In Annapolis, Md., young men and women in crisp white uniforms and white masks are doing what students here have been doing for 175 years — taking their first steps to becoming officers in the U.S. Navy.

These exercises are a part of the traditional "plebe summer," an intensive crash course that prepares first-year students for the transition to military life. They learn how to salute and march as a unit, along with lots of new lingo: floors are called "decks," toilets are "heads," and the students are "midshipmen."

Peaceful, student-led protests have been a powerful force for change throughout American history.

In 1925, for example, students at Fisk University staged a 10-week protest to speak out against the school's president, who didn't want students starting a chapter of the N.A.A.C.P. In 1940, almost 2,000 students protested after New York University decided to pull a black player from its football roster to accommodate the University of Missouri's segregationists.

And campus-based protests, including against racism, were a major lever of social change in the 1960s.

First, the end:

"Please be kind to one another. That's all for today."

Spring semester was off to a pretty normal start at Rolling Meadows High School. The school, in a northwest suburb of Chicago, was gearing up for the goodbye rituals of every spring semester: senior prom, end-of-year exams and graduation.

Caitlyn Walsh, the school's music teacher, was looking forward to the big choir concert and the spring musical. "From the fine arts scene we have a lot of end-of-year activities that are very cherished," she says.
