The purpose of this experiment was to determine which of four citrus fruits (lemons, limes, oranges and grapefruits) can produce the most electricity. Electricity is measured in volts and volts are the electrical potential difference. Electricity is the motion of electrons through a conductor, which are materials like copper, silver, gold, and aluminum, that is protected by glass, plastic, rubber, air, and wood or insulators. One of the four citrus fruits had one penny inserted into the left side and a screw inserted into the right side of the fruit. The penny and the screw were both hooked up to the voltage meter. Out of the four fruits the lime had the highest voltage. The hypothesis said that the lemon was believed to have the highest voltage. This was unexpected because it appeared that the lemon would have the highest voltage because it is the most commonly used for fruit batteries. The lime had a voltage of 0.996 V. The hypothesis for the first experiment is that the lemon will conduct the most electricity. The hypothesis for the second experiment is that the lemon with two screws would have the highest voltage. The hypothesis for the third experiment is that the aura descent light bulbs would produce the most light. The hypothesis for the fourth experiment is that the regular light bulb would have the highest temperature at 120 sec.======

**CONCLUSION**
In the results for the first experiment, the lime was the fruit with the highest voltage. In the second and third experiments, the lemon with two screws had the highest voltage and the regular bulb let off the most light. In the fourth experiment, the regular light bulb had the highest temperature at the end of the experiment. The results of this experiment can benefit the world because when light bulbs are being designed, the light bulbs might be made from different materials similar to the coolest light bulb so the light bulbs will not increase in temperature so quickly. In the first and third experiments, the hypothesis was not correct. It was predicted that in the first experiment the lemon would have the highest voltage of all the citrus fruits. In the third experiment it was predicted that the energy saver light bulbs would produce the most light. In the second and fourth experiments the hypothesis was correct. It was predicted that in the second experiment the lemon with two screws would have the highest voltage. In the fourth experiment it was predicted that the light bulb would be the hottest at 120 sec. A follow up experiment that could have been performed to answer the question: Does the temperature of a light bulb before turned on effect the amount left off by the light bulb? The experiment could be improved by not only testing fruits but vegetables in the experiment. Another improvement would be to use LED (light emitting diodes) as a comparison to the standard light bulbs.
