Abstract

 

 The present work describes an undergraduate laboratory exercise for improving understanding of fundamental phenomena in cooling crystallization. The exercise of nucleation and crystal growth kinetics supports learning of theories and models presented in lectures and calculation exercises. The teaching methodology incorporates precepts the inclusion of empirical study and data treatment calculations, and promotes collaborative learning through group-working in groups of 4-5 students. The present work includes also the instructions of the exercise and reporting guidance.
