And you can also buy slime made from sodium tetraborate from retail stores.

Until something goes wrong!

Last year we had a minor incident with vinegar getting in a students eye. I had to produce the signed riskassessment.

Thanks. I was looking to replace my current ones that can't go in a dishwasher (other than that nothing wrong with them and will be keeping them for other uses) and didn't want to get them and be no better off.

We had those Grey shallow trays at old school to Rosalie . Apparently they were Photographic development trays . I couldn't find the original ones for Love nor Money but I did find some Newer ones .They all had a small pourer on one corner . I thought they looked strange but the Bio teacher said it...

Here is a presentation from the 2020 TALM Conference about radioactive sources and disposal in Tasmania. Might be helpful to you.

To stop matches going down drain and many other things. Get a sink drain strainer thing for Bunnings and just a couple of drops of hot glue to hold it in place. Exactly what I did to every sink in Science. The GA and I got sick of fishing pens, pencils and other stuff out of them This makes me fell...

Phenolphthalein seems to be the standard when titrating. It is worth noting though taht the colour change isn't at neutral either with phenolphthalein.

AS you can buy Biuret Reagent from science suppliers, I'm sure it is perfectly fine to send to the classroom mixed together.

I've attached what we do. It is a bit more intensive than the zip lock bag method, but it eliminates the use of bags which is good for the environment.

Thank you for the replies. I have passed the info on.

I have been asked to post this on here by another school. The following is the procedure that was put on Riskassess by the teacher requesting the prac. It is to be a teacher demo. 1. Add a third to half of a teaspoon of solid CuCl2 to a medium beaker (250 mL). 2. Add approximately 5 mL of ethanol an...

Southern Biological sell them (they have them named as autoclaves).

Also from Science Assist, Laboratory pressure cookers must contain a pressure gauge, a control and pressure relief valve and be able to reach a pressure of 15psi (103kPa) and a temperature of 121°C. These sterilisers can be purchased from biological suppliers however costs vary and schools need to s...

Taken from Science Assist, Microwave ovens Microwave ovens are not a suitable alternative to an autoclave or laboratory pressure cooker as they do not provide moist heat in the form of steam under pressure and therefore, will not sterilise. Microwaves penetrate unevenly and there can be ‘hot spots’ ...

Science Supply Australia and Omega Scientific both sell film canisters as well. A bit more expensive, but might work out for you.

I just set mine for 1 day notice, to see how it goes. I haven't told anyone about it

As for teachers checking CSIS - it seems rough that Labbie says the labbie was responsible for checking this. You would think that checking the rating on the chemical would be part of the teacher's risk assessment?? I totally agree Merilyn. The teachers are the ones in charge of the class doing the...

When you check their website it says;
"Do not send in medical waste, this includes material contaminated with blood or bodily fluids. Other types of protective gear like hair nets, ear plugs, and lab coats or garments are not accepted in this box."

Dynamic Science sells rocket kits.
