WebActivity 15A is open-ended, students deciding what variables affect crystal growth and then deciding on the manipulating variables they would like to study. Activity 15B is prescriptive and explains to students how to test three variables in making crystals. Following are teacher instructions for both Activity 15A and Activity 15B. WebThe crystal growth rate is 30 μ m h −1. (b) The nucleation rate is determined from the values of n0 and G using Eq. (11.153): The crystal nucleation rate is 2.0×10 9 m −3 h …
