An “escape game” activity is proposed to increase stimulation, team group skills, and adaptability in the chemistry classroom. The students follow in the footsteps of Nicolas Leblanc, a young French chemist, who took part in a contest launched by the French Academy of Sciences in 1775 to produce industrial soda ash. By means of scientific puzzles, such as using the periodic table, balancing a reaction, drawing up a flowsheet, or performing simple mole calculations, students will access combinations of numbers that allow them to open mechanisms present in the room that give them access to other enigmas. Following a precise sequence (controlled by the teacher present in the room), the students will thus advance in groups by retracing the development of one of the first industrial processes in the world. Escaping from the room is not the end of the activity: a debriefing will highlight the key elements of the construction of this process and will indicate the resources for further research, notably on the environmental consequences of the Leblanc process and the passing of the alkali act, one of the first laws to limit atmospheric pollution in the world. To simplify the principle of classical “escape games”, a classroom version, based on an easily printable paper sheet and locked file folders, is proposed in this paper.

逃生教室：Leblanc过程-一项教育性的“逃生游戏”

提议开展“逃避游戏”活动，以增加化学课堂的刺激性，团队能力和适应性。学生们跟随着年轻的法国化学家尼古拉斯·勒布朗（Nicolas Leblanc）的脚步，后者参加了法国科学院于1775年发起的生产工业纯碱的竞赛。通过科学难题，例如使用元素周期表，平衡反应，绘制流程图或执行简单的摩尔计算，学生将可以访问数字组合，从而使他们能够打开房间中存在的机制，从而使他们能够访问其他事物。谜团。按照精确的顺序（由教室里的老师控制），学生将通过追溯世界上最早的工业过程之一的发展而成群地前进。逃离房间并非活动的结局：汇报将突出此过程的关键要素，并将为进一步研究提供资源，特别是有关勒布朗氏过程对环境的影响以及碱行为的通过。 ，这是限制全球大气污染的首批法律之一。为了简化经典的“逃生游戏”的原理，本文提出了一种教室版本，该版本基于易于打印的纸张和锁定的文件夹。
