If you mean an explanation of what a scene could look like, then here:
A lot of kids bustling about, carrying armfuls of loose-leaf paper, textbooks, and other random things. They're chatting while walking to the trash cans set up outside in the hallways for easy access. The teacher scolds someone for running in the hall with a pair of scissors in their hand, as it is very dangerous. Students grabbing fistfuls of trash and paper out of their lockers, hurrying to quickly clean, before it was time for the next class. Their bustling causes them to nearly collide with other students, they're scrambling for papers that drifted off their stacks.
Hope that helps, sorry if that's not what you wanted.
