Re: Bones
This is seriously one of the best threads ever!!! I have lots of bones. But no human remains. I did have an appendix and a cartilage at one point, long since disposed of. I did collect skulls after a bush fire to go with my existing animal ones. We have porpoise bones and rabbit, from a kit all Vic ...

Re: Extracting oils
Depends on your garden. You could bury it a bit. I chuck mine in our crappy area around gum trees, not in Summer though.

Re: Making sterile agar plates
I use a bit of boiling water to help dissolve the nutrient agar, add distilled water, put it into conical flasks, cotton wool plug, autoclave, (I use a pressure cooker), this kills everything. You do not have to sterilise anything. I use unopened bag of petri dishes. I wash the bench surfaces in a d...

Re: Welcome 2025
Welcome back everyone. I had a quiet one, animals and gardening duties. Baby chicks aplenty, vege patch and orchards looking better and alpacas shorn. I am taking time to have adventures on the days I don't work, while there are no crowds. Beach break booked. I have lots of new teachers and feel exh...

Re: Maggot activity study for the forensics class
I will use your pics. Many years ago I had a teacher set this up in the fume hood with left over heart dissections. She didn't tell me and back then the fumehood was at the back of a classroom. When she remembered it was abuzz. I bailed. Teacher had to do the clean. I have never done it since.

organic solvents
organic solvents would include alcohols, esters, ethers, ethyl acetate, ethanol, acetone, benzene, and ketones. A work colleague's husband recently had a lung transplant due to lung disease caused from exposure to "organic solvents". Last year I had an unexpected lung cancer diagnosis and ...

Re: phosphoric acid and methyl violet
To get the NO2 I use a quick fit set up and put the tubing up through a beehive in a trough of water, I have the test tubes ready and wear full PPE and do it in the fume hood. Sometimes I used a gas jar and for another prac, gas syringes.

Are multimeters any good as a substitute? They are so cheap. I have older meters and dread getting them out for junior classes.

Re: Identifying rock samples
We just did a geology PD with our lab tech group in Gippsland, I will see if I can find the links we were given. It was from james.driscoll@monash.edu James was great and there are ID pages and lesson plans he was happy to send us.

Re: phosphoric acid and methyl violet
There is 2 more parts to this prac. per student: 5 x 10-4M Fe(SCN)2+ solutions. and 2 x stoppered test tubes containing an NO2/N2O4 mixture. It's in my old Heinemann Chemistry TWO teachers resource book. We aren't running yr 12 chem atm so I don't have the current prac book. I remember it worked wel...

Re: Hydrogen peroxide
I don't store 3 or 6% for long in dropping bottles anymore as the rubber teats blow up, but never burst. I decant the solutions into a screw top bottles and have never had a problem. Never huge amounts as I am a small school. The 35% is always stable and stored in 5.1. If anything it may become less...

Re: Distillation flasks
Years ago I got new components made up from Haines, the size available was not compatible with all my existing quick fit. Mine are 24/29. Haines were very helpful. Expensive though. I have never had the need for 1000ml flasks but have had some donated from a research facility.

Re: Radioactive sources -safe disposal
The Cs-137 generator is actually really handy, I'd be surprised if you couldn't find another school in Tas to take it off your hands. It's a fast, simple, safe and clean way to show radiation decay in the classroom. I'd take it from you but we already have 2. I would ask your science teachers to co...
