Re: Jacaranda Science texts
Dear labgirl,
I was just looking over some resources we have finished with.
There are some (3 and counting) copies of Jacaranda Core Science 3 but their ISBN is 0-7016-3388-3. Can you use them??

Radioactive source storage
Hi All, does anyone know if there is a safe storage box for radioactive sources out there yet?? We have always used a petty cash tin lined with lead, however upon testing the box with a geiger counter, there is not much change in the reading from the unprotected sources. Surely we deserve a proper, ...

Also bringing to mind that as a subscriber, the Chemwatch Bulletins contain refreshed information that apply to technicians in schools as well as the...

Re: Paper towel dispensers
Hi, I was just scrolling around and came to your post. When we designed our new building 5 years ago, the school outfitted our 6 labs, 3 prep rooms and staffroom with paper towel dispensers. The labs have the Tork continuous paper towelling and the prep rooms have the interleaved ones. Our prac requ...

To lock or not to lock?
Hi All, we have our main prep room off a corridoor which has no student access. All our chemicals are stored at the far end of this preproom in their own rooms and out of sight. Yet the school inspectors inspecting us for our re-accreditation want all chemicals under lock and key even when we are ne...

Re: Fe(SCN) waste
Hi Jenny, when we have aqueous solutions of chemicals that can go to landfill, we allow them to evaporate somewhere safely (can take up to a year), then dispose of the dry waste to landfill. Waste disposal companies charge by the quantity as well as the type of chemical (ie those that can't go to la...

We put only 8-10 matches in each box also. It's funny how they are careful with them when they can see there is a limited supply. We even get some matches back. :D Now.......how to keep the spent matches out of the sink and lab kits...... We have galvanised sand buckets in each lab but they are not ...

Hi, we have been down this path many times. There are flints and flames to light bunsens with, even ones made by the Redhead matchbox people. Always, always the kids keep them in the flames until they melt or are destroyed, they are not cheap and to get one for each lab group has not worked. We alwa...
