The Conductivity of Metals Is there a metal that is a better conductor of electricity than Copper?

Intro- The price of copper is beginning to become a ridiculous amount, it is over 3 dollars for 1 pound! We wanted to find out if there was a metal that had a higher conductivity and solve a problem that the people of America are facing. Copper is a universal metal that is used in all of our electronic devices, and if we could find a metal that is a better conductor, than we can make is so that our electronics are cheaper and running better than ever! Most of the houses all over the world have an item inside of it that contains copper. It could be your light switch, a television, a hair dryer, any kitchen appliances, DVD players, and even the electrical wiring that is all over your house. The metals we are using in this experiment are Zinc, Lead, Aluminum, and Manganese. Our control group will be copper because it is the metal we are comparing all the results to. The voltage is going to be measured and the conductivity of the metals is the thing that will be measured. You don't have any reference to your works cited. Background research needs that. -- Andrew Gray Maybe talk about what makes copper so conductive and the properties needed to be conductive-Aaron Stachnik Why did you chose these metals is it because they are know to be pretty conductive?-Aaron Stachnik Hypothesis- If we test all of these metals with a 12 volt battery, then zinc will have the best conductivity out of the four metals, but copper will still be the best out of all of them. I feel like the hypothesis is odd. Maybe go one way or the other, saying "Zinc will have the best" or "Copper will have the best."? - Andrew Gray

What does your research tell you that makes you predict Zinc will be the best out of the alternatives that you are testing? Ms. Miller

Independent Variable: The voltage Dependent Variable: The electrical conductivity Controlled Variable: The Copper (is it the voltage or metal that is being changed? Stephen Vega) (For control variable you could connect the Ohm meter to the cables directly instead of going through a metal. Stephen Vega) Materials: 1. 1 pound of Copper 2. 1 pound of Zinc 3. 1 pound of Lead 4. 1 pound of Aluminum 5. 1 pound of Manganese Where can you purchase this? Ms. Miller 6. 1 pair of Jumper cables (I own a pair) 7. 1 12 volt battery (I own this as well) 8. 1 Ohm meter Total approximate cost: $22.04

Procedure: 1. Gather all of the materials 2. Put on safety glasses 3. Connect the Jumper cables to the 12 volt battery 4. Connect the Jumper cables to the piece of metal 5. Measure the electrical conductivity with the Ohm Meter 6. Record the Measurements 7. Repeat steps 4-6 until all data has been recorded 8. Move data onto a table 9. Publish the data

Be specific on the set up. Directions for using an ohm meter? What data are you collecting? Ms. Miller
