Presentation Transcript

  1. Bubble Chamber Website Shane, Per, Peter, Szilvia, Luminita, Inger and Claude.

  2. Outline of B.C. Presentation • Introductions, motivations – Shane • Improvements in tutorial – Inger • Example exercises – Luminita/Per • FAQs/Lessons – Peter • Gallery improvements – Claude/Szilvia • Summary – Shane

  3. “Catchy” Questions • Interested in “seeing” the invisible? • Want your students to make their own observations and analyses, much like a scientist? • Want to know more about what is happening in modern physics research? …Then studying bubble chamber pictures is for you (and your students)!

  4. Review/Apply Concepts • Conservation of energy • Conservation of momentum • Conservation of charge • Behavior of charged particles in a magnetic field

  5. Practice Various Skills • Pattern recognition—noticing patterns and deciding what events are “interesting” • Problem solving in physics, potentially using limited – non-intimidating – mathematics

  6. The Tutorial Minor improvements: • Fixed broken links. • Corrected mistakes. Major improvements: • Table. • Momentum and energy conservation. • Conservation of charge, baryon number and strangeness. • Exercises.

  7. Exercise 2 • Random order of question • Exercise 2

  8. Exercise 2, events • No electron spiral • Vee pointing to a kink • Two kinks • Symmetric vee

  9. Bubble Chamber Student Analysis. Bubble Chamber Track Activity Worksheet

  10. Objective • Develop a “template” that you can use with your students to evaluate anyof the bubble chamber pictures.

  11. Required Materials • Print out of bubble chamber photograph • Ruler • Coloured pens

  12. Required Background • Conservation of Charge • Conservation of Energy • Conservation of Momentum • Left Hand/Right Hand Rule

  13. Layout • Modular Format • Recreating the crime scene/ Scientific Method

  14. Investigating the Crime Scene • Looking for evidence → high lighting it! • Evaluating the evidence • Reconstructing the crime scene

  15. Reconstructing the Crime Scene • Measuring “event” time scales • Applying Conservation of Energy • Identifying daughter particles of decays • Identifying properties of the interaction particle

  16. FAQPresents Bubble Chamber FAQ for Teachers and Students

  17. Motivation • With an active website, there is now a need for a FAQ section. • For points where you (teacher) or students may get stuck in the tutorial.

  18. Example FAQ’S • How do I distinguish between a decay and a collision? • How can I determine the direction of the magnetic field if there is no knock-on electron? • What is the sequence of particle identification?

  19. Future Plans • Create the links between the Bubble Chamber Tutorial and the FAQ’s.

  20. Review • We now have a “tool” for our educational “tool box” for addressing the following: Interested in “seeing” the invisible? Want your students to make their own observations and analyses, much like a scientist? Want to know more about what is happening in modern physics research?
