That sounds genuinely shocking to me, in what country? Do you not have supervisors for the high school students? At uni you shouldn’t need much supervision, but for teenagers that’s mandatory.
This was at a community college in the US. Instructors are supposed to be supervising them with lab coordinators supporting them. The lab that had the gas incident was downstairs and the student was left unattended or otherwise gained access to the lab after class. Hence the instructor’s supervisor had a chat with them about not doing that. The biology lab coordinator responsible for those labs found the gas was on and had to shut off the gas.
As for the broken glass, theyd break something then throw it in the dirty glassware bin hoping no one would find out. Which is sad because students shouldnt be afraid of it being found out that they broke glassware on accident. Almost everyone breaks glassware on accident eventually. I just want that broken glassware to be dealt with correctly so I dont find out what they did when dealing with the dirty glassware after class.
