I prepared a copper rod，two identical strips of white paper and matches to do this experiment.And the experimental procedures are below：First，light one of the slips by a match.Then，wrap another slip of paper tightly around the copper rod before lighting the paper.As a result，the first one burned quickly but the second one did not. After this experiment，I came to a conclusion that because copper has good thermal conductivity，the paper doesn't burn. $
