Daily Objectives #8  (September 21, 2006)                                                                        Dr. Sanders

By the end of today’s class, you should be able to do the following:


*  REVIEW: Explain what a mineral is, listing the characteristics that all minerals share.  (A side topic: how is a mineral different from a rock?)

*  REVIEW: Explain how to evaluate the mineral properties listed below for a given mineral sample.

           q hardness         q luster         q streak         q specific gravity (similar to density)    
   
      q cleavage         q color       q solubility       q odor

*  Using a mineral identification key, determine the name of a given mineral sample based on its properties.  (For fun, visit the online mineral identification key provided by the Mineralogical Society of America!)

*  Examine and describe the properties of the common minerals that occur in sedimentary rocks.  (Examples to be used in class: First, sample numbers 7, 17, 19, and 20; then 18, 21, 30, and 35.)

*  Examine and describe the properties of the hydrothermal minerals that occur in sedimentary rocks.  (Examples to be used in class: sample numbers 8, 14, 33, 34, 44.)
