Adhesives Teaching Unit Henkel（德国汉高粘合剂教学单位）.pdf

Adhesives Teaching Unit Information for teachers These materials are based on a one-week research course for elementary school students, which is part of the “Forscherwelt” or “Research World” education initiative. They supplement the student worksheets and provide additional information about the materials required. They are also intended to help with lesson planning. The teaching concept and program were developed under the guidance of Prof. Dr. Katrin Sommer, Chair of Chemistry Didactics at Ruhr University Bochum, Germany, with the support of Henkel adhesive experts. The experiments are suitable for third or fourth grade students. Prof. Dr. Katrin Sommer, Chair of Chemistry Didactics Adhesives teaching unit Concept for 8-9 double periods of science Introduction Adhesives and adhesive technology have long been an integral part of both normal daily life and industrial manufacturing processes. Adhesive products range from simple craft glue to industrial superglues that can be used to adhesively bond entire airplane wings. This Adhesives teaching unit is designed to introduce children to the world of adhesives. Firstly, they gain an initial insight into the wide variety of adhesives and applications; secondly, the example of an adhesive with which they are familiar is used to teach them how and from what adhesives can be produced. The unit also provides the opportunity to explore phenomenologically the question of why adhesives are sticky.
