The bachelor thesis deals with the interior greening of a classroom at the Ehrental Education Centre and the use of measurements to increase the motivation of students. The focus was on the factors well-being, concentration, air quality and the effect of colours. The experimental group consisted of 15 year old pupils and their teachers. Three narrative interviews and three group discussions were analysed qualitatively according to Bohnsack.
