## 20410240 - FISICA

Provide a good basic knowledge about The Concepts, Laws and Principles of Physics, particularly with regard to topics related to the degree course in Biological Sciences.
Develop the skills to apply these Laws and Principles for the quantitative interpretation of real phenomena, with particular regard to the specific aspects of the degree course in Biological Sciences and the professional expectations of a future Biologist.
The course, with mandatory attendance, includes theoretical lessons, exercises and practical activities. Practical activities will use, as far as possible, materials and tools that are easily available so that they can be reproduced independently of students.

Type of delivery of the course

Lessons in classrooms

Attendance

Attendance is compulsory in presence. Some activities are only available to those who regularly attend the Course. Some assessments may only be available to students attending regularly the course . Following the authorisation of the Teaching Board, the lecturer will make streaming and recorded lectures available for those topics and procedures that are more difficult to memorise and follow (algorithms, procedures, etc.).

Type of evaluation

Attendance is compulsory, attendance is recorded on a spot-check basis, and admission to some examination or test sessions may be conditional on attendance of at least 70 per cent. The examinations consist of - a written test with multiple-choice QUESTIONS to check basic knowledge (20 questions on the topics of the Fisica-Zero course) - a written test with multiple-choice QUESTIONS (40 questions on the topics of the Physics course) - an oral interview in which the following are assessed: knowledge of the laws and principles of Physics covered in the course the ability to model real phenomena (in particular those involved in the Biological Sciences degree course) using principles and laws of Physics and to argue the choices made; the capacity to recognise the physical parameters involved in a phenomenon, make approximations, estimate/calculate the quantities used; the appropriate use of scientific language and physics concepts to discuss the models used in a quantitative manner and to critically analyse the results obtained. Self-assessment tests are available throughout the course to enable students to test their acquired knowledge and skills. The results of the Self-Assessment Tests do not count towards the exam result No exemption tests (Esoneri) are provided during the course .
