Problem What fruit makes the best battery?

__**Independent Variables**__
 * Weight of portion of fruit being tested
 * Distance alligator clips are apart
 * Volume of Juice

__**Dependent Variable**__
 * Acidity of fruits

Fruits:
 * __Materials__**
 * Multimeter
 * Popcorn Bowl
 * pH Measure Paper
 * Knife
 * Juice Squeezer
 * Alligator Clips
 * Two different pieces of metals: Copper and Aluminum
 * Saw
 * Wood
 * Metal cutter
 * Ruler
 * 50mL beaker
 * Clamp to hold metals
 * Orange
 * Lemon
 * Grapefruit
 * Lime
 * Apple
 * Tangerine
 * Pear
 * Banana


 * __Procedure__ **


 * 1) Slice each fruit into pieces of 50g each(keep sliced bits)
 * 2) Create a holder for the electrodes (different metals) so that they are always 1cm apard
 * 3) Stick electrodes in the fruit and measure the voltage and current of each fruit
 * 4) Repeat the experiment but squeeze each juice until you get 10ml of each juice(use your other sliced bits)


 * __Results__**
 * ~ Solid Form of Fruits ||~  ||~   ||
 * Fruits || Volts || Current ||
 * Orange || 0.57 || 0.11 ||
 * Tangerine || 0.54 || 0.06 ||
 * Lemon || 0.47 || 0.31 ||
 * Lime || 0.51 || 0.14 ||
 * Grapefruit || 0.52 || 0.11 ||
 * Pear || 0.52 || 0.06 ||
 * Banana || 0.59 || 0.27 ||
 * Apple || 0.58 || 0.05 ||
 * ~ Fruit Juice ||||~  ||~   ||
 * Fruits || Volts || Current || Weight (g) ||
 * Orange || 0.50 || 0.26 || 273.76 ||
 * Tangerine || 0.51 || 0.26 || 98.04 ||
 * Lemon || 0.55 || 0.87 || 121.15 ||
 * Lime || 0.51 || 0.13 || 93.07 ||
 * Grapefruit || 0.54 || 0.55 || 286.10 ||
 * Pear || 0.51 || 0.30 || 133.31 ||
 * Banana || 0.55 || 0.21 || 170.85 ||
 * Apple || 0.52 || 0.29 || 204.16 ||

Copper:this shows the amount of protons to newtrons in an atom Aluminum: this shows the amount of protons to newtrons in an atom pH Scale: This ilustrtates the acidity of some of these fruits and maybe perhaps determin which makes the best battery.

This shows how by connecting two fruits together, you can have enough power to power a clock.

These are examples of some citures fruits. The acids in these can be used to make a battery.
