The Revelatory Field Trip

This is just a one-shot, but it's fairly long.

Peter's class is going on a field trip to his own home: Stark Tower, home of Stark Industries and second home to the Avengers.

Peter's class doesn't even believe him about his internship with Tony Stark; they would never believe that Tony was actually his dad, as are Steve Rogers and Bucky Barnes.

Will the class discover Peter's parentage? Will they find out he's Spider-Man? (Spoiler: Yes, yes they will)

I know there are a lot of field trip fics, but I love them, and I tried to make mine as exciting as I could.
