When my daughter was 3 years old we took her to Liberty Science Center. As we got back into the car after a very long day she said "it was a great trip but a too long adventure". These words really describe my feelings today. I thoroughly enjoyed everything from the mapping activity and discussions of the forces changing the demography of the city to the story of the attentive mole but I really felt the need to do something.(Am I changing into my students?) As I was driving home today on West Chester Pike I thought of the trolley tracks of my childhood that once lined the middle of this road. They were gone with no traces remaining.In 50 years from now when our mole pops out again, what will our neighborhoods look like? Will technology be the driving force of place. Today our X-rays are read in Australia,manufactured goods come from China and our tech advise from India , where will the jobs be tomorrow? It is thought provoking to ponder about the forces that shape our place but as teachers isn't it even more important to  prepare our students to adapt to the changing landscape of their future.
