Look at all of the globes and maps in the room. Find how the land and the water are shown. Can you see any islands, any peninsulas? A tiny dot may mean the whole city with hundreds of homes, factories and other buildings. Do you remember how we looked down on our town from a great height and saw the many houses? Just think of a tiny dot meaning all of our town.
