That had crossed my mind as well, but just can't find anything to confirm it!

I did a quick search and couldn't find anything... are there any conferences coming up this year other than conasta (which I can't get to )?

Does anyone know what v.s. means on the prepared slides? I can work out/look up most of the others but this one I am stumped on. Specifically looking at a lung tissue sample, but I know I've seen it on other slides as well. Google hasn't helped!

I'd be interested, too. How long do they last on glass? How easy is it to remove? I agree - students would be less likely to write on desks etc with them. We actually used to use them on the BA board and tally tags (to keep track of where everyone is on the fire ground etc) when I was a fire fighte...

OK perhaps I should have googled first! They are the same as a chinagraph pencil. I've just never seen coloured ones before! Anyway, I'm still interested in learning if anyone uses them at school

Has anyone ever heard of these? https://www.chemtalk.com.au/viewtopic.php?f=26&t=451/product/42055/grease-pencil-for-glass-writing/ If the link doesn't work, go to Wiltronics and look up grease pencil. They are obviously more expensive than permanent markers, but possibly less risky for being st...

Thanks! That's what I suspected, but couldn't find anything for any type of litmus just to be sure. It's such a crazy messed up system...

Does anyone have an sds for litmus paper?

I was here for the start of it (2011 - I'm RosalieM on page 1) but not the 2015/2016 discussion. I've printed out the document linked from November 2015 which looks kind of official and put it with the rocks to deal with later!

Thanks I have emailed both places. I'll see if one gets back to me next week and then try making phone calls...

I decided to set mine after all. I came in this morning to two pracs, both ordered and done this morning before I arrived. They knew I was going to be late today and got their own stuff out, but still...

What ended up happening with these rock sample kits? I have no idea how old ours are. I am currently sorting and relocating them (and by "I", I mean mostly the teacher who has a background in geology!) so it's a good time to make sure we don't have things we shouldn't...

Has anyone on here ever bought real copper ore? Not looking for the "home made" stuff we use in science. The Ancient History teacher has asked me about it! I said I'd see if I can find out where/how to get some. I haven't ever needed to purchase rocks/geology stuff so don't even know where...

I've only just found on Riskassess there is a Warning on short-notice bookings / Cut-off time if you go into the tools section. I don't know if I'm game to set ours most give me 2 days notice but HT believes 11pm friday is fine for 9.10 Monday :cheesy: :cheesy: :cheesy: Would love to know if anyone...

Supercheap Auto also have trundle wheels with counters up to 999.9m for $34.99

Sarah B, I find that there are really busy weeks when the prep room ends up looking like a cyclone hit and then there are quiet weeks when I can catch up and put things away. The teachers should be doing the risk assessments themselves and you should only be doing the risk assessment for the work yo...

Can anyone help me and give mean idea how to dispose copper nitrate?
Thank

How much do you have? Is it solid or in solution? Usually it is kept for chemical waste collection.

Hi Just wondering who to use in the Newcastle area for servicing microscopes? Just wondering if you found someone? Also, does anyone know if there's a course I can do to refresh my microscope cleaning skills? I did a session back when the St Mary's conferences were a thing.... then was out of scien...

Jumping in on an old thread here... Just wondering who still prints out the RAs if you use RiskAssess? Also, a thought on NSW DoE not needing to do RAs because of the CSIS, how many teachers actually reference the CSIS when ordering their pracs? Do they check each time that the chemical hasn't been ...

Are you able to take a photo of them for him? or one of the teachers? The only potential "problem" I can think of would be if condensation formed inside it might go a little weird... are there other plates in the incubator? Can you just turn it down to whatever the lowest setting is or wil...
