Abstract

Some spectacular and useful demonstrations of chemistry. In this article, practical chemistry experiences which I implemented in my upper-secondary classes in Switzerland are presented. The chemical reactions described in this work and the way of presenting them to students, have shown to be useful and help to motivate students to learn chemistry. Pupils had to make the reactions, take notes of their observations and calculate some quantities. In this paper the students expected answers are presented.
