## Learning objectives

The course has been designed to provide fundamental concepts indispensable for understanding the mechanisms and the laws that rule the nature and that underlie the properties of matter, with special emphasis on those aspects useful in the comprehension of chemical and biological processes to better understand the concepts necessary to some of the following biology and chemistry courses. In addition, the course want to give the ability to formulate and solve the problems.

## Prerequisites

## Teaching methods

Oral lessons in which the topics of the classic physics reported in the section “Contents” will be presented and explained. The arguments will be completed by several examples and exercises to the aim of understanding the possible applications of the explained concepts.

## Assessment methods and criteria

Written exam in which both the resolution of problems and the answer to questions about the fundamental physical concepts and principles explained in the oral lessons will be required.

The students can improve the final evaluation with an oral exam.

## Other information

The course takes part in the IDEA Project, benefitting by the help of a high school teacher that, in a dedicated time, will go thoroughly into the exercises and problems.
