HEP in Greek Classes

The HEP (high energy physics) Inquiry learning resources created over the last four years by the European outreach projects are reviewed. The resources are mostly addressed to high school students and the purpose is to ignite their interest on science. In addition, at the University of Athens for the last four years we have been using the HYPATIA on-line event analysis tool as a lab course for 4. year undergraduate physics students, majoring in HEP. Each year 40-50 students highly appreciated the course, since they get a direct involvement in the actual top-level research. Up to now, the course was limited to the visual inspection of a few tens of ATLAS events. Recently we have enriched the course with additional analysis exercises, which involve large samples of events. The students, through a user friendly interface can analyze the samples (both signal and background ones) and optimize the cut selection in order to search for the Higgs decay H → 4 leptons. Recently ATLAS released 1 fb^-1 of data, so starting now the students analyse real data. (authors)
