The 1st ESO group has completed the chemistry period where they have experimented in the laboratory with chemicals and also everyday products to produce chemical reactions that have allowed them to discover how combustion and other simple chemical processes work. From the realization and observation of chemical reactions such as combustion, formation of different gases and use of acidity indicator substances, they have been measuring and using different laboratory materials and instruments. The story of Antoine Lavoisier’s life has also accompanied us during these 4 weeks in which the students have experienced what the father of modern chemistry had to face in his research during the French Revolution.
