What is the CMS Physics Masterclass?



The CMS Physics Masterclass provides an opportunity for high-school students and their teachers to explore the world of Particle Physics in one day or less! They are invited to take part in an authentic research process, either at a nearby CMS institute or at school. Lectures from active scientists give insight into methods of basic research, enabling the students to perform measurements on real data from the CMS experiment at the Large Hadron Collider (LHC). Like in an international research collaboration, the participants then discuss their results and compare with expectations. The CMS Masterclass offers students the chance to close their textbooks and experience modern science first-hand! It also provides excellent support for teachers with material on Particle Physics. Watch the video with students and teachers, who explain their motivation for participating and what they gained from the CMS Masterclass.
