goldberg polyhedron



A goldberg polyhedron is a kind of geodesic dome.  We made a big one out of molecule modelling straws, inspired by Math Monday.  Students from all years were involved in its construction.

It is surprisingly solid when held, but I haven't worked out a way of attaching it to the ceiling yet - or found somewhere big enough to put it!  It's currently taking up half of my classroom!!
