Australia's Science Forum

I have some barley grains that I keep in a glass jar. That works well.

We've had a few sawn off chairs here too.
My response when I first saw this: who thinks of these things?
Really????????????

Hi Judy.
Search iron thiocyanate in the search box above and you'll see previous discussions on this.

I'm pretty sure ours turns on automatically early in the morning - maybe 5.00ish and runs all day until maybe 5.00ish in the afternoon.
It broke down once and the fumes were ok but I wondered why I could no longer hear it running. Reported it and it was quickly repaired.

We are a very small school so these things are a lot simpler here. Our Food Tech teachers meet with the FT assistant once a week and they work out what each prac lesson will be doing and what will be needed. It doesn't take long because there is only one combined 9/10 class, one Year 7 class, 2 Year...

This is what we use very successfully.

I have recently been given a credit card to use for my purchases. I buy for Science and for the library, as I divide my time between the two.
Makes life so much simpler. We have not had petty cash for years and will not be refunded if we spend our own money.

I have been sticking with Riskassess lately. It is so much simpler and CSIS is so out of date it's crazy!!

Sean is very happy with Riskassess.
To be honest though he probably has no idea about chemical labeling and codes etc.
He lets me run my own race with that.
He travels in the Physics world rather than Chemistry.

My HT loves it and I'm pretty happy with it too.
Especially the labels.
I had the same moment of confusion when the extra box appeared....................

I have printed off a couple of SDSs for our FT assistant. I can't remember what for - most likely laundry products like bleach or some such. You've just reminded me about them - they're probably out of date now. I'd better check.

Nothing here.
We used to be treated like royalty for a few days and end with a big morning tea with us as guests of honour, but under new management: nothing.

Short of using the microwave, perhaps heating in a water bath?

I couldn't manage without my cranky old microwave

Yes this is what I usually do.

If in doubt, make your own calculations using the molecular weight of the chemical.
I have to rush off to a meeting now but I'm sure someone else can explain. Once you do this, you'll wonder why you ever had to look it up!

I work in a government school in NSW and I am an Admin Officer. I work in the library, office and Science because we are a very small school and we have to be flexible. I feel that Science is my home, though.

I have had all sorts of issues with MTA. Not buying from them again!!
Just yesterday I received an order from them from September last year, which I actually cancelled in November, so wasn't expecting to receive it ever.

I've had so much trouble getting things paid for properly and dealing with the discounts offered by Bill and then not followed through on the invoices, also large orders come in in dribs and drabs, so I have to do multiple confirmations for each order. I can only throw my hands in the air and not or...

Your local Rotary Club may collect to send overseas, or know of a charity that does.

Still nothing......................
