Re: Free elements sets for schools
Apologies is I sound slightly cranky, but after loading and labelling ca. 60K samples, and assembling 1600 sets across two rounds of sets (including the last bit I need to do over summer), most of it personally, it does start to annoy me when I have to wade through more than 1000 orders currently o...

Re: Free elements sets for schools
Thank you Stuart. They are really clever and already popular. I was on leave when they arrived. Haven't had much time to look at them and was certainly unaware of the website! So, thank you for the extra information.
Love your work

Re: Free elements sets for schools
Of course, I'm not sure how they glued the elements set!

Re: McCartney Bottles
Just a thought - is the top the same size as a dropper bottle? You can buy caps for the dropper bottles.

Re: Free elements sets for schools
I did have a thought afterwards. We put some mercury switches into these containers - tiny amount of mercury (so tiny, I couldn't really see the point). I decided to glue the lids shut and I had the casual use a really small dot of superglue to do so. That was twelve months ago and they are still fi...

Re: Free elements sets for schools
We have them set up in the display cabinet (all glass) similar to above with the teachers notes standing next to them, they are in the classroom so accessible for students and teachers. I do find them out during Yr 10 science. Make sure you glue the lids on..... and DONT use Super Glue it makes the...

Re: Free elements sets for schools
My coordinator got hold of these whilst I was on leave. Very neat.
Now trying to work out the best way to display/store them. Have you had any thoughts, Anna?

Re: microscopes
Seems that the repair people give Motics a good wrap. After lots of umming and ahhing, not being able to actually see one of these models, I have taken the leap and ordered some.
But thanks for the reinforcement of my decision!

Re: split pea DNA
I run with the idea that the senior students don't remember what they did in junior years. Once had a Bio class insist they had never used microscopes before! We just stick with strawberries. I buy frozen ones so they are on hand. We often do this prac out of strawberry season and the frozen ones ar...

microscopes
I'm looking to buy some new senior microscopes and have been quoted (among others) for Motic BA-80 microscopes. Just wondered if anyone had these and your thoughts. Also, as I'm in Tahmoor, is there anyone around Campbelltown or Southern Highlands that has these that I could have a look at? Apprecia...

Re: Safety data sheets
That's a good idea. Highlight the first aid and maybe the spill procedures. Invest in some Post-it Flags to indicate those pages. Good time to remind the teacher that they should be referring to the SDS when preparing their risk assessment for the prac, ie reading the SDS before they use the product...

Re: Safety data sheets
Mini SDS are not recognised by Safework as being a SDS, so they aren't much good on their own. You still need to have the correct SDS. Apart from a mini SDS not having all the required information, they are produced (by Chemwatch) a third party. The SDS must be provided by the manufacturer or suppli...

Re: Eyes for dissection
We've given up on brains, too (like a few people around here :cheesy: ). Last lots were in pieces, not whole. Teachers decided that the brain dissection is not worth the cost. However, things like hearts and eyes certainly have a lot of value especially for seniors. I've been on leave for five month...

Re: chemical register
Not sure of the time frame, but you would be correct. I think it aligns with freight companies which don't need to keep a register of everything that moves through their depot. I imagine that job if they did!!

Try soaking them. If it is too stuck I don't bother. The cost of new ones isn't worth the effort

Re: chemical register
Consumer products are domestic products that are purchased in small quantities from say, a supermarket or hardware store. They do not need to be added to a register even if they are hazardous. Once you start buying these products in bulk e.g. by the carton, they do need to be added to your register.

Re: Amber dropper bottles
I have an ample chem store so my droppers are stored in there. In Unitrays and with the DG class of the solid/concentrate.

Re: Amber dropper bottles
I think they just copy previous experiments without thinking too much about what they need. Limit supply and they'll adapt. Probably, my first port of call would be to let the teachers know you are streamlining. Most of them won't say anything so you can go ahead and wait for the tears later

Re: Amber dropper bottles
Regarding the concentrations of acids, we generally have 0.1M and 1M in droppers. I do also have 2M HCl in droppers. A coincidence that I read this now as I've just emailed a teacher who wanted 0.5M solutions (at short notice) telling him he could have 0.1M and in future if he wanted 0.5M I would or...
