General chemistry experiences with children

Posted by: @marie-curie

Hey! have you ever worked as a chemist (chemistry teacher, for example) with children? share your experience. I am interested in what experiences can be shown to children so that it is spectacular and beautiful, but at the same time completely safe. and I would really like to collect ideas other than the well-known "volcanic eruption"

Hello, for example growing salt crystals, silicate garden, colored precipitates, Liesegang rings, crystallization of supersaturated solutions like sodium acetate

Hello! I agree with @nanoserebro, the experiments are quite bright and not very difficult to perform. If the children are very young, you can even make a simple "chemical rainbow" and just get colored solutions

@nanoserebro great ideas, thanks! I really like silicate garden

Was glad to help!

I remember that one of the most fun experiments I've done in my hole practice is burning sulfur in KClO3. Maybe it's not that safe, but it's a very good work for high school

@amalgama thank you for an idea) 

I strongly doubt that there is Berthollet salt in school laboratories at all)

@argentum Maybe a really old, scary and uncertified one))

@amalgama Bertofos for  e.g.)

@argentum What's that?😅

@amalgama mixture of P+KClO₃
