Mrs. Franklin loves teaching science and thinks about it all the time. While walking one day, she steps on a warm, fresh piece of used gum. The gum flattens and sticks to her shoe. When she lifts her foot, she sees long strings of gum between her shoe and the sidewalk. She thinks, “What a great demonstration of the properties of metals!”What properties of metals would Mrs. Franklin most likely teach about with this demonstration?
