One comment I heard over and over was how similar all of the students looked in the past. "Why'd they all dress the same? They look identical!" To prove a point, I took some pictures (below) which illustrate that modern students have the same tendency to look identical.
The point of the assignment, in conjunction with our Renaissance poetry unit (and slightly borrowed from Dead Poet's Society was to illustrate just how fleeting time can be. Just as the students in those yearbooks had the world ahead of them and are now much older, so will the current seniors soon be distant alumni. As the world freezes over tonight, take a moment yourself to freeze what you're doing and enjoy the moment. It won't come again.
