A Venn diagram is used to compare and contrast different topics. The items that are unique to each topic are represented in the separate sections of the circles, and the items that are common to both topics are represented in the center overlapping sections. Harlow creates this Venn diagram comparing and contrasting endothermic and exothermic processes. Two overlapping circles are labeled on the left endothermic and on the right exothermic. In the left circle are labels requires energy and examples. In the right circle are labels releases energy and examples. In the overlap is the label involve energy. What can be added to the Examples section of each circle? Endothermic: ice melting into water, and a heat pack becoming warm Exothermic: a glow stick glowing, and fireworks exploding Endothermic: ice melting into water, and an instant ice pack turning cold Exothermic: fireworks exploding, and gasoline burning Endothermic: a glow stick glowing, and a heat pack becoming warm Exothermic: an instant ice pack turning cold, and ice melting into water Endothermic: gasoline burning, and an instant ice pack turning cold Exothermic: ice melting into water, and an instant ice pack turning cold
