Each group should then pick a spokesperson to come to the front of the room and share the list of properties. This spokesperson should also show the rest of the class where the neighborhood is on the periodic table so that the other groups can see where they are in relation to that. Ask students if elements that are closer to each other have more similar or less similar properties than those farther away from each other. Guide students to see that elements are placed on the periodic table based on similar properties. Discuss the fact that elements are lined up in rows because they have similar properties within that row also.
Groups share more similar properties than do periods, however.
Have them show each other where they are on the periodic table. Each student should write directions for how to get to the other person's house. Extensions Have students write a story about their city from the point of view of their element. Have students come up with different analogies they could use to describe and map the periodic table. All students should be able to participate in this activity.
