Five friends were looking at their shadows early one morning. They wondered what their shadows would look like by the end of the day. This is what they said: Jamal: “My shadow will keep getting longer throughout the day.” Morrie: “My shadow will keep getting shorter throughout the day.” Amy: “My shadow will keep getting longer until it reaches its longest point and then it will start getting shorter.” Fabian: “My shadow will keep getting shorter until noon and then it will start getting longer.” Penelope: “My shadow will stay about the same from morning to day’s end. Which friend do you most agree with? Describe your thinking. Explain the reason for your answer.
