The Penny Lab

In the Penny Lab, our group of people put our pennies into a hot dish filled with Zinc. We had to mix the Zinc and the pennies to make sure the pennies were covered in Zinc. Later, once we let the pennies sit, we realized that our pennies had turned silver. Then we held our pennies over fire and the penny started to turn gold. Over the fire the penny turned back to its regular copper color, but seconds after it turned into a gold color. I'm not too sure if we actually made real gold, but to find that out i think we would have to match the molecules of the "new penny" and see if they match the ones of gold, just to make sure. Overall the lad was interesting because i have never seen a penny turn gold before.
