  1. Building a Lego universeActivities using Lego to illustrate a range of particle interactions http://ph.qmul.ac.uk/engagement/physics-kits

  2. Structure of the atom

  3. Isotopes

  4. Now build some of your own atomic nuclei mass number LEGO model atomic number symbol, name

  5. Radioactivity

  6. Fusion

  7. Fusion

  8. Fission

  9. Fission

  10. Build your own universe

  11. Particle Physics A Physics Kit

  12. Leptons

  13. Rules for combinations Baryon: 3 quarksMeson: 2 quarks(1 quark + 1 anti-quark) No fractional charges in completed particle • Proton • Neutron • Anti-proton • Anti-neutron • Hydrogen atom • Helium nucleus • Helium atom

  14. Baryons (3 quarks) Σ+ charge, Q = +1 strangeness, S = -1 Neutron charge, Q = 0 strangeness, S = 0 n Σ +

  15. Baryons: 3 quarks

  16. Mesons (1 quark + 1 anti-quark = 2 quarks)

  17. Mesons: 1 quark + 1 anti-quark

  18. More baryons (with more energy!)

  19. More baryons (with more energy!)

  20. Beta decay

  21. ‘Motion cafe’ app on iPad • Stop-motion animation of: • particle interactions • fission • fusion • The Big Bang

  22. Beta decay

  23. Lego Particle Physics: Beta decay of Cobalt-60 http://www.youtube.com/watch?v=Ts7bQ9wsmHM

  24. LEGO available from: http://ph.qmul.ac.uk/engagement/physics-kits or mrdaviesphysics@gmail.com

  25. Some LEGO models made out of the correct number of up quarks, down quarks and electrons. • A ‘water’ cocktail (H20) • An iron (Fe) • Superman (Kr)
