pennnnnny lab

Penny lab,

i found the penny lab to be extremly interresting. we took ourdinary copper pennies and made them silver then gold. we used some type of mixture and heated it up. then we placed the silver penny on a flame and it turned gold. following our lab, we were asked questions about the true matireal of the penny. i believe the panny did not change to gold, but it did change to a new color. all in all it was a wonderful expirience.

thank you,
