"Which of five liquids cleans dirty pennies the most in one week? We will use very dirty pennies, less dirty pennies, and clean pennies in our experiment. "

"We believe that lime juice will work the best to clean pennies out of five liquids which are water, lime juice, orange juice, carrot juice, and vinegar because it has citric acid and is the most acidic. "

"We did not find what we expected in our hypothesis. We did guess correctly that the water would have no effect on the pennies. We thought that lime juice would clean pennies the best but instead it cleaned the pennies fourth best. It was odd that carrot juice cleaned better then lime juice because it had no acid. It may have been because there were different kinds of dirt on the carrot juice pennies than the lime juice pennies. The pennies in the carrot juice could have had soil on them while the ones in the lime juice could have been greatly tarnished."
