I could use some more ideas for field trips. I have three young men from Brazil and each Friday I try to take them somewhere both educational and fun. For example: Once we went to a foreign cars showroom and I used the opportunity to quiz them on car parts. The winner gets a prize. Another time we went shooting and they learned about small arms weaponry. They were quizzed on proper handling of weapons afterwards. We've done the zoo thing and animal quiz.

I have them for about two more months, any suggestions?
