__**Abstract: **__ The purpose of this project is to determine what can be used in an emergency to power a light bulb if the connecting wire is broken. Multiple conductors were tested to see which one has the highest voltage and which is the best conductor. This project shows which of the five materials that is being tested is the best at conducting electricity. The battery sent electricity through each item and power a light bulb then the amount of electricity was measured to determine which one is the best conductor. The amount of electricity that is put into each object is the independent variable. The amount of electricity that gets through the object is the dependent variable. After the ones with the best conductivity were found the results are written down. The hypothesis that was made was supported because out of the 5 items which are aluminum foil, wood, a coin, paper, and copper wires the copper wires, coin, and aluminum foil conducted better than the other materials. Some materials did not conduct well like wood and a piece of paper but things like aluminum foil, a coin, and copper wires conducted well.

__**Question: **__ In an emergency situation like a broken electrical wire, what is the best alternative that can be used to conduct electricity?

The copper wires will conduct electricity better than all the other materials because the conductivity of the copper wires are better than the other materials.
 * __Hypothesis:__ **

__** Material **__ The material needed for testing conductivity were: Power Supply wires aluminum foil coin bulb wood copper wires paper __** Procedure: **__ 1 - The wire used to connect to the bulb is broken and then another piece of wire is used to connect the broken end. The voltage in that third piece of wire was measured and observed if the bulb turned on. 2 - The wire used to connect to the bulb is broken and then the two ends are connected to the coin. The voltage in the coin was measured and observed if the bulb turned on. 3 - The wire used to connect to the bulb is broken and then the two ends were connected to paper. The voltage in the paper was measured and observed if the bulb turned on.

4 - The wire used to connect to the bulb is broken and then the two ends were connected to wood. The voltage in the wood was measured and observed if the bulb turned on. 5 - The wire used to connect to the bulb is broken and then the two ends were connected with a piece of foil. The voltage in the foil was measured and observed if the bulb turned on. 6 - The wire used to connect to the bulb is broken and then the two ends were connected with a piece of paper. The voltage in the paper was measured and observed if the bulb turned on.

__** Results: **__
 * **//Tested Item//** || **//Voltage out//** || **//Voltage in//** ||
 * Copper Wire || 1.5 || .5 ||
 * paper || 1.5 || 0 ||
 * coin || 1.5 || .5 ||
 * wood || 1.5 || 0 ||
 * Aluminum foil || 1.5 || .5 ||

__**Conclusion:**__ Wire is not the only conductor of electricity. Although the tests shows that the cooper wire was a great conductor of electricity, it was not the only conductor. The voltage shows that foil and coin are also good conductors of electricity.
