Hello
Can you all tell me what text(s) you use for the Australian National Curriculum?
We are only starting next year and wonder what text you all think is a good text.
Also, do you have actual texts for the student, or e-books?
Thanks

Is there anyone out there from SA schools using RiskAssess? Can you let me know what you think of it?

Re: How to make nutrient agar
Doing a google search for alternatives to peptone, I found a biology-specific forum site (almost identical to this one) which seems to be international.

Re: Only in the Top half of Australia!
I remember the one in the Mulgrave road drain. I was working in the Federation / Muir Street area at the time. I miss Cairns...I was only there 6 years but I still felt more at home there than anywhere, but my wife hates humidity so here we stay. Having said that, she's from Canada and I'm trying to...

Re: Need help
I think you are confusing HCl with conc H2SO4, which is normally about 98%.RosalieM wrote:Conc HCL is usually (I think!) 94-98%
HCl is actually a gas, so 94-98% would still be a "moist" gas! The conc HCl I get is 32%

Re: Non slip mat for eye wash stations
Our's have a drain in the floor near the shower. Not surprisingly though, whomever designed/installed the flooring/plumbing didn't put the drain at a low point in the floor, so any water actually flows away from the drain. At one location, water drains to the right an directly under the chemical bun...

I'd recommend that he wash his own whiteboard erasers. Teachers here know that I am not going to waste time doing things like that for them.

Re: Conc Sulphuric Acid
The acid is still fine. The colour of conc Sulphuric ranges from colorless to dark brown depending on the level of contaminants, but will still work ok for ester production and most school purposes.

Re: Ammonium nitrate
Most nitrates are endothermic with respect to solubility. Other options are citric acid (just use the cheap stuff you get for baking from the supermarket) or sodium thiosulphate.
A really good demo is ammonium thiocyanate in water - check out video demos on youtube.

Ours get checked as part of the Site Maintenance Schedule and the cost doesn't come out of my budget so I don't really care how often they do it

I suspect the initial conc of Ammonia in Cloudy ammonia may well be below 2M in the first place.....

Re: Ammonia
I believe cloudy ammonia may have a small quantity of soap added to it. I personally wouldn't use it for lab solutions.
Also, I'm not sure of what is printed on your bottle with regard to concentration, but you'd obviously need to what you were starting with to be able to produce a 2M solution.

gave up on ammeters and just use multimeters - it's easier to replace fuse
