Australia's Science Forum

Hi all, Just wondering if any of you have been asked to do a chemical stocktake for the entire school? Or do you just record science? I've been trying to find some information on this but can't find anything other than forums but I have read somewhere that you don't need to record the chemical if it...

May I have a copy please too?

Wonderful, thanks Labbie

Hi
this might be a dumb question, but I followed the instructions in 'the laboratory', so when the solution settles am I meant to decant that liquid into a bottle? or just do it now when its a milky colour?

thanks!

I didn't get to it yesterday so it sat in the fume cupboard overnight thankfully!
Thanks Merilyn

Amazing, Thank you

Hi sorry to post, I tried looking for a similar post and I couldn't find one,

A teacher has made a carbon snake with concentrated sulphuric acid and sugar.

How do I dispose of this??

Thank you

Heya.
If using the dropper trays (or any trays), does the agar come out easily enough or does it stick to the edges?

Thanks

Hey,
Just wondering. I've had the eggs in from the beginning of the day, how long does the process usually take to complete?
And is it bad if I leave them in the fridge still in the vinegar over the weekend to complete? Or will this just further break them down?
Thanks!
