Not sure if this is the right forum but my son has to write up on a chemistry experiment from 2 weeks ago. Something about holding a piece of gauze in a roaring bunsen flame. e.g. in the blue cone and above the cone then repeating with nichrome wire (?) in cork. He has record the results using diagrams and what happened, also write a conclusion.
Two weeks is along time to him and he is having difficulty recalling what happened. I know, he should have made notes at the time but I would like to talk him through this one so he knows what to do next time.
Is anyone familiar with this experiment?
