I also feel for the parents of the "naughty" children.
I would be devastated like they are, that my child would do that.

Hi All

Did anyone attend? How was it?

There isn't much quiet here working in the holidays......I bring in my CDs (and attempt a sing-along) and I put on the lab TV (to catch up on Oprah-ha ha). It sure can be peaceful though. I started back in 05 when there was "work choices" and talk of teachers having to work through the hol...

I will have two weeks mostly teacher free and definitely pupil free ......HT comes in to check where I am up to on the list of jobs.

Only six months til holidays but who's counting

Enjoy your break

Hi All Went well this morning and one more class this afternoon. Plenty of newspaper on benches and dedicated food equipment. Teacher had choice of cups, plates or bags (lucky I had stocked up). Used cups as the cell wall. The children were that excited! Those students who followed instructions abou...

Hi All

Does anyone have a recipe for making cells with jelly and lollies please?
I have to prepare for pracs tomorrow. I'm not sure on lolly types or quantities of jelly. I remember something like jaffa for nucleus and nerds floating about.

Any help appreciated

We use more of a demineralised water. The uniy we use is a cylindrical unit about about 350mm high and base about 170mm diameter. A hose is connected from the unit to a tap. Water passes through a cartridge (similar to water filter and you have next best to distilled water. We have had no problems f...

I have to ask the teacher to turn their classroom gas on so I can use my gas taps too.

We use saturated potassium nitrate at times. No problems so far. Crystals grow in plastic petri dishes.

flour in a coffee can

Thanks everyone.
I had made the 4M for seniors only and teacher wasn't impressed. He doesn't like the dilute solutions, prefers 2M or 4M to hasten the reactions. Uses stronger HCl with Magnesium or Zinc (mainly for pop test).

Hi All
CSIS has for Hydrochloric acid:

>4M <10M suitable 11-12

>0.2M <4M suitable 7-12

My question is ""What do you class 4M as being suitable for?"

Hi All We are getting back into dissections here. My butcher told me he is expecting eyes, livers and plucks etc in the next week or so and he will give me a ring when they come in. I know to freeze eyes in dilute salt solution. Had no problems with frozen kidneys. Are there any tips for freezing th...

Try your local chemist. Not sure of price. You mix it with warm water for a mouth wash.

Hi I am in Nowra and received quotes toward the end of last year for servicing of all our microscopes. Issco had a minimum of 15 microscopes and were substantially dearer than EduSupplies Pty Ltd. We used EduSupplies Pty Ltd @ $35 per microscope. They also called in at another local school after us....

I have had a look at the workshops for Lab Assistants. Can't see school approving attendance for partial days of workshops. It is a shame too that workshops I would like to attend are on at the same time. St Mary's is my preferred option as two full days relate to Lab Technicians.

Hi again
Serrata sell it 5mm #1102050 $18.45
6mm #1102051 7mm#1102052 $18.45 all per kg (approx) in 1.5m lengths

Science Supply Australia (in Vic) also sell it but in 700mm lengths

Rita

Hi
I am in the same boat....so to speak.
I rang Haines last week and they no longer supply it. The glass was wrapped in bubble wrap and in tubes but usually arrived broken thus making it not worth keeping in stock.

In my past life I worked at the local paper mill and we made this paper. My job was to make the diazo solutions to coat the paper for the print testing. It was quite messy and trichloroethane was the solvent for cleaning. Those were the days....... In recent times I was asked for paper "that fa...
