Lesson: Strangeness Physics

Students will be able to

• recall what the strangeness of each of the quarks and leptons is,
• recall that the strangeness of a composite particle is the sum of the strangeness of each of its constituent particles,
• determine the total strangeness of a set of particles before and after an interaction based on a nuclear equation for that interaction,
• recall that strangeness is conserved in strong and electromagnetic interactions, but not the weak interaction.
