Courses, Learning and Teaching Methods and Literature
Courses and Schedule
Learning and Teaching Methods
The module consists of a lecture, a tutorial and a lab course.
Lecture: ex-cathedra teaching with demonstration experiments
Exercise to Physics for Life Sciences: students get problem sheets and try to solve these problems by themselves or in small groups in the first part of each tutorial session. After this phase sample solutions are presented by students or the lecturer and also possible alternative ways to solve to the problems are discussed. Students who present at least two solutions per term during the tutorial can get a bonus of 0.3 on the grade of the module. Following these tutorials will help the students to be prepared to solve the problems during the written exam.
The lecture and the tutorial are closely intertwined and the lecturers are in constant exchange.
The lab class consists of a training phase and a practical exam. During the training phase in the lab students perform and describe seven different experiments, one of them is repeated in a slightly modified way on the day of the practical exam. The students work in small groups of two to three persons when carrying out the experiments and writing the lab report together. The students need to have performed all seven experiments and have successfully written all lab reports, which have to be positively rated by the tutor.
During the lecture a powerpoint presentation is used and some contents are explained using the blackboard. Additionally some example videos and experiments are shown during the lecture. For the exercises problem sheets are prepared. An e-learning course in Moodle exists. Presentation slides and problem sheets as well as sample solutions to problems which have already been discussed in the tutorials are available on this platform.

Description of exams and course work
The module exam consists of two parts. There will be a written exam of 90 minutes duration on the learning outcome from lecture and exercise. The skills and knowledge obtained in the lab course are tested in a lab exam with a written and graded lab report. The lab exam has a total duration of 240 minutes and contains the execution, documentation, analysis, and discussion of an experiment as well as the written answer to questions on the physical foundations, implementation, and setup of the experiment. The grade of the module exam is calculated from the partial grades with 4/7 of the written exam and 3/7 of the lab exam.
For example an assignment in the written exam might be (the exam is in German language): Ein Hochstrahlbrunnen spritzt das Wasser bis in eine Höhe von 140 Metern über der Düse. a) Berechnen Sie die Geschwindigkeit v0 (in km/h), mit der das Wasser aus der Düse strömen würde, wenn keine mechanische Energie verloren ginge. b) Berechnen Sie die Geschwindigkeit v1 (ebenfalls in km/h) des Wassers in halber Höhe. c) Erläutern Sie, warum der tatsächliche Wert der Geschwindigkeit des aufsteigenden Wassers mit ca. 200km/h für v0 über dem berechneten Wert liegt. d) Berechnen Sie welche Höhe die Fontäne erreichen würde, wenn v0 nur halb so groß wie der in Aufgabenteil a) berechnete Wert wäre. e) Pro Sekunde durchlaufen die 500 l Wasser die Düse. Untersuchen Sie, wie lange die Fontäne mit einer Energie von 10.000 Kalorien betrieben werden kann.
In the written exam the following learning aids are permitted: pocket calculator, hand written formulary (i.e. hand written notes on a sheet of the size A4. No copies.).
Participation in the exercise classes is strongly recommended since the exercises prepare for the problems of the exam and rehearse the specific competencies.
There will be a bonus (one intermediate stepping of "0,3" to the better grade) on passed written exams (4,3 is not upgraded to 4,0). The bonus is applicable to the exam period directly following the lecture period (not to the exam repetition) and subject to the condition that the student passes the mid-term of presenting at least two sample solutions to the problems to the group.
There is a possibility to take the exam in the following semester.
