"Stimmt die Stimmung? Physik am Klavier" lautet das Thema der Besonderen Lernleistung (BeLL), die David Hahn am Chemnitzer Johannes- Kepler-Gymnasium erarbeitet hat und mit der er am 27. und 28. Februar 2009 beim südwestsächsischen Regionalwettbewerb von "Jugend forscht" antritt. Sein Betreuer Dr. Hans-Gottfried Hempel vom Institut für Physik ist einer von mehreren TU-Wissenschaftlern, die ihren Schützlingen an diesem Wochenende die Daumen drücken. "Vom Kepler-Gymnasium nehmen fünf Projekte am Regionalausscheid teil - alle Schüler werden an der TU Chemnitz betreut", erzählt Joachim Schwind, Lehrer und Verantwortlicher für die BeLL-Arbeiten des Chemnitzer Gymnasiums.
