What Variables Affect Crystal Growth?
http://www.micro.magnet.fsu.edu/optics/activities/teachers/variables.html
From DLESE Community Collection (DCC)
Comment on this resource
Students investigate variables that may influence the growth of crystals which they have learned to make. There are two options for implementing this activity. The first is open-ended, with the students deciding what variables affect crystal growth and then deciding on the manipulating variables they would like to study. The second is prescriptive and explains to students how to test three variables in making crystals: temperature, method of mixing (such as shaking or stirring), and concentration.
