Title: Crystal Growth by Evaporation
Url: http://www.maine.gov/doc/nrimc/mgs/education/lessons/act18.htm
Publisher: Maine. Department of Conservation.
Description: This activity introduces students to the idea that crystals 'grow' (crystallize or precipitate) and that minerals or rocks also form this way, providing a very general idea of the nature of magma (molten material that eventually crystallizes into igneous rocks). Using solutions mixed by the teacher, they will observe and sketch the formation of crystals of potassium dichromate and copper II acetate by placing drops of the solutions on microscope slides and drying them on a hot plate. Discussion questions are provided.
