Advertising for consumer goods often incorporates slogans that draw a clear line between the advertised goods and "chemistry" and leverage the positive image of "nature" (Gröger, Krischer & Spitzer, 2014; Schummer, 2017). However, even if cleaning products, medicines, cosmetics or food do not contain synthetic chemicals, their desired effect is brought about by chemical ingredients. The ROSE study, for example, showed that such slogans have an impact on society (ROSE: The Relevance of Science Education). In the study, which was conducted on a subsample of 15-year-old Germans, about 65 % of the girls and 50 % of the boys considered science to have more harmful effects than benefits (Sjøberg & Schreiner, 2010). In contrast, themes presented in the context of "nature" give rise to romanticised ideas in society. The youth report "Nature" (Jugendreport Natur) called this phenomenon the "Bambi syndrome" because nature is generally regarded as harmonious and beautiful, but also as threatened and in need of help (Brämer, 2006). Overall, therefore, public opinion is shaped by an antagonistic view of "chemistry" and "nature". The layman is seldom aware that chemistry as a natural science serves to describe nature by explaining chemical substances and the changes they undergo during reactions. Chemistry takes place everywhere, especially in nature. This is exactly what makes the teaching concept "Natural Chemistry-Teaching Outdoors" (CHEMIE PUR-Unterrichten in der Natur) so relevant. The core idea of Natural Chemistry is to move selected chemistry lessons outdoors into nature. Students carry out experiments outdoors on substances collected there in order to understand environmental processes. Outdoor education in a natural learning environment, as part of the school curriculum, can foster interest in learning (Waite, Bølling & Bentsen, 2015; Becker, Lauterbach, Spengler, Dettweiler & Mees, 2017) and promote a more positive attitude towards the environment (Stern, Powell & Hill, 2014; Becker et al., 2017). In addition, contact with nature, especially when accompanied by others, and enjoying time spent in nature are essential factors that enable an individual to con
