The present thesis deals with students conceptions of the Nature of Science and their possible change after a visit to a student laboratory. The student lab, dealing with electromagnetic radiation, was designed and surveyed with regard to students conceptions within the project “JungforscherInnen auf den Spuren des Nichtwissens”.Studies about students conceptions, the characteristics of the student lab as an extracurricular place of learning and the aspects of Nature of Science form the theoretical basis of the study. At first, the learning materials, which were designed for this student lab on the topic of electromagnetic radiation, were evaluated. Thereafter they were adapted, finalised and used for the two holdings of the student lab. Using a questionnaire, the students conceptions were surveyed before and directly after the intervention (n = 36). The survey consisted of the Draw-A-Scientist-Test (DAST) and parts of the Views About Sciences Survey (VASS).The students image of a scientist was rather stereotypical (male, wearing glasses and a lab coat) at the pre-test. The number of stereotypic characteristics slightly decreased for the post-test. The distribution of the VASS categorisations according to gained points corresponds for the most part with the numbers of previous studies. An increase in adequate perceptions of the Nature of Science is not evident. However, this is consistent with previous studies, which showed that a one-time visit of a student lab cannot significantly change students conceptions.
