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.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 Track Activity Worksheet Bubble Chamber Student Analysis.

10. Objective Develop a “template” that you can use with your students to evaluate any of 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. FAQ Presents 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?
