Από το μακρόκοσμο στο μικρόκοσμο - Από τις φυσικές ιδιότητες στις διαμοριακές δυνάμεις

Abstract

In this teaching proposal, students examine the existence, strength and type of intermolecular forces that develop between the molecules of specific liquids. The proposal is based on the effects that intermolecular forces have on the physical properties of substances and is implemented in the science laboratory during the teaching of the chemistry lesson of the first grade of the General High School. The duration of the proposal is two teaching hours, where the students are put together in groups of 3-4 persons. The choice of class A is made because intermolecular forces are taught immediately after chemical bonds, as provided for in the new curriculum.
