2. 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

3. 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

4. Sources of Cosmic Rays –Supernova remnants –Active galaxies (?) –Quasars (?) –Gamma Ray Bursters (?) Teaching and Learning with Cosmic Rays

5. Cosmic rays at earth –primaries (protons, nuclei) –secondaries (pions) –decay products (muons, photons, electrons) 1-2  per second Teaching and Learning with Cosmic Rays

9. 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

10. Teaching and Learning with Cosmic Rays Typical QuarkNet Detector Setup 1. Counters-scintillators, photomultiplier tubes (two shown) 2. QuarkNet DAQ board 3. 5 VDC adapter 4. GPS receiver 5. GPS extension cable 6. RS-232 cable (to link to computer serial port) 7. Optional RS-232 to USB adapter (to link to computer USB port instead of serial port) 8. Lemo or BNC signal cables 9. Daisy-chained power cables C osmic R ay M uon D etector

11. Hardware measures –light pulse timing –ambient temperature –atmospheric pressure Experiments include –Flux studies –Time correlation –Shielding –Particle speed –Particle lifetime –Altitude attenuation Teaching and Learning with Cosmic Rays

15. Teaching and Learning with Cosmic Rays Cosmic Ray e- Lab Tour http://quarknet.fnal.gov/e-lab Workflow & Milestones

16. 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

17. Teachers & students –Assemble CRMDs –calibrate –set-up & run Teaching and Learning with Cosmic Rays

18. – 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

19. 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

20. 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

21. ……except today (SysAdmins --> # cd /home # rm -rf `du -s * | sort -rn | head -1 | awk '{print $2}'`; ) e-Labs
