Thank you for the booklet, it is GREAT!

PS Big thank you to DEBBIE!!!!!!!!!!

Hi Merilyn,
If it's not too much trouble may I have a copy of your booklet too? I have decided our open day ideas are old and jaded... we need a change!

Good morning, I have Risk Assess and Chemical Label Maker. Chem label has more detail but is good when you want to make your own label - but RA the preferred label maker for me. I would suggest go with RA as Philip Crisp has been involved in Chem Safety for many years and has researched what is lega...

When it comes to flame tests for juniors, I soak paddle pop sticks in saturated solutions of barium, copper, potassium, strontium and sodium chlorides. I find this is less mess. Works well for open days too.

Vacuum packing them then freezing seems to work well....

We have those and so far (touch wood) no complaints.

Why is it that the powers-that-be feel that chemicals stop fuming for certain periods of the day?

It is refreshing to hear common sense Linotas but, we of the bottom rung order need to be wary. Superbug, I am with your thoughts of the RiskAssess labels and have mixed feelings about it all. Firstly, the print size can only be so small (it is 8 the minimal requirement?) and secondly, I have seen s...

We use Vernier too. Only problems so far is operator error.

Scientrific representative is happy to come and teach use of or demo product.

Don't know if it's interesting but we use Heinemann's....

We use LDPE disposable aprons. They come in 100/box $12. Quite frankly I got tired of washing aprons that had been used (put on) and not dirty, but who could tell because they were old and stained anyway....

Hope the packaging is the edible kind! You can use it for starch solutions!

This is the experiment we do - hope this helps.....

My local Woolies always say that if I like I can buy aspro in several transactions in the one visit. They are happy to do it this way because of course they know I buy them for science. Maybe your Woolies will do this for you?

Have you tried sticking a fine piece of wire up the end?

Oh Smiley!!!
How I've missed your humour!!!!!

Morning all, Under the heading "chemistry" in this thread, I have posted what we use for sulfate content in lawn fertilizer prac we use. It uses barium sulfate and an agar congealant to get results. We find it easier and more reliable to get good results in preference to trying to filter t...

Hi all,
I hope the prac works well for those who try it. Glenpaul, I think the pdf is till available on this page for you to download. Let me know if there are any problems.

Here goes, sorry about the writing on the pages....
