Re: Lab training
Hi melsid,
the link did work(thought it was for DET schools) and I had a look around. It seems its more teacher orientated than lab assistant.
Thank you for offering your suggestion.

Re: Broth for Pasteur experiment
Hi Bigmac,

I just add a teaspoon of vegemite in water and shake.

we placed it in front of the window.
