Re: Yabbies
Yabbies are mostly vegetarian. I feed mine yabbie food, cooked beans, cooked peas, and other cooked vegetables - pumpkin, carrot, broccoli - but remove anything not eaten after 5 minutes. I also give a worm or piece of fine chicken slice once a week. They love to hide so have something they can shel...

Re: GHS on Mini SDS
I put the mini for each chemical in with the experiment and they are used by the students to read the safety information on the chemicals they are using.

Re: Chemical disposal
I use sodium carbonate, stand to precipitate, then decant the solution and wrap the solid and bin it.

Re: Practical record keeping
I was told during my chemistry TAFE course that the minimum legal requirement was to keep a diary with the experiments ordered. I buy a diary with Science funds each year and I write the teacher's name, the class and the equipment and chemicals, etc that have been ordered on the date it is being con...

Re: Multimeters
We use digital multimeters all the time. When the ammeter is not working it's usually because the fuse inside has blown. Just replace the fuse and all is OK again. I get a lot of use out of the batteries - only had to change them once in 5 years.

Re: Year 8 chemical changes
Mixing methylated spirits with water, soaking a handkerchief or cloth and then setting it alight. They are always amazed that the cloth doesn't burn.

Our local fire brigade receive a copy of our chemical register and a map of the school with the stores marked so they know where the chemicals are stored and what is stored there.

Re: beam balances.
Ours are used every year for year 7 - Working as a Scientist and then they are used periodically throughout the year. We also use them for the year 9 practical assessment weighing tasks and have a digital balance at another station as well.

Re: Biuret Solution
In the CSIS appendix B Biuret solution is orange dot - years 11-12. Toxic if ingested. Corrosive due to the presence of the sodium hydroxide (6M); avoid skin contact.
For junior school we use 0.1M copper sulfate and 1M sodium hydroxide - green dot.

Re: Glassware in labs?
I was just listening to Alan Smith on the DEC Webinar about the new CSIS package. He stated 'If you don't have perspex glassware to replace soda glass you are running a risk'
Does anyone have perspex test tubes that they use consistently?

Re: Bromine water
Hi Labbie
Appendix B has bromine as a teacher only chemical and instructions on opening an ampoule (cool first). I still have 2 ampoules left and intended on using them up. Where does it say we are not allowed to have them any more?

Re: Is borax really a teacher only chemical?
I contacted Phillip Crisp about lead nitrate. RiskAssess has it as teacher use only for 0.1M. CSIS has it as years 7-12. He replied that CSIS is 17 years old and now out of date and RiskAssess is current knowledge. We still use RiskAssess to do our experiments but when something is different - like ...

Re: risk assess tips or tricks
I don't make changes to the teacher's risk assessment but if they have left off items - particularly minor equipment - then I add it using 'add review notes' so the next time someone wants to use the RA they can add these things in the right place.
