Some advantages offered by the conceptual schemes of the irreversible processes thermodynamics in analysing different dissipative phenomena are summarised. The explicit time dependence of all variables and the introduction of new concepts such as the generalized fluxes and forces are the focus of a didactic approach which has been submitted to secondary school students.

The following contribution to the last AIF’s Congress outlines a concise didactic excursus on stellar evolution suitable for secondary school students. The proposal, following Galileo’s suggestion about the “book of the Universe”, invites to get the relevance of the study about the origins and of an evolutive process resulting in our very existence.

The difficulty that is attributed to electrostatic experiments and the little favour that these hold among many teachers generally lies in not knowing the electric properties of the materials in the conditions in which the experiments are intended to be carried out: high tension and a very small electrical charge.
