I hadn't thought about the glass not being able to be recycled.
I won't feel so guilty now when I put it in the skip bin.

Hi guys,
I hate to be a spoil sport but we were told the money for new labs. doesn't include prep room upgrades.
If your prep room is dangerous though I would be letting the OH&S committee know before there is a serious accident.
Good luck.
Helen

Thanks for that info. everyone. We have special bins for broken glass but the teachers get the kids to sweep up the glass which is how the accident happened. As we have labs in 3 different areas I can't be there to pick up the pieces in all areas so will have to suggest the teachers do the clean up ...

Hi everyone, Just wondering how every one deals with the glassware that gets broken in the labs. Do you have broken glass bins in each lab? Do the students clean up the broken glass or is this the responsibility of the teacher? We had a girl cut herself putting some glass in the broken glass bin so ...

What a classic!
Here the main concern seems to be that every one has their top button done up. Doesn't matter what you are doing as long as that top button is secure.

I agree try stronger acid.
We use 2M very sucessfully here.

Good idea Richard,
There are a few girls here who would be very upset if their hair was messed up a bit. What would the boys at the station think?
I did find an old cane in the store room so haven't completely discounted the idea of a thrashing.

Hi everyone, Our school is having their 50th anniversary and we are putting on a science show for open day. We are already doing a few fun chemistry things but does anyone have any ideas of anything we could do to recreate an old fashioned science lesson. it would have to be legal to do it now. ( Ou...

Hi Rosalie, I just checked my recipes. Litmus says boil 10gms in 500mls distilled water. Stand until powder settles and filter. I guess this is similiar to yours. My Bromothymol blue recipe says only 0.1g in a litre of distilled water. If green add .4% NaOH a drop at a time until it turns blue. Don'...

Hi Ellice and Karen,
I have faxed that off to both of you so hopefully you should get it soon.
Helen

Hi Lisa,
I have faxed that to you this morning. Let me know if you get it OK.
Helen

No worries Sue!
Glad I could help.
Helen

Hi Lindy,
I can send you a copy of the recipes we got at the conference at St Mary's. There is chocolate fossils and some lolly rocks. Not sure how expensive it would be.
Let me know your Fax and I will send it to you.
Helen

Thanks Lynda that is what we were doing so I will give that a go next time.
Helen

Hi Sue,
I have just checked this as our metals are stored with the NR chemicals too. According to the CSIS book zinc metal,lead and copper are all NR so can be stored in that section.
Hope that helps.
Helen

Hi everyone,
I think this came up once before but what are people using instead of ammonium nitrate for year11 chem. (we can no longer purchase this.)

Helen

Sorry Rosalie.
When I posted that message the web address for serrata was changed from the one I entered to chemtalks - don't know why!!! Maybe you can ring them.
Helen

Hi Rosalie,
Serrata has some in their general laboratory section of their catalogue. I don't know if they are the same as Haines.
Their phone number is 9651 3033 and they are in Galston.

Hey Guys, I spoke to the Q stores rep. and told them that the office max markers were useless and she said they had been getting a few complaints so she was going to look into it. We like the refillable ones from staedtler but Q stores hasn't got those any more. We did get some from Kookaburra so th...
