![]() ![]() Classification of the different sorts of fundamental particles then leads to use of conserved quantities (some rather bizarre) to establish rules for particle reactions. The first topic deals with the fundamental particles that students have already met, and how their number proliferated in the second half of the twentieth century. They should be familiar with the ideas of conservation of mass, energy and electric charge. Students should know about the constituent particles of the atom (protons, neutrons, electrons). construct and interpret Feynman diagrams showing interactions.know that interactions between fundamental particles (quarks and leptons) are due to the exchange of other particles (vector bosons), and that these are (virtual) photons for the electromagnetic interaction and W +, W - and Z 0 particles for the weak interaction.apply conservation rules to particle interactions, including particle annihilation and creation.know that, for each particle, there exists an antiparticle.use the terms baryon, meson, hadron and lepton.Playing with Particles – a teaching approach for A-level (post-16) particle physics, School Science Review, December 2002, 84 (307), pp 118-123.A resource for particle physics teaching in schools, Physics Education, March 2003, 38, p 107 with sets of online resources.The baryon, meson and lepton cards suggested here have been constructed for this project, but other excellent examples have been published, and it is well worth your considering the following: The first topic makes use of activities based on card sorting and arranging.
