Thanks Rowanne, I can't explain that they are not going to get large amounts of oil. Not listening and is continuing to keep trying different methods I think 1-2mls is pretty good. I feel like buying some esstential oils and adding to it! lol I don't know where she is getting the information now wan...

Hi,

I've been asked to ask the brains trust "Using ditillation to extract oils", from rosemary etc., what practical do you use?

Hi, it's FRIDAY!!!

Can anyone tell where I could purchase a 19/26 500ml short neck round bottom flask from? I've searched my normal suppliers with no luck.

Morning Brains Trust, How does everyone go about getting the kids to remove hot beakers full of liquid and tripods to put away? We generally let them cool for a few minutes while they are writing up results; then pack up. We have never had an accident. Does anyone use heat gloves? one stored at each...

Oh no

Another Tik Tok one I was told about during the holidays was RAT tests. Kids in the US are using cranberry juice to draw a second line on tests to show parents so they can stay home. How do they think of these things.

Thanks Bigmack it sounds like a winner. I'll give it a go next years.

Back in the 80's I worked in a commercial lab (fruit Juice), I came back from lunch and the pressure cooker had been used to make plum jam (YUK MICRO PLATES) the lid was embedded in the ceiling with plum jam from A to B. The Chemist just looked at my and laughed gave me the afternoon off, the guy wh...

We got these a few years ago from Haines had them mounted on the wall. I glued strips of artificial suede on the inside. 30 spaces

Haven't had a problem.

Hi Bigmack

That one is better than the one I have for Bromine in Situ. Does it hold it's colour or do you have to make up fresh each time?

This is another one I use, even the different styles of graph paper are good

Aparently another Tik Tok video of blocking toilets with boxes of tissues. Where do they get these ideas from. We are no longer handing out boxes of tissues.

Morning Everyone, These Stile pracs are doing my head in! And I agree with Merilyn1 about food wastage. There are days when I ask myself are we science or are we food tech! Next week we are going into Oreo Moon Phases... I ask you, do we really need to supply so many Oreo biscuits that we buy the s...

Anyone else having trouble with Chemwatch, I put a mini SDS out with each practical as required. I'm just going through my Chemical Register trying to update any that are 5 years out of date. Most of the SDS I'm looking at haven't been updated on Chemwatch majority out by more than 5 years 6 month n...

wow I wouldn't have thought it would be strong enough.

send in waste beakers marked with which chemicals, kids pour into there, then rinse. Anything that can't be comes back to me to clean up.

Same, all glassware is in prep.room ordered with pracs through RiskAssess. Kids have to rinse free of residue before teacher returns to prep. room. 90% of pracs go out on trollies our prep. room is central to labs. Bunsen, tripod, gauze, heat mat, retort stand, boss head, clamp and test tube racks a...

Thanks Merilyn I couldn't agree more, but you have given something else I hadn't thought of; Year 8 fine balance of ecosystems. Thanks It helps sometimes just to get another point of view. I'm sure they dream up some of these ideas without even thinking about how and why, just makes me out to be the...

Hi, Brains trust a quick question "I would say NO". We have a teacher wanting year 7 to bring into school insects etc., to dissect in class. When we re-did the dissection policies we added yr7 & 8 were not to use scalpels due to the amount of accidents that have happened, they pull apa...

4 gms in100 ml of water will do it. 4% cobalt (ll) Chloride is now 11-12 years. hope that helps

Just did this morning, RiskAssess custom label with "Unknown". Didn't have a problem, but don't edit them in Adobe DC Pro, just use as is.
