  Publication Details (including relevant citation   information):

  This paper reports the thermal decomposition of basic copper   carbonate and sodium hydrogen carbonate to be carried out by   first-year students of a technical institute or a lyceum. These   experiments provide reproducible results and are useful for   developing important steps of the learning process. Through these   experiments, some knowledges on chemical reactions can be   deepened, beyond the mass conservation law; moreover, the   critical examination of the qualitative and quantitative results   allows for correcting a wrong hypothesis, which is very common by   the students, that is chemical reactions have to be joined to   visible effects. Finally, a particular attention is given to the   use of materials which, after their manipulation, give rise to   recyclable products or to products suitable to easy disposal.
