The article describes a student experiment that examines the effect that nanoscale size and shape of molecules have on the macroscopic phase changes of a number of liquid crystals. The author recognizes that phase changes are an important concept in physical science, but are difficult to teach. The authors also provide a number of student activities to determine the melting points of some fatty acids.
