Sue, I make up the pH solutions and students add a fixed amount of buffer and H2O2 in each t/tubes, We did liver and potato cores and work well.
If you like I can give you recipe, very easy.

Yes, it is allowed for 11-12. Dont like using it, it is chlorinated hydrocarbon, possible carcinogen, and depleteds ozone layer.
Lada

I agree with Mardi,
kids come here from yr4, and it is the same. We have to make sure, that they dont overlap too much. I heard a dvd for yr5 today with fractional distillation!! All about long chain hydrocarbons etc. Really, what will they do in yr 10-12?
Lada

Yes, I too add my best wishes and hope you all are OK.
Lada

Thanks everyone,
just ordered the eyes and they were 40% cheaper than S.biological.
Lada

Thanks guys. I will check it out.
I have had delivery from S. Biological, no problem there, just would like something a little cheaper.
Lada

Can anybody let me know where you get your eyes from?
We are in Sydney, and used to get them from local butchers and pet foods but none of them can supply anymore.
Help!!
Lada

Thanks Superbug,
I used your suggestion and logged on OK.
Thanks, Lada

I have the same problem. We had been using chemgold and last term changed over to chemFFX and I had no problem using my old names, but this week cannot log on. Our school received email saying all schools have to change to chemFFX, but we had done that months ago. I have contacted AIS but had no ans...

Congrats Noona,
Bob and your mother in law are looking after little Violet.
Smiley, now now, I told you I DID NOT get sick, even self inflicted. Alcohol was too expensive to chuck it in the toilet.
Seriously, it was just perfect.
Are you back at work?

Well, just got back to work and the cruise was FANTASTIC. I did take tablets the first 2 days as the weather was a bit rough sailing out of Sydney, but did not get sick. Was well able to enjoy cocktails and all the unbelievable food.
We will do it again!!

I was trying very hard to talk teachers out of doing pracs today, but did not succeed. Only electricity and sound and light today.
But I have opened up booking folder for next term, and about 10 peacs written in already. Oh well, get on with cleaning today.
Have a great holiday ,everyone!!
Lada

Not sure if it is worth it, but you could dissolve it all in hot water boil it down and re-crystallize.
I have in past tapped the plastic container with hammer to loosen the chemical and then put between sheets of paper and roll it wirh glass bottle or again hammer.

Like Noona I stored mine in Hazchem store in plastic tub on the floor on its own

Thanks Julie and Annett, I have already bought Avomine on recommendation of a friend. It is a form of phenergan and I had a dry run last week, it should work well enough.
I am planning to have a ball...

Congrats, Noona.
My number 3 grandchild will arrive in Jan.
Second daughter for my son and Sassi!!!

We have booked a totally-not-like-me holiday. Going on PO cruise to Noumea, isle of pines and 2 more island.It is only for 9 days, as hubby and I are not sure, what to expect. We have always owned a sailing boat, so have done a lot of sailing on "inland waters". We have never gone past the...

And we have had an idiot boiling metho over bunsen. Spectacular ignition. The flame is reasonable cool and if you kill the gas at mains, the metho will burrn off pretty fast

Just thought of something. Last time we used very little metho, each student heated his own (about 10mL) and I boiled water in kettle, poured it into beaker, place small 50mL beaker with metho inside the larger and in no time at all it boiled. Since boiling point is about 78oC it will boil in boilin...

I have news for you!
I will catch fire even without boiling over.
The vapours are extremely flammable.
You will be safe with hot plate
