Learning outcomes:
General Chemistry:
After successfully completing this module, students will be familiar with the essential basics of general chemistry, consisting of atomic structure, the periodic table of the elements, chemical bonding, states of aggregation and chemical reactions. They will understand the connection between the electron configuration of the atoms, the structure of the periodic table and the properties of the elements derived from it. They will be able to describe the chemical bonding of substances, prepare molecular formulae and, in the case of covalently bonded substances, also the structural formulae, and derive structure-property relationships - incl. taking into account van der Waals forces and hydrogen bonds, if required. Students will be familiar with the basic principles of chemical reactions (reaction equation, stoichiometry, equilibrium, redox and acid-base reactions) and can apply them in order to interpret simple chemical processes. This includes the use of simple, chemical calculations.
The "General Chemistry" module element will increase and improve students’ professional competence.
Chemistry Lab:
By means of experiments, students will independently experience and learn about the basics of general chemistry while working with partners. They will be able to set up and perform elementary, chemistry experiments. Based on observations and existing knowledge, they will be able to derive conclusions and link them to the contents of the lecture "General Chemistry" (= reflective thinking and learning). In addition, students will be able to prepare laboratory reports/experimental protocols, the structure of which is usually divided into topic/question, assumption, materials used, experimental set-up and execution, observation with measured values and evaluation (interpretation, explanation, interpretation, error analysis, if necessary).
The chemistry lab aims at expanding and improving the students´ instrumental and communicative competence.
Experimental Physics:
Students will be familiar with the scientific principles of the dynamics of a single mass point and systems of mass points. They will be familiar with the basic terms, phenomena and concepts and understand the physical relationships. This knowledge will enable students to reduce simple engineering problems to basic physical principles or questions, to answer these physical questions independently using mathematical methods, and thus, find a solution to the actual engineering problem in a targeted manner.
The "Experimental Physics" module element is designed to expand and strengthen subject-specific and instrumental competence as well as to develop the systemic competence to solve problems taking into account scientific-technical, ethical, societal and ecological issues.
Physics Lab:
By means of experiments, students will independently study the essential physical principles of the mechanics of rigid and real (liquids, gases) bodies, as well as waves, optics, atomic and quantum physics. They will be able to set up basic, physical experiments, carry out series of experiments and measurements and evaluate them, taking into account the calculation of errors. In addition, they will be able to prepare laboratory reports/experiment protocols, the structure of which is usually divided into topic/question, assumption, materials used, experiment set-up and execution, observation with measured values and evaluation (interpretation, explanation, interpretation, error analysis, if necessary).
The physics lab is designed to expand and strengthen students’ instrumental and communicative competence.
