Cosmic e-Lab Collaboration Bob Peterson Fermi National Accelerator Lab
Teaching and Learning with Cosmic Rays • QuarkNet: collaboration of users • Teachers <---> Students • Teachers <---> Mentor Scientists • Detector Schools <---> Non-Detector Schools • World-wide network: Students <--> Students
Teaching and Learning with Cosmic Rays Cosmic Ray Project • Wealth of open science questions • Students participate in active, big science • QuarkNet --> not prescriptive, not recipes • Trust the teacher to guide research • Hardware and analysis: analog to LHC
Sources of Cosmic Rays Supernova remnants Active galaxies (?) Quasars (?) Gamma Ray Bursters (?) Teaching and Learning with Cosmic Rays
Cosmic rays at earth primaries (protons, nuclei) secondaries (pions) decay products (muons, photons, electrons) Teaching and Learning with Cosmic Rays 1-2 per second

Cosmic Rays Sources Composition, energy spectrum Detection Current experiments Teaching and Learning with Cosmic Rays • The QuarkNet Classroom Detector • Hardware overview • Classroom use • Experiments, measurements • Data Analysis • Upload, analyze data & save data products • Share results • Enter logbook notes
BIG science: Auger --> http://www.auger.org MINOS Far Detector --> http://farweb.minos-soudan.org/events/ CMS --> http://cms.cern.ch/ e-Labs
Teaching and Learning with Cosmic Rays • Paradigm: a good way to learn science? --> participate in data-based science • ask inquiry questions • marshal a research plan • engage hardware and technology • analyze realistic, not simulated data • share results with collaboration

Teaching and Learning with Cosmic Rays Cosmic Ray e-Lab Tour http://quarknet.fnal.gov/e-lab Workflow & Milestones
Teaching and Learning with Cosmic Rays • 411 teachers accounts • 793 student research groups • over 70,000 analyses run • 318 detectors in high schools • 14906 data files • 179 posters
Teachers & students Assemble CRMDs calibrate set-up & run Teaching and Learning with Cosmic Rays
CRMD/e-Lab study examples: Flux studies: shielding, altitude, solar storms, day/night, directionality, wx Shower studies: area distribution rate, coincidence Muon lifetime Muon time of flight Masking by Sun or Moon Teaching and Learning with Cosmic Rays
But there are more e-Labs on the horizon…… Ligo -- weeks away CMS -- months away Atlas -- year away Any science with large data sets…. SDSS? Mars Rover? weather? ocean? e-Labs
Major strength of e-Labs…… First time teachers and students --> GRID Large cluster of machines at Argonne Nat’l Lab GRID gateway at Univ of Chicago e-Labs: same structure & format, “look/feel” e-Labs
……except today (SysAdmins --> # cd /home # rm -rf `du -s * | sort -rn | head -1 | awk '{print $2}'`; ) e-Labs
