One thing I love about field trips is getting a chance to talk to the children a little bit more casually than usual. Bus rides, lunch time, and down time bring about some interesting conversations:
Today we passed a cemetery on our way to the field trip:
S: "Miss Prinzo...That's where all of the dead people live!"
Talking about TV:
J: L, you watch too much TV.
L: No I don't. I only watch a million hours a day.
