Have the students break up into design teams. Each can study the community with an eye for one of these things. Finally, you might want to offer a place for the kids to put up their maps.

History is full of ironies.
Take the automobile. When it was first introduced in the early 1900s, people thought it would make our environment cleaner and transportation easier. No more horse manure to step in, no more jam-packed streetcars. A hundred years later, we're choking on the smog produced by automobiles. Today, we sit in traffic jams on our way to suburbs that spread to the horizon.
