Best substances for cleaning pennies.

Materials: Pennies Coke Dish soap Vinegar A plate Pencil Paper Cup

Experimental Design
I am going to conduct my experiment in my kitchen in my house because it is a good place to do it and the counters are easy to clean. There will be two subjects of this experiment me and my pennies. I will need to conduct this experiment probably 5 times with each substance. I will record my data on a data table. I will make a document on my x-drive to hold all my data my table and pictures. Those are sine of the things that I will do in my experiment.

Materials and procedure.

Materials: Procedure: Step one:gather dirty pennies from couch, Pennies jars, ect. Step two: Choose a substance like coke. Coke Step three: Place a dirty pennies in the substance for Dish soap 50 minutes step four: take out the pennies with a clean Vinegar cloth and dry it, put it on a paper with the substance A plate Name above it.

 * **2. Information:** I learned from this source that I should clean a penny by putting it in a substance for a medium period of time like 20 or 30 minuets each. I learned that after you clean 20 or so pennies in the same substance you can put a nail in there for 15 minutes and the nail will get a copper coating. ||  ||

 * **3. Information:** from this source I learned that a penny is made from mostly zinc and a little copper because it is coated in copper. Penny used to be made in all copper in the 1800s but they stopped probably because it costed too much. ||  ||

===Conclusion: in the end there were two pennies that weren't clean in the end but all the pennies that did get cleaned got different ways. like the dish soap cleaned the pennies and left a rainbow like shine like oil in water. the vinegar and salt left the Pennie orange and clean but more like a matte orange. the coke is the only one that left the Pennie still shiny clean and looking like a real Pennie. but the hot sauce and water didn't do anything.===
