It was cold in my Chemistry class this morning, so the teacher lit all of the burners. IMMD.

i don’t think that’s a very efficient way to heat a room that big, and your teacher probably knows it. it’s more likely he just wanted to burn sh*t, in which case this made MY day.
Oh, yeah. Feel the (bunsen) burn!
My high school chem teacher did that once, too! It actually worked, I was impressed.
Bunsen burners remind me of the time I set the (supposedly non-combustible) tables on fire during a chemistry experiment.
So, did he get the “thank you” blowie the was hoping for?
Hopefully your environmental science teacher smacked him over the head with a Global Warming book.
…And then everyone passed out from carbon monoxide poisoning, no?
I thought this was a fairly standard way of warming up a cold laboratory classroom … but then maybe our local school just had very poor heating in that block.
Direct heating by methane combustion is actually a fairly efficient way of heating the place, so long as it’s not overly-ventilated. You avoid the loss found in most other methods, e.g. hot water centralised heating, and you’re only heating the one room rather than the whole building (AND a boilerhouse). And it’s far more efficient than electrical heat or ducted HVAC. It’s just not SAFE, is all
(the danger is kids setting themselves, objects, or the built environment on fire… carbon monoxide isn’t so much an issue if you use the smokeless blue flame… maybe if you overdo it, CO2 could be troublesome, but unless you’re in -10′c conditions or worse you’re unlikely to reach that point before the place is unbearably hot… the amount of cold air circulating in to keep the temperature down would by its very nature bring in more oxygen. Plus the fires would eventually reach a point where the remaining oxygen could no longer sustain them against the amount of methane rushing in and displacing the flame-front, and gutter out – hopefully before all the human occupants lost consciousness/died)
did he lit the goblet too?
Did he also bring marshmallows to make s’mores with?
our science teacher did that a few times, but had to turn them off cause some of the kids kept lighting bits of paper in them
