To understand the topics of the course and to perform the practical activities, students are required to possess the following competences, acquired during the Maths course of the first semester:
 basic notions of maths (algebra, trigonometry, differential and integral calculus)
 basic notions of statistics and data analysis (data taking, distributions and statistical properties, random variables, data analysis on a PC)
 capability of interpreting the plot of a function
The assessment requires several steps:
 during the course  part 1: students will be assigned four assignments consisting in the analysis of videos concerning the physical phenomena treated in class and in the writing of short reports containing the description of the phenomenon, the data analysis and the conclusions. The activity can be performed individually or in a group (made up of a maximum of three students). For each assignment there will be a deadline for delivery and the student/students will have to implement the corrections indicated by the teacher.
 during the course  part 2: students will be offered the opportunity to participate to four exercise verifications in which they will have to solve exercises at home as done during the exercise sessions in class; the exercises will be sent via elearning and a maximum delivery time will be given. The exercises can be solved individually or in groups (which must be the same as the assignment group).
 at the end of the course  oral exam:
* those who have delivered the assignments and the correct exercises on schedule can access the oral exam by choosing one topic among those treated during the course
* those who have completed the assignments but not the exercises can access the oral exam bringing a topic chosen among those treated during the course and will also be asked the physics of one of the assignments chosen by the teacher
* those who have not completed the assignments within the scheduled time, in the first part of the oral exam will have to solve three exercises on the blackboard; the exercises will be of the type solved during the exercise sessions. If the exercises are carried out correctly, the student can proceed with the oral exam choosing one topic among the ones of the course.
The three verification phases have different goals:
 part 1 intends to verify the ability to describe the physical phenomenon, to analyze experimental data and to comment critically on the results comparing them to what expected
 part 2 intends to verify the ability to critically apply what has been learned, during lessons and during the assignments, to concrete problems, adequately describing the logical path that led to the solution
 the oral exam intends to verify the level of knowledge acquired by the student on the topic under discussion, his/her ability to describe and analyze it with an appropriate language and his/her ability to decline it in different contexts.
The verification phases during the course do not contribute to the final grade but allow the access to the oral exam; in the event that the assignments have not been carried out, the student can access the final part of the oral exam only after having successfully solved three exercises on the blackboard.
To pass the oral exam, the student must present the chosen topic satisfactorily, with an adequate language, demonstrating a satisfactory understanding of the physical phenomena and the theory that describes them.
The value of the final grade will depend on the student's ability to answer questions on the topic.
Full marks with laude will be awarded to the student who proves he/she has an excellent understanding of the subject and the ability to apply the physical laws of that field to problems of reality not discussed directly in class.
The goal of the course is to provide students with concepts and instruments to observe and understand natural phenomena, insert them in the physical laws frame, represent in a graphical way the variables that describe the phenomena and analyze critically this representation. The course contributes to the learning outcomes of the Degree Course, developing the capability of: observing and interpreting the physical phenomena using also mathematical and statistical concepts; evaluating experimental data in a critical way; integrating the competences acquired in different field to apply them to the solution of new and interdisciplinary problems.
At the end of the course students will be able to:
 observe natural phenomena framing them in the context of physical laws
 solve autonomously simple physical problems representing the results in a graphical way to understand the relation between quantities
 analyze the data collected in simple experiments, writing short scientific reports that describe the phenomena, the data analysis and the obtained results
 use programs of data analysis that allow to represent the collected data in a graphical way and to perform a fit of the experimental data starting from a theoretical prediction.

Students are provided with the slides of the lessons and dedicated material when necessary (articles, notes).
The course is divided into:
 frontal lessons (32h) during which the teacher will use stimulus questions to face the different areas of physics. These questions will allow to organize paths that demonstrate how the same laws are able to explain apparently different phenomena; the starting point for these questions will be as much as possible related to the field of study of the Degree Course. Each path will include small experiments, when possible, performed in the classroom with low cost materials.
 exercise sessions (24h) during which:
* the teacher will explain exercises that allow a critical application of what seen during the lesson and require the graphic representation of the variables involved in the physical phenomenon, with a critical evaluation of the result
* the students will perform the analysis of the experimental data collected in the form of videos of some of the phenomena treated in the lessons. These videos, provided by the teacher, will be analyzed using the open source Tracker software, which will be installed on the students' portable PCs so that they can work directly in the classroom. If the analysis cannot be performed with Tracker, the Excel software will be used. This part of the activity will allow students to practice to be able to perform the assignments for the final assessment.
