Course abstract

The course consists of two parts - physics and meteorology. This includes lectures, laboratory work and unassisted studies. Physics gives an understanding of the conditions necessary for the existence of biological objects: water, heat, gas exchange and light. The Meteorology shall provide knowledge of physical processes in the atmosphere which determine weather conditions and growth conditions.

Learning outcomes and their assessment

After completing the course, students will have:
knowledge of the regularities considered in the course of physics and critical understanding of their applicability to describe real processes considered in their specialty (2 tests);
skills to perform measurements of physical quantities and perform calculations in the research of their field, to summarize and analytically describe the results (8 laboratory works, their calculations);
competence to evaluate the results of measurements and calculations, to look for solutions to problems (defense of 8 laboratory works).

Requirements for awarding credit points

The exam must be passed. Conditions for taking an exam:
1/ Meteorological part, is required to collect 50% of the maximum possible score, summing up the score; tests in theory (maximum 2 x 10 p) and average evaluation of laboratory works (maximum 10 p);

2/ In the physics part, it is necessary to collect 50% of the maximum possible score by summing up the score; tests in theory (maximum 2 x 10 p) and the average score of laboratory works (maximum 10 p).

Description of the organization and tasks of students’ independent work

1. Study literature independently according to the course plan.

2. Laboratory work should be processed and counted.

Criteria for Evaluating Learning Outcomes

The overall assessment in the course is determined as the weighted average of the grades obtained from the Physics and Meteorological Parts.
A student can obtain a successful mark for a test or exam if he / she collect at least 50% of the points in the assessment.

Students who have acquired at least 60% of the maximum possible score during the entire semester can receive an accumulative score.
