On February 11st, Dr. David Jordan lead a discussion about symmetry. We used magnetic 'Magz' pieces as vertices and edges to construct lots of the different shapes, some exhibiting more symmetry than others. Through the activities, we developed different defitions of what it means to be symmetric, and we even formulated a famous conjecture relating the edges, vertices, and faces of a convex polyhedron.
