International Chemistry workshop of Clausthal-Zellerfeld

7th ICCW from 12 to 18 February 2023

The chemistry workshop is organized by the Faculty of Natural and Material Sciences of the Clausthal University of Technology (TU Clausthal) and the Robert Koch School and is aimed at English-speaking students in the upper school (primarily in the 12th year) who are interested in chemical issues, like to experiment and want to establish international contacts.

The schools addressed are those in other European countries with which the Robert Koch School has contacts, i.e. L'Aigle (France), Oborniki (Poland), Spisska Nova Ves (Slovakia), Slough (England), Trondheim (Norway ) and Freiberg in Saxony.

The chemistry workshop consists of

  • practicals and experiments
  • information and show lectures
  • excursions
  • as well as a varied supporting program
