Wow! Hopefully that will solve issues of consistency and access to labels for molarity of solutions that so hard to find in Chemwatch!!

Just wondering what sort of gloves everybody uses for handling chemicals and then general washing up etc?

I just find the volumes at times are ridiculous. And there are other pracs that can demonstrate the same things without creating a mess.
Does anyone else have thermometers that measure up to 200deg? All ours are 100 or 110. Though we do have old mercury thermometers.

I find a lot of the pracs in the national curriculum text books impractical. Stage 4 chemical reactions honeycomb type prac needing thermometers measuring up to 154 deg ( because we all have sugar thermometers for toffee) and 110g sugar per group.

Try Redbank Instruments at Picton. You can google them for contact Details.
Also Bob's Instrument Service. Bob Death 0416 721 011 He is at Bangalee. He dropped in a brochure. I didn't meet him but he may be worth a try.

The chem teacher ended up warming up the beaker and then adding hot water to the top of the sugar in the beaker. The reaction was almost instant!

I ended up doing 70g sugar and 70ml of sulphuric acid. I gave it a stir and it went black and I thought it wasn't going to work again. So I went in search of different sugar and when I came back it had worked.

Interesting. Ours is very old too. I haven't bought any in the 10 years I have been here. Of course I need it today! Anyway I have done it again with proportions I found on line and it worked!

We have had a disaster this morning. Having used buckets of sugar and tons of sulphuric acid we now have dozens of beakers contaminated and not one of them worked. (I am exaggerating) However we haven't been able to get this to work. We have wet the sugar used the proportions suggested in CSIS every...

Hi Rita,
I think it goes without saying that if you are ever in need of guidance, advice or even just to blow off steam you have a ready made brains trust in this site to help you whenever you ask!
Great bunch with a huge depth of knowledge and experience!

Hi Narelle, I still haven't received any information for the conference. Are you able to email me a flyer? My email is mueller@oxley.nsw.edu.au

Hi Rita, Welcome to the mad mad world of School lab assistant. I have never heard of this data logger. We use LabQuest. Very easy to use very user friendly. Expensive though at around $560 a pop plus probes! So yes a huge investment for any school and well worth the research in getting the one that ...

Me too!

Because stupid people do stupid things and apparently need to be protected from their own stupidity. Natural selection be damned!

Can't find it. If you are interested PM me with your fax number and I will fax it to you unless someone else can find it. It was from 2008.

You could do the borax crystal prac with the pipe cleaners shaped like Christmas trees or stars? I will find the post.

Hear Hear!!

You sure it was the phenolphthalein and not operator error. Maybe they added acid to acid.

I self checked out last time I bought 6 packs of alka seltzer. It did set of an alert but I knew the girl who came to assist and she let me go!!

You could try Redbank Instruments. Google them. Not sure how far they will travel though!
