Students use Standard Model rules to build hadrons and mesons from quarks.
Students use cleverly constructed puzzle pieces and look for patterns in how those pieces can fit together. The puzzles pieces obey, as much as possible, the Standard Model’s rules limiting the quark composition of bound states, both baryons and mesons. We provide a template that allows the teacher to cut out the puzzle pieces and a "workbench" that students can use for assembly. Image Credit: Eric Gettrust
