Your class is visiting the Statue of Liberty, and your first stop is the museum in its pedestal. one picture there shows a boatful of immigrants in 1907 - and one of the kids in the photo looks exactly like you! Suddenly the floor lurches strangely, and when you catch your breath you're standing on the deck of a huge ship in the middle of the ocean. It's 1907 and you're a passenger on your way to the United States!
