Hi all One of our students would like to do his IP on something relating to the bushfires. eg: models of houses on the ground or on stilts; built from different products. It's great he would like to do something relevant but does anyone have any idea how this could be done in a safe controlled manne...

Re: Chemical waste bottles

I was planning on having waste bottles for organics; inorganics (cobalt,copper, strontium); lead; nickel; chromium; zinc; silver. The 2.5L Hdpe bottles chemicals come in are stable so I would not be too concerned about them tipping over if they can be used for waste storage, and if I can source them...

Re: Chemical waste bottles

Hi all Having just done my first ever chemical waste pick-up in the 15 years I have been here, I am now trying to be more conscientious with chemical disposal. I am following the advice on Science Assist. Does the wastes need to be stored in glass bottles or can some be in plastic? Where have you so...

We have already done many of the typical open day ideas. I was hoping to get some different ideas specific to this years science week theme of sustainable oceans.

science week 2020

I know it is a long way off but my HoD has asked me to start thinking of ideas for science week so he can apply for a grant. This year it is on
‘Deep Blue: innovations for the future of our oceans’
Any ideas for lunch time activities and experiments for primary kids?

Re: Egg Incubator

That sounds horrific. Good on you for not having anything to do with it. I suspect that without your help, it will be too much effort for the teachers - they won't want to do all the prep and cleanup!

Re: Magnets

Good to get this info. The last lot of bar magnets I bought are absolutely hopeless so I have been reluctant to purchase more.

sealed radioactive source

Hi all

Do you have an SDS for your sealed radioactive sources or do you just use RA's? I have a very out-of-date SDS but can't find a recent one.

Re: LPG limits

My understanding is we have to do a stocktake and have a record of all hazardous chemicals, easily available incase of fire, but as long as we are below the stated thresholds, we do not have to apply to Safework for a licence. Although it is my least favourite job because it takes so long but no one...

Re: LPG limits

As expected we are nowhere near the limits of what we can store onsite without having to notify Safework. However, it is great to have this confirmed in writing. See attached the limits for NSW - other states may differ.

Re: Antibacterial hand sanitiser

Every year I have "discussions" with the Junior School teachers about ethanol based hand sanitiser. I tell them it is ok for under Yr 7's to use it as long as it is stored out of reach and monitored by the teacher. They insist that being on the teacher's desk is sufficient monitoring. I passed it on...

Antibacterial hand sanitiser

Our preschool has recently purchased some new hand "sanitiser" as they are not allowed to have the ethanol based sanitiser. After looking at the website for Siqura I felt a little suspicious of their claims. "Unlike traditional alcohol based hand sanitisers that only provide short term protection, t...
