High school students use cutting-edge tools to do scientific investigations.

Particle physics aims to answer two questions: What are the elementary constituents of matter? What are the fundament forces that control their behavior at the most basic level? CERN's Large Hadron Collider (LHC) and its experiments will probe deeper into matter than ever before. The Compact Muon Solenoid (CMS) detector is designed to detect fundamental particles: electrons, muons, tau leptons, photons, and quark jets and missing energy due to very weakly interacting particles such as neutrinos. Massive particles such as the Higgs boson will decay into these fundamental objects, the properties of which will be measured in the CMS detector's many subsystems.

The CMS e-Lab provides students with an opportunity to analyze data to calibrate the detector and participate in discovery science (as particle physicists do). Calibrating the detector to "rediscover" previous measured results is an important part of the early scientific activity at CMS. Later students will probe data where physicists expect to find answers to questions at the heart of 21st century particle physics. The CMS e-Lab addresses ALL science practices in the Next Generation Science Standards.
