what fruit has the most energy, and how much.

Our hypothesis is that fruits well be able to power a basic circuit, and the more sour the fruit the greater energy source.
if a fruit has a signifacent diffrence from the others
then we will find out why it has so much more energy
because we could find somthing really cool on why it has so much voltage.
how do fruits have energy in them, what is copper, what is zinc, what is a voltmeter, how energy flows through wires.
independent: fruit (lemon, orange, apple, grapefruit, and tomato)
1. cut fruits in half and insert copper and zinc
2. use voltmeter on the copper and zinc to find out how much voltage the fruit has
3. record our observatoins in a google sheet
4. transfer our information we gathered to the cysf website
orange: size does not effect the power because its the acitidy that makes the bigger difference march, 8 2021
lemon: roll the lemon to get more energy out of them march, 8 2021
apple: it makes it easier the hard the fruit because it well hold the copper, zinc in better march, 8 2021
grapefruit: it does not mader where you put the probs on the electods they will get the same reading march, 8 2021
tamato: no observation march, 8 2021
during our experiment we found out that the size of the fruit does not matter and the thing that makes a difference in the amount of voltage it has is the acidity. also we found out that we can just guess the amount of voltage by finding an average for that fruit. in our experiment we did three tests for how much voltage on each fruit. we did three different fruit for the tests so we new that the fruit didn't stand out from the others. so in total we did 45 tests.
It was suprising when we saw the resultes because we thought it was going to be the lemon with the most energy
hight for apple: 975
low for apple: 919
average for apple: 933
hight for lemon: 889
low for lemon: 800
average for lemon: 871
hight for tomato: 865
low for tomato: 845
average for tomato: 865
hight for grapefruit: 847
low for grapefruit: 847
average for grapefruit: 769
hight for ogrange: 901
low for orange: 858
average for orange: 901
so the fruit with the most energy was an apple. and the fruit with the least energy was a grapefruit
you could use it to power a circut well you run to the store to buy a new battery. you could even only use them for small things because after you do this to a fruit it will mostly taste the same.
this could be aplied to so many basic circiuts though.
Sources Of Error
when we were doing the project we ran into trouble when we cut the fruits in half because when we inserted the copper and zinc the electrodes moved around a lot. we also tested how long the fruits last but it goes out with out keeping track of the time so you have to go with what it was the last time you saw it so we stoped doing that and also we needed three test for every fruit and they were taking around 30min which would of taken forever because we did 45 tests.
We used a video (https://courses.lumenlearning.com/boundless-physics/chapter/voltmeters-and-ammeters/) to help us understand the basics of how a voltmeter works. we also used a video (https://www.youtube.com/watch?v=GhbuhT1GDpI) to help us with knowing how to build the circuit.
