Abstract

In this paper, we present different activities with the aim of understanding and quantifying the growth and formation of minerals under lab conditions. Minerals are crystals that arise naturally. The crystal growth experiments are carried out in both drops of aqueous solutions and silica gel. We compare the halite crystallisation with the precipitation sequence from a brine, we will study the behaviour of the stable and metastable minerals in the Na2SO4 system and, lastly, we will do some research on the gypsum precipitation in silica gels into U-shaped glass tubes. The experiments are easy and inexpensive to perform. They are presented according to the different educational stages (primary school, secondary school and university degrees); it is not obligatory to carry them out, but highly advisable. The experiments have been successfully performed in the different educational stages
