we saw a spark but when we tried it again, it never worked.
Apple and Potato: o.4
Lemon, mango, and potato have the most electric voltage. My hypothesis was supported. Why do citrus fruits (lemon) conduct more electricity than the other fruits?
How can I use this in my everyday life? If there’s a sudden power outage, I can use fruits to light up an LED bulb.
If your bulb doesn’t glow, why not? There are not enough electrons that are flowing (low voltage)
What is causing the electrons to flow in this experiment? the two metals (zinc and copper) that are placed on the fruit and the electrons will flow from the zinc metal to the copper wire through a connecting wire.
How can we modify our experiment to improve our results? We could’ve combined different fruits to try lighting up the LED light bulb.
