Go sing Christmas carols to different people.
Practice with your youth group for 2 to 3 weeks before you are going to go out caroling. Compile a list of people in your church that are shutins\in a hospital\elderly\in a nursing home\etc. After you have compiled your list of names and addresses, bring the teens to the house and sing to the folks. It is a pretty simple activity yet the people that you do it for will love the caroling and the teens singing will have a wonderful time.
