Things To Do In Boston educational/fun for teens?

My class of about 25 8th graders is going on a school trip to Boston for a week in May. I was wondering what some things to do in Boston that are educational (the teachers will allow) but also fun and enjoyable for 12-14 year olds? Info and webistes would be great!
