PURPOSE
The purpose of this experiment was to determine which type of citrus fruit produced the most electricity when used in a galvanic cell.
I became interested in this topic when I heard about our country's electricity shortage.
Astronauts and poor countries with an abundance of fruit but a lack of electricity could use the information gained from this experiment

HYPOTHESIS
My hypothesis was that the fruit with the most pH (most acidic) would create the most electricity.
I base my hypothesis on scientists that say electricity travels well through acidic substances and things that contain acids.

EXPERIMENT DESIGN
The constants in this study were:
• The size of the fruit (10cm).
• The type of metals (Iron and copper).
• The room temperature (21 C).
• The temperature of the fruit (21 C).
• The length of time measuring electricity (1 hour).
• The number of tests done on each fruit (5).
The manipulated variable was the types of fruit tested (grapefruit, lemon, lime, oranges).
The responding variable was the amount of electrical milli-volts a citrus fruit would create.
