Today there are various requirements for a modern chemistry class. It is not enough to teach special knowledge, students have to be led in their personal development and thus special skills and competences have to be trained in school as well. Therefore having well structured and efficient classes is a prerequisite. Basic concepts are defined, which should help to structure the chemistry classes thus enabling students to learn efficiently. One of these concepts is the concept of structure and properties. Structural features are directly linked to properties of a certain compound. In the majority of cases this interplay between structure and properties is discussed using simple organic molecules such as alkanes. However, in this study polymers were selected to study their potential application as model compounds for clarification of the structure and properties concept. Polyethyleneglycols (PEGs) were identified as promising candidates for context oriented chemistry classes. They have a broad area of application starting from pharmaceutical and cosmetic applications, to food chemistry, medicine, biochemistry, construction industry, or new technical applications. Thus PEGs are prevalent in every student?s daily routine and therefore of high interest. PEGs are available with various average molecular masses making them ideal samples for the study of melting behaviour. Moreover, polyethyleneglycols are easily soluble in water and thus good candidates for the evaluation of water solubility. This study showed that polyethylenglycols and other polymers are ideal candidates for the evaluation of the interplay between molecular weight and melting temperature and the molecule?s structure and the solubility in various solvents. Since PEGs and other polymers are omnipresent in all our lives students can be easily motivated for the topic leading to enjoyable classes with good learning results.
