Observation Of The Circuit Setup :
I noticed that all parts of the circuit has to be closed in order for the lightbulb to light up . It took my group awhile to figure out how the circuit was set up.
orange= 3 v ( volts)
apple = 2 v ( volts )
grape = 5v ( volts )
lemon = 7v (volts)
Observations/ End Result :
In conclusion i think my prediction was correct ! The more acidic foods the more they’ll conduct electricity . The acid in the fruits make ions / charged particles , when put in a solution with water ,witch lemons have much water in them .The ions from the acids are the same type as the ions in a electric current .
