Imagine a classroom filled with teenagers sitting at their desks

Imagine a classroom filled with teenagers sitting at their desks.. Each one is turning their head backwards, It's as if they are looking at something happening behind them.. The room is well-lit., Large windows let in lots of natural light,. The walls are decorated with educational posters and a blackboard at the front.. The students are wearing casual clothes., and their expressions range from curiosity to surprise.. Some desks have school supplies scattered on them., which adds a touch of realism and dynamism to the scene..
