Abstract This contribution describes the course “Discovering cosmic rays” for inservice high school physics teachers, organized in the context of the Italian Plan for Resilience and Recovery (PNRR) “CTA+” program. Proposed as part of the OCRA (Outreach Cosmic Ray Activities) activity, the 3-day course was held at Laboratori Nazionali del Gran Sasso (LNGS) of the National Institute of Nuclear Physics (INFN) in Italy in December 2023. The teachers built a compact and effective muon telescope in the laboratory, the Cosmic Ray Cube (CRC), designed by LNGS-INFN. After a lesson on data analysis and measurement of atmospheric muon flux, the teachers developed original educational pathways, creating a concrete output ready to be implemented in the classroom.
