Look at the test results. The class tested 3 cups to keep ice water cold for 30 minutes. Cup A had no wrap and warmed from 32°F to 55°F, and the ice melted all the way. Cup B had newspaper and warmed to 40°F, with half the ice left. Cup C had bubble wrap and warmed to 34°F, with almost all the ice left. What should students change based on what the test showed?
