In the context of the year of chemistry from elementary school to university, the CNRS organized a national event involving conferences and the visit to CNRS laboratories. We had the pleasure to welcome high school chemistry teachers from the whole Alsace region to explain our researches and to show our equipment. This has been a good opportunity to discuss and exchange around our love for chemistry. The teachers have been welcomed by our director Dr. Frederic Leroux,  Dr. Joanna Wencel-Delord from SynCat, Dr. Mourad Elhabiri from CBM, Dr. Morgan Donnard and Dr. Armen Panossian from COHA and Matthieu Chesse from the analytical platform.
