Well ? No not really !
What can kill you more than a budget that removes more teachers from the staffroom? What is more disheartening than a bunch of 2nd years that dont care about making O2 or CO2, lighting a splint with a lighter, extinguishing it in CO2 & relighting it in a Jar of O2.
A photocopier that doesn't do what it says on the tin. I do not know how many teaching hours & efforts have been lost because the photocopier/printer in the workroom does not just damn well print. In fact you must go and click on an option on the print page. You must do that on every machine that you want to ever damn well print from, arrrrrggggghhhhh!!!
Said it to the office, deep inhale, maybe ?
Like I said made O2 & CO2 with Hone, bit more gases to make with the other 2nd years .... must drain the hydrogen oxide from the flask ....

Well it is a job in education, and thus an educational job.
Today a student in Physics class asked me as they began to draw the domestic circuit as to why there was a neutral wire, what was the point. I began to explain that electricity needed a circuit to flow, and that an alternating current went one way and then the other. (electrons flow one way and then do flow the other way) but the reason that there was no need for a fuse on the Neutral wire was eluding me.
So I got home and jigged a bit, then googled some more. Its not the fact that the neutral wire is at a grounded potential (not a grounding wire) that was the moment or even the thing I recalled, it was that the live wire goes from a +ive source to a -ive source, attracting and then repelling electrons, but it does not really matter, because all these electrons want to do is get to ground the source & sink of all charge. This source & sink of all charge is more commonly known as the neutral wire.
It was a big day, last night I found a Youtube vid on how to make quizes in google docs ... I have no sound hardware on the machine at home at the minute and so saved it until later when I was in school. So at lunch In S8 I watched the vid .... no sound on it either .... and by period 8 had a skeleton 'quiz' online....
Hope it is as good tomorrow
