We have them set up in the display cabinet (all glass) similar to above with the teachers notes standing next to them, they are in the classroom so accessible for students and teachers. I do find them out during Yr 10 science. Make sure you glue the lids on..... and DONT use Super Glue it makes the...

Hi all, just thought thought I'd stick this on here https://elementsets.net/. they are so cool and free.

Yes we use these all the time and have a class set. We used then on a regular basis for CO2 gas and probably 4 times per year for dissolved. So we only purchased 5 sleeves for our sensors. They are so easy to use and have very good repeatable results. If you have the cash, a good investment. You run...

We use the mini SDS's out on the carts in the class, works well. Teachers are more inclined to pick up a mini SDS than the full one

Very specific.... can you use a different stain ?. New England BioLabs would be the people I would contact. https://www.neb.com/en-au They also offer small samples so you could try.

Only re-use once label has been removed

Excellent work, thanks for raising this. Just a good reminder to check everything . My biggest bill for waste was 2.5K one year and it was an epic clean out of old and nasty crap, 10 years of hoarding by previous staff ...... I think I'd die if I saw a 5K bill for a general clean out.

Congrats @MissKat

OMG !!

OMG !!!!! yes would never do a pop test with a gas syringe. Ours are used in the holders where they physically can't expel the plungers out all the way... for good reason as you've shown hey !!

Science supply sell them but awaiting stock. Could you borrow them from another school whilst waiting on ordering them ?

NSW, but we use it for handy stuff also in VIC

We do for some things but use Kitty litter instead...way cheaper

Yep, just the solutions and powders you buy... no diluted solutions. No glue sticks, spray and wipe ect.

I do however put the bulk chemicals the cleaners and canteen ladies have onsite as they nasty..

Southern Biological is a supplier for 3B.

One of our crazy old school chemistry teachers has a 1 M long piece of wood, has drilled little divots in it about 10cm apart. I fill each divot with a salt, we splash ethanol over the top carefully and light her up. Lovely in the dark all the coloured flames.

Our teachers do this demo. Is done in a fume hood and a lab tech is always on hand. We use smaller quantities though. I can't see an issue with it.

Same as above. I am not aware of any changes, ours come from Southern or from Monash Uni.

Do teachers have to do a RISK ASSESSMENT for all EXPERIMENTS ?
Thank you
Judy

yes, it is required of their role, for safety, to cover them and scheduling
