Introduction The first, simple battery was created in 1799 by Alexander Volta. Today, batteries provide the power for a range of devices. Batteries generate electricity through a chemical reaction between two different electrodes and one electrolyte. An electrode is a conductor through which electricity enters or leaves an object, substance, or region. An electrolyte is a liquid that contains ions and can be decomposed by electrolysis. I chose this topic because I have an interest in making batteries out of things we use every day. I realised that I had all the basic materials to do this experiment and therefore performed this experiment. Research Question To what extent does the distance between two electrodes affect the voltage and amperage produced by a fruit battery when the fruit is at room temperature? Materials Required • Apple, lemon, kiwi, or other fruit at room temperature. • Digital multimeter • Alligator clip wires/test leads • Zinc plate, galvanized nail as the zinc electrode • Small Copper plate or shiny copper penny as the copper electrode • Thread and Ruler to measure the distance • A notebook to record the readings of the multimeter. Variables 1. Independent Variables: The electrolyte source (lemon, apple, kiwi) 2. Dependent Variables: The Voltage produced. 3. Controlled Variables: The same person must be performing the whole experiment. The same materials should be used to take every reading. 4. Standard of comparison: Test the leads together, they should not produce electricity. If they do, wipe them clean and try again. Hypothesis I hypothesize that there will be a negative relationship between electrode distance and voltage and amperage produced in which as the distance increases the voltage and amperage decrease. Exact quantitative predictions are currently not possible. Procedure 1. Firstly, I will carefully clean all the materials required ensuring that a
