This set of ranking tasks is designed to help the learner work with and understand some of the features of common structures: planar densities, atomic densities, atomic packing factor and coordination numbers of different planes and unit cells.

Tanya Faltens teaches Materials Science and Engineering courses at California State Polytechnic University, Pomona.

Inspired by a workshop on Ranking Tasks by Shane Brown at the ASEE Zone IV Conference in Reno, NV, in 2010.
