When my group did polishing pennies we put a pennies in each of the cups that were filled with different liquids. We waited 2 minutes
and then we looked to see if our pennies had shined. In the coke, it was a little bit shinny, in the detergent it still looked the same, in the vinegar the penny was still the same, but in the lemon juice the penny was so shinny I could hardly look at it.
My favourite station was probably polishing pennies but the other ones were fun too. What was your favourite station?
