1. Big question -
Which fruit and vegetable conducts the most electricity ?

2. Hypothesis -
Fruits - a green apple because it is round, acidic and fat.
Vegetable - a lemon because it is sour and has lots of acid in it .

3. Interesting facts A lemon can only produce about only one milliamp.
A tingle felt on your tongue is due to the movements of electrons.
If you connect two lemons it can power a expensive watch.
Electrons are collected at one side and lost at the same time .
A lemon battery is called a voltaic battery.

4. Experiment - Materials – Lemons Green apple One galvanized nail
Penny/Copper wire
Four alligator clips
A holiday light that has a five centimeter light connected.

5. Detailed step by step instructions for vegetable -
First take a lemon and roll it gently on a table to get its inside mashed up without breaking its skin
Then take a galvanized nail and a penny or copper wire and stick it into the lemon .
After that remove the insulation from the holiday light .
Finally wrap the wire around the nail and penny or copper wire and use alligator clips to keep it on.

7. Step by step instructions for fruit -
First take a green apple and roll it gently on a table to get its inside mashed up without breaking its skin
Then take a galvanized nail and a penny or copper wire and stick it into the green apple .
After that remove the insulation from the holiday light .
Finally wrap the wire around the nail and penny or copper wire and use alligator clips to keep it on.
I repeated the experiment using orange instead of apple.

8. Control/variables -
I would like to add a multimeter and measure the volt of a lemon, grapefruit and orange and then try to light the light bulb .
I would also like to take out the green apple because it does not have enough juice to conduct electricity .

9. Observations -
When I used one lemon I could fell a light tingling sensation but with two lemons it was a little stronger . When I used the three lemons the light lighted up a little.

10. Data -
With one lemon the light bulb would not light up but I could feel a tingling sensation.
With two lemons light still did not light up but could feel electrons on my tongue .
With one green apple the light bulb would not light up but I could feel a tingling sensation.

11. Analysis of data -
Both a green apple and lemon did not conduct electricity required to light up a small bulb.
The apple did not produce enough electrons as they were escaping.
The lemon did not have enough current to power a bulb.

12. Conclusion - My hypothesis was correct to think that
A lemon conducts electricity
A green apple does not conduct electricity
An orange also conducts electricity
