  1. This was a well conducted experiment. I would encourage the researcher to think about a negative control, such as no coin or a wooden coin or plastic tab. Also, I would encourage the research to investigate if the pennies and quarters they used are really made out of copper and silver. If the pennies are new, they may not be made with copper. How would this change your experiment?

  2. Very nice experiment! I like how you discussed your experimental plan, explained the results, and provided a reason for your results in your conclusion.
