Idea Open Day Ideas

I saw this practicalphysics.org/physicists-play.html whilst looking for something else.
The pdf on the "experiments for a special day" has lots of ideas that could be added to your repertoire -or give a break from the same old stuff. Physics tends to lack suitable demos, so this all helps,Although on the IOP website, how appropriate they are may be open to questioning..

Technicians: providing solutions and more.

My favourite experiment is there - Conduction of Glass - though I have a slight extension to it. Haven't done it since the Head of Physics, despite my best efforts, tried to electrocute himself with it (it was actually very unlikely but I made my point and scared him significantly!) CLEAPSS has a SRA that makes it completely boring. Similarly they (read: the person asked to write the SRA) "can't see the educational value in electrocuting a gherkin" ... actually, nor can I but, apparently, it stinks terribly when it lights up like a flickering fluorescent tube ...

Educational value is more than just number crunching and remembering facts. (even that is all they are rated on at the end of the two/three years)

Chemistry has bang, fizz, flash, booms.
There is little educational value in them as well, you can easily tell the kids what whould be happening and even give them a video.

But there is nothing like a link WOW and I dindn't actually believe that would happen, to get them chatting.

I agree - which is why I still have a risk assessment for my version of the conducting glass demonstration.
However in the glowing gherkin experiment the poor vegetable, as well as being pickled, is shorted across the mains with exposed probes and the whole assembly is generally hazardous! :-) If there's no real merit to it, why take the risk?
