Università Roma Tre

1. Analyzing the conceptual basis of modern Chemistry comparing the ancient vision of matter as a compound of four elements with the discovery of the Periodic table of elements, the concepts of molecule, valency, and chemical reaction.
2. Presenting the first ideas about chemistry from a superior point of view: states of matter and their transitions, solutions, the geometric structure of crystals, some elements like metals, oxygen, hydrogen, and chemical composition of substances.
3. Deepening the fundamental aspects of the methodology for teaching Chemistry to children: observing objects and substances, the microscope, laboratory experiments, questioning further than candid ideas, the dialogue with the teacher and among peers, and the ability of accounting for scientific information.
