Re: Rehabilitating Plasticine?
There is a difference between playdough and plasticine (says the mohter of 3 under 8 lol). Playdoug you can just add a small amout of warm water, pop a lid on a container and check it every day or so. Plasticine aka modeling clay I have no idea. However, it doesnt get as dry as playdough as I suspec...

Re: Xylem & phloem?
I have never done that prac (am newish to labbie land) but my thoughts would be you are not cutting the section thin enough? How are you cutting the cross section? do you have a hand microtome?

If you have a good look around there is heaps of info. Although the "summary" book to the official GHS document is 90-odd pages long

Re: Chemffx Labels
Fibreweb, do you have an example? The classification and DG codes are different under the GHS, so the pictograms will change. There was a link on here somewhere to some info on the GHS which, with a little bit of searching, I found the new classification and pictograms (whcih you can actually print ...

Re: Where do you got your information from??
Although not in NSW, I get a lot of stuff from the OH&S supervisers at my schools. One is far better then the other for getting info to me. Under the new GHS, the Principal is the (and I cannot remember the actually wording) the head honcho when it comes to OH&S responsibility. So if he/she ...

Re: Chemffx Labels
Why the rush? We do not have to be GHS compliant by the 1st of Jan. I am updating my labels as I need to print new ones.

Re: Chemffx Labels
Do you use PC's or Mac's? Chemwatch was not set up for the Mac OS so it has some problems. Most of the problems I have found has been with formatting. I havent had a problem with the Windows.

Re: Flame test kits
Probably wont work for a prace exam but we sit up a different station for each chemical so there is no way they can be contaminated.

Re: Fixed Resistors.
I really have no idea, but a resistor + liquid seems a recipe for disaster for this non physics person.

Wow, I've been a OH&S auditor in a previous life and there is no way that should pass a safety audit.RosalieM wrote: but either way, something went wrong in someone's thought process somewhere!! But they pass inspection every time so I guess that's good enough for 'whoever'!

Re: Glass Making
Wouldn't glass making require extreme temperatures and/or pressure? I wouldn't think it appropriate for a school prac.

Ian I've tried that, obviously I'm not as dextrous as you as I get water everywhere and nearly drop the bucket on my head!! The maintenance guys think they can whip me one up, so all good.

Safety Shower testing
Do you test your safety showers as per the standard?
If so, do you use a safety shower sock?
They seem quite expensive and I am going to see if our maintenance guys can make something up but just wanted to see what others do.

Thanks Smiley. I might suggest it to our new (read first year out, first job) physics teacher for next year. Sounds like fun.
