Consider Concept Map 1,1, which provides an overview of motion. Review Sections 1,2 and 1,3 and make a list of at least five additional concepts you could add to the map. Now consider where to place these concepts on the map. Keep in mind that general, more inclusive concepts go towards the top, whereas more specific ideas and examples go toward the bottom. Place your concepts on the map. Draw the possible connections between your five new concepts and the rest of the map. Remember to use "linking words'' to create propositions and to express your ideas clearly. When you've finished updating your map, compare your revised concept map with that of a classmate's. Are they identical? Would you expect them to be?
