What I find happens with my kiddos, year after year, is that interest starts out strong and then slowly wanes throughout the day until there is nothing left. By the time we get to the 5th building, the realization that all they will get to do is walk, look, and be talked at sinks in. Their brain is in overload. Too much information, but no way to make it stick.
I question whether this field trip is developmentally appropriate for them. If I can't remember much from it, how much do they retain? It's difficult to experience joyful learning when you are sitting on your hands. How can I make it more engaging? I need some ideas.
