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

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
