Re: Lighting Bunsens

Re: egg drop
Morning Rosalie,
We give students 6 A4 sheets of paper (great for used paper) and 1 metre of masking tape. Teacher drops egg standing on a ladder (from approx. 2.5 metres high). Always interesting to see how students think!

Re: BYO lab coats?
Hi Rosalie, We use aprons for junior classes (vinyl type) that are hung on hooks in the labs. We provide lab coats for seniors that they care for during their time of senior science and at the end of Yr12 they wash them and return to us for the next lot coming through. I wipe down the junior aprons ...

Re: Banning certain plastics in schools
OMG! Can they challenge us with more things? I have carefully hoarded these things too.
I have read somewhere that balloons are being considered for banning. Alternative - sheep stomach?

Next week we are going into Oreo Moon Phases... I ask you, do we really need to supply so many Oreo biscuits that we buy the su...

Re: Potassium Permanganate Disposal

This morning I tried putting some in a small beaker of potassium permanganate waste and it went clear. Are there any chemists out there who could te...

Morning, I usually have purchased my chemicals through Westlab but now the new system of not being able to view chemicals and prices unless I am a registered credit account is a pain in the neck.

Re: RiskAssess chemical codes
Morning everyone, I have been reading with interest about the conflict between CSIS and RiskAssess. I am of the opinion (not knowing what date CSIS was produced) that Philip Crisp makes his bread and butter from RiskAssess and can't afford to be wrong. Having been one of the people who originally cr...
